git-archive(1)
==============
NAME
----
git-archive - Creates a archive of the files in the named tree
SYNOPSIS
--------
'git-archive' --format=<fmt> [--list] [--prefix=<prefix>/] [<extra>]
[--remote=<repo>] <tree-ish> [path...]
DESCRIPTION
-----------
Creates an archive of the specified format containing the tree
structure for the named tree. If <prefix> is specified it is
prepended to the filenames in the archive.
'git-archive' behaves differently when given a tree ID versus when
given a commit ID or tag ID. In the first case the current time is
used as modification time of each file in the archive. In the latter
case the commit time as recorded in the referenced commit object is
used instead. Additionally the commit ID is stored in a global
extended pax header if the tar format is used; it can be extracted
using 'git-get-tar-commit-id'. In ZIP files it is stored as a file
comment.
OPTIONS
-------
--format=<fmt>::
Format of the resulting archive: 'tar', 'zip'...
--list::
Show all available formats.
--prefix=<prefix>/::
Prepend <prefix>/ to each filename in the archive.
<extra>::
This can be any options that the archiver backend understand.
--remote=<repo>::
Instead of making a tar archive from local repository,
retrieve a tar archive from a remote repository.
<tree-ish>::
The tree or commit to produce an archive for.
path::
If one or more paths are specified, include only these in the
archive, otherwise include all files and subdirectories.
CONFIGURATION
-------------
By default, file and directories modes are set to 0666 or 0777 in tar
archives. It is possible to change this by setting the "umask" variable
in the repository configuration as follows :
[tar]
umask = 002 ;# group friendly
The special umask value "user" indicates that the user's current umask
will be used instead. The default value remains 0, which means world
readable/writable files and directories.
EXAMPLES
--------
git archive --format=tar --prefix=junk/ HEAD | (cd /var/tmp/ && tar xf -)::
Create a tar archive that contains the contents of the
latest commit on the current branch, and extracts it in
`/var/tmp/junk` directory.
git archive --format=tar --prefix=git-1.4.0/ v1.4.0 | gzip >git-1.4.0.tar.gz::
Create a compressed tarball for v1.4.0 release.
git archive --format=tar --prefix=git-1.4.0/ v1.4.0{caret}\{tree\} | gzip >git-1.4.0.tar.gz::
Create a compressed tarball for v1.4.0 release, but without a
global extended pax header.
git archive --format=zip --prefix=git-docs/ HEAD:Documentation/ > git-1.4.0-docs.zip::
Put everything in the current head's Documentation/ directory
into 'git-1.4.0-docs.zip', with the prefix 'git-docs/'.

Write the pack contents (what would have been written to

--revs::
Read the revision arguments from the standard input, instead of
individual object names. The revision arguments are processed
the same way as gitlink:git-rev-list[1] with `--objects` flag
uses its `commit` arguments to build the list of objects it
outputs. The objects on the resulting list are packed.
--unpacked::
This implies `--revs`. When processing the list of
revision arguments read from the standard input, limit
the objects packed to those that are not already packed.
--all::
This implies `--revs`. In addition to the list of
revision arguments read from the standard input, pretend
as if all refs under `$GIT_DIR/refs` are specifed to be
included.

--window=[N], --depth=[N]::
These two options affects how the objects contained in the pack are
stored using delta compression. The objects are first internally
sorted by type, size and optionally names and compared against the
other objects within `--window` to see if using delta compression saves
space. `--depth` limits the maximum delta depth; making it too deep
affects the performance on the unpacker side, because delta data needs
to be applied that many times to get to the necