git for CVS users
=================
So you're a CVS user. That's OK, it's a treatable condition. The job of
this document is to put you on the road to recovery, by helping you
convert an existing cvs repository to git, and by showing you how to use a
git repository in a cvs-like fashion.
Git differs from CVS in that every working tree contains a repository with
a full copy of the project history, and no repository is inherently more
important than any other. However, you can emulate the CVS model by
designating a single shared repository which people can synchronize with;
this document explains how to do that.
Some basic familiarity with git is required. This
link:tutorial.html[tutorial introduction to git] should be sufficient.
First, note some ways that git differs from CVS:
Developing against a shared repository
--------------------------------------
* Commits are atomic and project-wide, not per-file as in CVS.
Suppose a shared repository is set up in /pub/repo.git on the host
foo.com. Then as an individual committer you can clone the shared
repository over ssh with:
* Offline work is supported: you can make multiple commits locally,
then submit them when you're ready.
------------------------------------------------
$ git clone foo.com:/pub/repo.git/ my-project
$ cd my-project
------------------------------------------------
* Branching is fast and easy.
and hack away. The equivalent of `cvs update` is
* Every working tree contains a repository with a full copy of the
project history, and no repository is inherently more important than
any other. However, you can emulate the CVS model by designating a
single shared repository which people can synchronize with; see below
for details.
------------------------------------------------
$ git pull origin
------------------------------------------------
which merges in any work that others might have done since the clone
operation. If there are uncommitted changes in your working tree, commit
them first before running git pull.
[NOTE]
================================
The first `git clone` places the following in the
`my-project/.git/remotes/origin` file, and that's why the previous step
and the next step both work.
------------
URL: foo.com:/pub/project.git/
Pull: refs/heads/master:refs/remotes/origin/master
------------
================================
You can update the shared repository with your changes by first committing
your changes, and then using the gitlink:git-push[1] command:
------------------------------------------------
$ git push origin master
------------------------------------------------
to "push" those commits to the shared repository. If someone else has
updated the repository more recently, `git push`, like `cvs commit`, will
complain, in which case you must pull any changes before attempting the
push again.
In the `git push` command above we specify the name of the remote branch
to update (`master`). If we leave that out, `git push` tries to update
any branches in the remote repository that have the same name as a branch
in the local repository. So the last `push` can be done with either of:
------------
$ git push origin
$ git push foo.com:/pub/project.git/
------------
as long as the shared repository does not have any branches
other than `master`.
Setting Up a Shared Repository
------------------------------
We assume you have already created a git repository for your project,
possibly created from scratch or from a tarball (see the
link:tutorial.html[tutorial]), or imported from an already existing CVS
repository (see the next section).
Assume your existing repo is at /home/alice/myproject. Create a new "bare"
repository (a repository without a working tree) and fetch your project into
it:
------------------------------------------------
$ mkdir /pub/my-repo.git
$ cd /pub/my-repo.git
$ git --bare init-db --shared
$ git --bare fetch /home/alice/myproject master:master
------------------------------------------------
Next, give every team member read/write access to this repository. One
easy way to do this is to give all the team members ssh access to the
machine where the repository is hosted. If you don't want to give them a
full shell on the machine, there is a restricted shell which only allows
users to do git pushes and pulls; see gitlink:git-shell[1].
Put all the committers in the same group, and make the repository
writable by that group:
------------------------------------------------
$ chgrp -R $group /pub/my-repo.git
------------------------------------------------
Make sure committers have a umask of at most 027, so that the directories
they create are writable and searchable by other group members.
Importing a CVS archive
-----------------------
First, install version 2.1 or higher of cvsps from
link:http://www.cobite.com/cvsps/[http://www.cobite.com/cvsps/] and make
sure it is in your path. The magic command line is then
sure it is in your path. Then cd to a checked out CVS working directory
of the project you are interested in and run gitlink:git-cvsimport[1]:
-------------------------------------------
$ git cvsimport -v -d <cvsroot> -C <destination> <module>
$ git cvsimport -C <destination>
-------------------------------------------
This puts a git archive of the named CVS module in the directory
<destination>, which will be created if necessary. The -v option makes
the conversion script very chatty.

The import checks out from CVS every revision of every file. Reportedly

Development Models
------------------
Advanced Shared Repository Management
-------------------------------------
Git allows you to specify scripts called "hooks" to be run at certain
points. You can use these, for example, to send all commits to the shared
repository to a mailing list. See link:hooks.html[Hooks used by git].
You can enforce finer grained permissions using update hooks. See
link:howto/update-hook-example.txt[Controlling access to branches using
update hooks].
Providing CVS Access to a git Repository
----------------------------------------
It is also possible to provide true CVS access to a git repository, so
that developers can still use CVS; see gitlink:git-cvsserver[1] for
details.
Alternative Development Models
------------------------------
CVS users are accustomed to giving a group of developers commit access to
a common repository. In the next section we'll explain how to do this
with git. However, the distributed nature of git allows other development
models, and you may want to first consider whether one of them might be a
better fit for your project.

With a small group, developers may just pull changes from each other's
repositories without the need for a central maintainer.
Emulating the CVS Development Model
-----------------------------------
Start with an ordinary git working directory containing the project, and
remove the checked-out files, keeping just the bare .git directory:
------------------------------------------------
$ mv project/.git /pub/repo.git
$ rm -r project/
------------------------------------------------
Next, give every team member read/write access to this repository. One
easy way to do this is to give all the team members ssh access to the
machine where the repository is hosted. If you don't want to give them a
full shell on the machine, there is a restricted shell which only allows
users to do git pushes and pulls; see gitlink:git-shell[1].
Put all the committers in the same group, and make the repository
writable by that group:

$ chgrp -R $group repo.git
$ find repo.git -mindepth 1 -type d |xargs chmod ug+rwx,g+s
$ GIT_DIR=repo.git git repo-config core.sharedrepository true
------------------------------------------------
Make sure committers have a umask of at most 027, so that the directories
they create are writable and searchable by other group members.
Suppose this repository is now set up in /pub/repo.git on the host
foo.com. Then as an individual committer you can clone the shared
repository:
------------------------------------------------
$ git clone foo.com:/pub/repo.git/ my-project

------------
$ git push origin
$ git push repo.shared.xz:/pub/scm/project.git/
------------
as long as the shared repository does not have any branches
other than `master`.
[NOTE]
============
Because of this behavior, if the shared repository and the developer's
repository both have branches named `origin`, then a push like the above
attempts to update the `origin` branch in the shared repository from the
developer's `origin` branch. The results may be unexpected, so it's
usually best to remove any branch named `origin` from the shared
repository.

link:howto/update-hook-example.txt[Controlling access to branches using

CVS annotate
------------
So, something has gone wrong, and you don't know whom to blame, and
you're an ex-CVS user and used to do "cvs annotate" to see who caused
the breakage. You're looking for the "git annotate", and it's just
claiming not to find such a script. You're annoyed.
Yes, that's right. Core git doesn't do "annotate", although it's
technically possible, and there are at least two specialized scripts out
there that can be used to get equivalent information (see the git
mailing list archives for details).
git has a couple of alternatives, though, that you may find sufficient
or even superior depending on your use. One is called "git-whatchanged"
(for obvious reasons) and the other one is called "pickaxe" ("a tool for
the software archaeologist").
The "git-whatchanged" script is a truly trivial script that can give you
a good overview of what has changed in a file or a directory (or an
arbitrary list of files or directories). The "pickaxe" support is an
additional layer that can be used to further specify exactly what you're
looking for, if you already know the specific area that changed.
Let's step back a bit and think about the reason why you would
want to do "cvs annotate a-file.c" to begin with.
You would use "cvs annotate" on a file when you have trouble
with a function (or even a single "if" statement in a function)
that happens to be defined in the file, which does not do what
you want it to do. And you would want to find out why it was
written that way, because you are about to modify it to suit
your needs, and at the same time you do not want to break its
current callers. For that, you are trying to find out why the
original author did things that way in the original context.
Many times, it may be enough to see the commit log messages of
commits that touch the file in question, possibly along with the
patches themselves, like this:
$ git-whatchanged -p a-file.c
This will show log messages and patches for each commit that
touches a-file.
This, however, may not be very useful when this file has many
modifications that are not related to the piece of code you are
interested in. You would see many log messages and patches that
do not have anything to do with the piece of code you are
interested in. As an example, assuming that you have this piece
of code that you are interested in in the HEAD version:
if (frotz) {
nitfol();
}
you would use git-rev-list and git-diff-tree like this:
$ git-rev-list HEAD |
git-diff-tree --stdin -v -p -S'if (frotz) {
nitfol();
}'
We have already talked about the "\--stdin" form of git-diff-tree
command that reads the list of commits and compares each commit
with its parents (otherwise you should go back and read the tutorial).
The git-whatchanged command internally runs
the equivalent of the above command, and can be used like this:
$ git-whatchanged -p -S'if (frotz) {
nitfol();
}'
When the -S option is used, git-diff-tree command outputs
differences between two commits only if one tree has the
specified string in a file and the corresponding file in the
other tree does not. The above example looks for a commit that
has the "if" statement in it in a file, but its parent commit
does not have it in the same shape in the corresponding file (or
the other way around, where the parent has it and the commit
does not), and the differences between them are shown, along
with the commit message (thanks to the -v flag). It does not
show anything for commits that do not touch this "if" statement.
Also, in the original context, the same statement might have
appeared at first in a different file and later the file was
renamed to "a-file.c". CVS annotate would not help you to go
back across such a rename, but git would still help you in such
a situation. For that, you can give the -C flag to
git-diff-tree, like this:
$ git-whatchanged -p -C -S'if (frotz) {
nitfol();
}'
When the -C flag is used, file renames and copies are followed.
So if the "if" statement in question happens to be in "a-file.c"
in the current HEAD commit, even if the file was originally
called "o-file.c" and then renamed in an earlier commit, or if
the file was created by copying an existing "o-file.c" in an
earlier commit, you will not lose track. If the "if" statement
did not change across such a rename or copy, then the commit that
does rename or copy would not show in the output, and if the
"if" statement was modified while the file was still called
"o-file.c", it would find the commit that changed the statement
when it was in "o-file.c".
NOTE: The current version of "git-diff-tree -C" is not eager
enough to find copies, and it will miss the fact that a-file.c
was created by copying o-file.c unless o-file.c was somehow
changed in the same commit.
You can use the --pickaxe-all flag in addition to the -S flag.
This causes the differences from all the files contained in
those two commits, not just the differences between the files
that contain this changed "if" statement:
$ git-whatchanged -p -C -S'if (frotz) {
nitfol();
}' --pickaxe-all
NOTE: This option is called "--pickaxe-all" because -S
option is internally called "pickaxe", a tool for software
archaeologists.

of such patches via the GIT_EXTERNAL_DIFF and the GIT_DIFF_OPTS
environment variables.
The patch generation can be customized at two levels.
1. When the environment variable 'GIT_EXTERNAL_DIFF' is not set,
these commands internally invoke "diff" like this:
diff -L a/<path> -L b/<path> -pu <old> <new>

For added files, `/dev/null` is used for <old>. For removed
files, `/dev/null` is used for <new>
+
The "diff" formatting options can be customized via the
environment variable 'GIT_DIFF_OPTS'. For example, if you
prefer context diff:
GIT_DIFF_OPTS=-c git-diff-index -p HEAD
2. When the environment variable 'GIT_EXTERNAL_DIFF' is set, the
program named by it is called, instead of the diff invocation
described above.
+
For a path that is added, removed, or modified,
'GIT_EXTERNAL_DIFF' is called with 7 parameters:
path old-file old-hex old-mode new-file new-hex new-mode

where:
<old|new>-file:: are files GIT_EXTERNAL_DIFF can use to read the
contents of <old|new>,
<old|new>-hex:: are the 40-hexdigit SHA1 hashes,
<old|new>-mode:: are the octal representation of the file modes.

The file parameters can point at the user's working file
(e.g. `new-file` in "git-diff-files"), `/dev/null` (e.g. `old-file`
when a new file is added), or a temporary file (e.g. `old-file` in the
index). 'GIT_EXTERNAL_DIFF' should not worry about unlinking the
temporary file --- it is removed when 'GIT_EXTERNAL_DIFF' exits.

NAME
----
git-add - Add files to the index file
git-add - Add file contents to the changeset to be committed next
SYNOPSIS
--------
'git-add' [-n] [-v] [--] <file>...
'git-add' [-n] [-v] [-f] [--interactive] [--] <file>...
DESCRIPTION
-----------
A simple wrapper for git-update-index to add files to the index,
for people used to do "cvs add".
All the changed file contents to be committed together in a single set
of changes must be "added" with the 'add' command before using the
'commit' command. This is not only for adding new files. Even modified
files must be added to the set of changes about to be committed.
This command can be performed multiple times before a commit. The added
content corresponds to the state of specified file(s) at the time the
'add' command is used. This means the 'commit' command will not consider
subsequent changes to already added content if it is not added again before
the commit.
The 'git status' command can be used to obtain a summary of what is included
for the next commit.
This command can be used to add ignored files with `-f` (force)
option, but they have to be
explicitly and exactly specified from the command line. File globbing
and recursive behaviour do not add ignored files.
Please see gitlink:git-commit[1] for alternative ways to add content to a
commit.
It only adds non-ignored files, to add ignored files use
"git update-index --add".
OPTIONS
-------
<file>...::
Files to add to the index (see gitlink:git-ls-files[1]).
Files to add content from. Fileglobs (e.g. `*.c`) can
be given to add all matching files. Also a
leading directory name (e.g. `dir` to add `dir/file1`
and `dir/file2`) can be given to add all files in the
directory, recursively.
-n::
Don't actually add the file(s), just show if they exist.
@ -28,33 +49,25 @@ OPTIONS
-v::
Be verbose.
-f::
Allow adding otherwise ignored files.
\--interactive::
Add modified contents in the working tree interactively to
the index.
\--::
This option can be used to separate command-line options from
the list of files, (useful when filenames might be mistaken
for command-line options).
DISCUSSION
----------
The list of <file> given to the command is fed to `git-ls-files`
command to list files that are not registered in the index and
are not ignored/excluded by `$GIT_DIR/info/exclude` file or
`.gitignore` file in each directory. This means two things:
. You can put the name of a directory on the command line, and
the command will add all files in it and its subdirectories;
. Giving the name of a file that is already in index does not
run `git-update-index` on that path.
EXAMPLES
--------
git-add Documentation/\\*.txt::
Adds all `\*.txt` files that are not in the index under
`Documentation` directory and its subdirectories.
Adds content from all `\*.txt` files under `Documentation`
directory and its subdirectories.

consider `subdir/git-foo.sh`.
Interactive mode
----------------
When the command enters the interactive mode, it shows the
output of the 'status' subcommand, and then goes into ints
interactive command loop.
The command loop shows the list of subcommands available, and
gives a prompt "What now> ". In general, when the prompt ends
with a single '>', you can pick only one of the choices given
and type return, like this:
------------
*** Commands ***
1: status 2: update 3: revert 4: add untracked
5: patch 6: diff 7: quit 8: help
What now> 1
------------
You also could say "s" or "sta" or "status" above as long as the
choice is unique.
The main command loop has 6 subcommands (plus help and quit).
status::
This shows the change between HEAD and index (i.e. what will be
committed if you say "git commit"), and between index and
working tree files (i.e. what you could stage further before
"git commit" using "git-add") for each path. A sample output
looks like this:
+
------------
staged unstaged path
1: binary nothing foo.png
2: +403/-35 +1/-1 git-add--interactive.perl
------------
+
It shows that foo.png has differences from HEAD (but that is
binary so line count cannot be shown) and there is no
difference between indexed copy and the working tree
version (if the working tree version were also different,
'binary' would have been shown in place of 'nothing'). The
other file, git-add--interactive.perl, has 403 lines added
and 35 lines deleted if you commit what is in the index, but
working tree file has further modifications (one addition and
one deletion).
update::
This shows the status information and gives prompt
"Update>>". When the prompt ends with double '>>', you can
make more than one selection, concatenated with whitespace or
comma. Also you can say ranges. E.g. "2-5 7,9" to choose
2,3,4,5,7,9 from the list. You can say '*' to choose
everything.
+
What you chose are then highlighted with '*',
like this:
+
------------
staged unstaged path
1: binary nothing foo.png
* 2: +403/-35 +1/-1 git-add--interactive.perl
------------
+
To remove selection, prefix the input with `-`
like this:
+
------------
Update>> -2
------------
+
After making the selection, answer with an empty line to stage the
contents of working tree files for selected paths in the index.
revert::
This has a very similar UI to 'update', and the staged
information for selected paths are reverted to that of the
HEAD version. Reverting new paths makes them untracked.
add untracked::
This has a very similar UI to 'update' and
'revert', and lets you add untracked paths to the index.
patch::
This lets you choose one path out of 'status' like selection.
After choosing the path, it presents diff between the index
and the working tree file and asks you if you want to stage
the change of each hunk. You can say:
y - add the change from that hunk to index
n - do not add the change from that hunk to index
a - add the change from that hunk and all the rest to index
d - do not the change from that hunk nor any of the rest to index
j - do not decide on this hunk now, and view the next
undecided hunk
J - do not decide on this hunk now, and view the next hunk
k - do not decide on this hunk now, and view the previous
undecided hunk
K - do not decide on this hunk now, and view the previous hunk
+
After deciding the fate for all hunks, if there is any hunk
that was chosen, the index is updated with the selected hunks.
diff::
This lets you review what will be committed (i.e. between
HEAD and index).

DESCRIPTION
-----------
Clones a repository into a newly created directory. All remote
branch heads are copied under `$GIT_DIR/refs/heads/`, except
that the remote `master` is also copied to `origin` branch.
In addition, `$GIT_DIR/remotes/origin` file is set up to have
this line:
Clones a repository into a newly created directory, creates
remote-tracking branches for each branch in the cloned repository
(visible using `git branch -r`), and creates and checks out a master
branch equal to the cloned repository's master branch.
Pull: master:origin
This is to help the typical workflow of working off of the
remote `master` branch. Every time `git pull` without argument
is run, the progress on the remote `master` branch is tracked by
copying it into the local `origin` branch, and merged into the
branch you are currently working on. Remote branches other than
`master` are also added there to be tracked.
After the clone, a plain `git fetch` without arguments will update
all the remote-tracking branches, and a `git pull` without
arguments will in addition merge the remote master branch into the
current branch.
This default configuration is achieved by creating references to
the remote branch heads under `$GIT_DIR/refs/remotes/origin` and
by initializing `remote.origin.url` and `remote.origin.fetch`
configuration variables.

DESCRIPTION
-----------
Updates the index file for given paths, or all modified files if
'-a' is specified, and makes a commit object. The command specified
by either the VISUAL or EDITOR environment variables are used to edit
the commit log message.
Use 'git commit' when you want to record your changes into the repository
along with a log message describing what the commit is about. All changes
to be committed must be explicitly identified using one of the following
methods:
Several environment variable are used during commits. They are
documented in gitlink:git-commit-tree[1].
1. by using gitlink:git-add[1] to incrementally "add" changes to the
next commit before using the 'commit' command (Note: even modified
files must be "added");
2. by using gitlink:git-rm[1] to identify content removal for the next
commit, again before using the 'commit' command;
3. by directly listing files containing changes to be committed as arguments
to the 'commit' command, in which cases only those files alone will be
considered for the commit;
4. by using the -a switch with the 'commit' command to automatically "add"
changes from all known files i.e. files that have already been committed
before, and perform the actual commit.
The gitlink:git-status[1] command can be used to obtain a
summary of what is included by any of the above for the next
commit by giving the same set of parameters you would give to
this command.
If you make a commit and then found a mistake immediately after
that, you can recover from it with gitlink:git-reset[1].
This command can run `commit-msg`, `pre-commit`, and
`post-commit` hooks. See link:hooks.html[hooks] for more
information.

Files to be committed. The meaning of these is
different between `--include` and `--only`. Without
either, it defaults `--only` semantics.
If you make a commit and then found a mistake immediately after
that, you can recover from it with gitlink:git-reset[1].
When files are given on the command line, the command
commits the contents of the named files, without
recording the changes already staged. The contents of
these files are also staged for the next commit on top
of what have been staged before.
Discussion
----------
EXAMPLES
--------
When recording your own work, the contents of modified files in
your working tree are temporarily stored to a staging area
called the "index" with gitlink:git-add[1]. Removal
of a file is staged with gitlink:git-rm[1]. After building the
state to be committed incrementally with these commands, `git
commit` (without any pathname parameter) is used to record what
has been staged so far. This is the most basic form of the
command. An example:
`git commit` without _any_ parameter commits the tree structure
recorded by the current index file. This is a whole-tree commit
even the command is invoked from a subdirectory.
------------
$ edit hello.c
$ git rm goodbye.c
$ git add hello.c
$ git commit
------------
`git commit --include paths...` is equivalent to
////////////
We should fix 'git rm' to remove goodbye.c from both index and
working tree for the above example.
////////////
git update-index --remove paths...
git commit
Instead of staging files after each individual change, you can
tell `git commit` to notice the changes to the files whose
contents are tracked in
your working tree and do corresponding `git add` and `git rm`
for you. That is, this example does the same as the earlier
example if there is no other change in your working tree:
That is, update the specified paths to the index and then commit
the whole tree.
------------
$ edit hello.c
$ rm goodbye.c
$ git commit -a
------------
`git commit paths...` largely bypasses the index file and
commits only the changes made to the specified paths. It has
however several safety valves to prevent confusion.
The command `git commit -a` first looks at your working tree,
notices that you have modified hello.c and removed goodbye.c,
and performs necessary `git add` and `git rm` for you.
. It refuses to run during a merge (i.e. when
`$GIT_DIR/MERGE_HEAD` exists), and reminds trained git users
that the traditional semantics now needs -i flag.
After staging changes to many files, you can alter the order the
changes are recorded in, by giving pathnames to `git commit`.
When pathnames are given, the command makes a commit that
only records the changes made to the named paths:
. It refuses to run if named `paths...` are different in HEAD
and the index (ditto about reminding). Added paths are OK.
This is because an earlier `git diff` (not `git diff HEAD`)
would have shown the differences since the last `git
update-index paths...` to the user, and an inexperienced user
may mistakenly think that the changes between the index and
the HEAD (i.e. earlier changes made before the last `git
update-index paths...` was done) are not being committed.
------------
$ edit hello.c hello.h
$ git add hello.c hello.h
$ edit Makefile
$ git commit Makefile
------------
. It reads HEAD commit into a temporary index file, updates the
specified `paths...` and makes a commit. At the same time,
the real index file is also updated with the same `paths...`.
This makes a commit that records the modification to `Makefile`.
The changes staged for `hello.c` and `hello.h` are not included
in the resulting commit. However, their changes are not lost --
they are still staged and merely held back. After the above
sequence, if you do:
`git commit --all` updates the index file with _all_ changes to
the working tree, and makes a whole-tree commit, regardless of
which subdirectory the command is invoked in.
------------
$ git commit
------------
this second commit would record the changes to `hello.c` and
`hello.h` as expected.
After a merge (initiated by either gitlink:git-merge[1] or
gitlink:git-pull[1]) stops because of conflicts, cleanly merged
paths are already staged to be committed for you, and paths that
conflicted are left in unmerged state. You would have to first
check which paths are conflicting with gitlink:git-status[1]
and after fixing them manually in your working tree, you would
stage the result as usual with gitlink:git-add[1]:
------------
$ git status | grep unmerged
unmerged: hello.c
$ edit hello.c
$ git add hello.c
------------
After resolving conflicts and staging the result, `git ls-files -u`
would stop mentioning the conflicted path. When you are done,
run `git commit` to finally record the merge:
------------
$ git commit
------------
As with the case to record your own changes, you can use `-a`
option to save typing. One difference is that during a merge
resolution, you cannot use `git commit` with pathnames to
alter the order the changes are committed, because the merge
should be recorded as a single commit. In fact, the command
refuses to run when given pathnames (but see `-i` option).
ENVIRONMENT VARIABLES
---------------------
The command specified by either the VISUAL or EDITOR environment
variables is used to edit the commit log message.
HOOKS

SYNOPSIS
--------
'git-diff' [ --diff-options ] <tree-ish>{0,2} [<path>...]
'git-diff' [ --diff-options ] <commit>{0,2} [--] [<path>...]
DESCRIPTION
-----------
Show changes between two trees, a tree and the working tree, a
tree and the index file, or the index file and the working tree.
The combination of what is compared with what is determined by
the number of trees given to the command.
* When no <tree-ish> is given, the working tree and the index
file are compared, using `git-diff-files`.
'git-diff' [--options] [--] [<path>...]::
* When one <tree-ish> is given, the working tree and the named
tree are compared, using `git-diff-index`. The option
`--cached` can be given to compare the index file and
the named tree.
This form is to view the changes you made relative to
the index (staging area for the next commit). In other
words, the differences are what you _could_ tell git to
further add to the index but you still haven't. You can
stage these changes by using gitlink:git-add[1].
'git-diff' [--options] --cached [<commit>] [--] [<path>...]::
This form is to view the changes you staged for the next
commit relative to the named <commit>. Typically you
would want comparison with the latest commit, so if you
do not give <commit>, it defaults to HEAD.
'git-diff' [--options] <commit> [--] [<path>...]::
This form is to view the changes you have in your
working tree relative to the named <commit>. You can
use HEAD to compare it with the latest commit, or a
branch name to compare with the tip of a different
branch.
'git-diff' [--options] <commit> <commit> [--] [<path>...]::
This form is to view the changes between two <commit>,
for example, tips of two branches.
Just in case if you are doing something exotic, it should be
noted that all of the <commit> in the above description can be
any <tree-ish>.
* When two <tree-ish>s are given, these two trees are compared
using `git-diff-tree`.
OPTIONS
-------
--diff-options::
'--diff-options' are passed to the `git-diff-files`,
`git-diff-index`, and `git-diff-tree` commands. See the
documentation for these commands for description.

<path>...::
The <path> arguments are also passed to `git-diff-\*`

NAME
----
git-merge-file - three-way file merge
SYNOPSIS
--------
[verse]
'git-merge-file' [-L <current-name> [-L <base-name> [-L <other-name>]]]
[-p|--stdout] [-q|--quiet] <current-file> <base-file> <other-file>
DESCRIPTION
-----------
git-file-merge incorporates all changes that lead from the `<base-file>`
to `<other-file>` into `<current-file>`. The result ordinarily goes into
`<current-file>`. git-merge-file is useful for combining separate changes
to an original. Suppose `<base-file>` is the original, and both
`<current-file>` and `<other-file>` are modifications of `<base-file>`.
Then git-merge-file combines both changes.
A conflict occurs if both `<current-file>` and `<other-file>` have changes
in a common segment of lines. If a conflict is found, git-merge-file
normally outputs a warning and brackets the conflict with <<<<<<< and
>>>>>>> lines. A typical conflict will look like this:
<<<<<<< A
lines in file A
=======
lines in file B
>>>>>>> B
If there are conflicts, the user should edit the result and delete one of
the alternatives.
The exit value of this program is negative on error, and the number of
conflicts otherwise. If the merge was clean, the exit value is 0.
git-merge-file is designed to be a minimal clone of RCS merge, that is, it
implements all of RCS merge's functionality which is needed by
gitlink:git[1].
OPTIONS
-------
-L <label>::
This option may be given up to three times, and
specifies labels to be used in place of the
corresponding file names in conflict reports. That is,
`git-merge-file -L x -L y -L z a b c` generates output that
looks like it came from files x, y and z instead of
from files a, b and c.
-p::
Send results to standard output instead of overwriting
`<current-file>`.
-q::
Quiet; do not warn about conflicts.
EXAMPLES
--------
git merge-file README.my README README.upstream::
combines the changes of README.my and README.upstream since README,
tries to merge them and writes the result into README.my.
git merge-file -L a -L b -L c tmp/a123 tmp/b234 tmp/c345::
merges tmp/a123 and tmp/c345 with the base tmp/b234, but uses labels
`a` and `c` instead of `tmp/a123` and `tmp/c345`.

When running the command with `-u` and `-m` options, the
merge result may need to overwrite paths that are not
tracked in the current branch. The command usually
refuses to proceed with the merge to avoid losing such a
path. However this safety valve sometimes gets in the
way. For example, it often happens that the other
branch added a file that used to be a generated file in
your branch, and the safety valve triggers when you try
to switch to that branch after you ran `make` but before
running `make clean` to remove the generated file. This
option tells the command to read per-directory exclude

SYNOPSIS

'git-rm' [-f] [-n] [-v] [--] <file>...
'git-rm' [-f] [-n] [-r] [--cached] [--] <file>...
DESCRIPTION
-----------
A convenience wrapper for git-update-index --remove. For those coming
from cvs, git-rm provides an operation similar to "cvs rm" or "cvs
remove".
Remove files from the working tree and from the index. The
files have to be identical to the tip of the branch, and no
updates to its contents must have been placed in the staging
area (aka index).
OPTIONS
-------
<file>...::
Files to remove from the index and optionally, from the
working tree as well.
Files to remove. Fileglobs (e.g. `*.c`) can be given to
remove all matching files. Also a leading directory name
(e.g. `dir` to add `dir/file1` and `dir/file2`) can be
given to remove all files in the directory, recursively,
but this requires `-r` option to be given for safety.
-f::
Remove files from the working tree as well as from the index.
Override the up-to-date check.
-n::
Don't actually remove the file(s), just show if they exist in
the index.
-v::
Be verbose.
-r::
Allow recursive removal when a leading directory name is
given.
\--::
This option can be used to separate command-line options from
the list of files, (useful when filenames might be mistaken
for command-line options).
\--cached::
This option can be used to tell the command to remove
the paths only from the index, leaving working tree
files.
DISCUSSION
----------
The list of <file> given to the command is fed to `git-ls-files`
command to list files that are registered in the index and
are not ignored/excluded by `$GIT_DIR/info/exclude` file or
`.gitignore` file in each directory. This means two things:
. You can put the name of a directory on the command line, and the
command will remove all files in it and its subdirectories (the
directories themselves are never removed from the working tree);
. Giving the name of a file that is not in the index does not
remove that file.
The list of <file> given to the command can be exact pathnames,
file glob patterns, or leading directory name. The command
removes only the paths that is known to git. Giving the name of
a file that you have not told git about does not remove that file.

Merge tracking in Subversion is lacking and doing branched development

branches or directories in a Subversion repository, git-svn has a simple
hack to allow it to track an arbitrary number of related _or_ unrelated
SVN repositories via one git repository. Simply set the GIT_SVN_ID

In the past, `.git/HEAD` was a symbolic link pointing at

we did `ln -sf refs/heads/newbranch .git/HEAD`, and when we wanted
to find out which branch we are on, we did `readlink .git/HEAD`.
This was fine, and internally that is what still happens by

Git tracks content not files

then commit as usual. No special command is required when removing a
file; just remove it, then commit.
With git you have to explicitly "add" all the changed _content_ you
want to commit together. This can be done in a few different ways:
1) By using 'git add <file_spec>...'
This can be performed multiple times before a commit. Note that this
is not only for adding new files. Even modified files must be
added to the set of changes about to be committed. The "git status"
command gives you a summary of what is included so far for the
next commit. When done you should use the 'git commit' command to
make it real.
Note: don't forget to 'add' a file again if you modified it after the
first 'add' and before 'commit'. Otherwise only the previous added
state of that file will be committed. This is because git tracks
content, so what you're really 'add'ing to the commit is the *content*
of the file in the state it is in when you 'add' it.
2) By using 'git commit -a' directly
This is a quick way to automatically 'add' the content from all files
that were modified since the previous commit, and perform the actual
commit without having to separately 'add' them beforehand. This will
not add content from new files i.e. files that were never added before.
Those files still have to be added explicitly before performing a
commit.
But here's a twist. If you do 'git commit <file1> <file2> ...' then only
the changes belonging to those explicitly specified files will be
committed, entirely bypassing the current "added" changes. Those "added"
changes will still remain available for a subsequent commit though.
However, for normal usage you only have to remember 'git add' + 'git commit'
and/or 'git commit -a'.

"master" argument in the above command is actually unnecessary, as it
is the default.)
This merges Bob's changes into her repository; "git log" will
now show the new commits. If Alice has made her own changes in the
meantime, then Bob's changes will be merged in, and she will need to
manually fix any conflicts.
The "pull" command thus performs two operations: it fetches changes
from a remote branch, then merges them into the current branch.
A more cautious Alice might wish to examine Bob's changes before
pulling them. She can do this by creating a temporary branch just
for the purpose of studying Bob's changes:
You can perform the first operation alone using the "git fetch"
command. For example, Alice could create a temporary branch just to
track Bob's changes, without merging them with her own, using:
-------------------------------------
$ git fetch /home/bob/myrepo master:bob-incoming
-------------------------------------
which fetches the changes from Bob's master branch into a new branch
named bob-incoming. (Unlike git pull, git fetch just fetches a copy
of Bob's line of development without doing any merging). Then
named bob-incoming. Then
-------------------------------------
$ git log -p master..bob-incoming

The last command is a pull from the "bob-incoming" branch in Alice's
own repository.
Alice could also perform both steps at once with:
-------------------------------------
$ git pull /home/bob/myrepo master:bob-incoming
-------------------------------------
This is just like the "git pull /home/bob/myrepo master" that we saw
before, except that it also stores the unmerged changes from bob's
master branch in bob-incoming before merging them into Alice's
current branch. Note that git pull always merges into the current
branch, regardless of what else is given on the commandline.

- expat library; git-http-push uses it for remote lock
management over DAV. Similar to "curl" above, this is optional.
- "GNU diff" to generate patches. Of course, you don't _have_ to
generate patches if you don't want to, but let's face it, you'll
be wanting to. Or why did you get git in the first place?
Non-GNU versions of the diff/patch programs don't generally support
the unified patch format (which is the one git uses), so you
really do want to get the GNU one. Trust me, you will want to
do that even if it wasn't for git. There's no point in living
in the dark ages any more.
- "merge", the standard UNIX three-way merge program. It usually
comes with the "rcs" package on most Linux distributions, so if
you have a developer install you probably have it already, but a
"graphical user desktop" install might have left it out.
You'll only need the merge program if you do development using
git, and if you only use git to track other peoples work you'll
never notice the lack of it.
- "wish", the Tcl/Tk windowing shell is used in gitk to show the
history graphically
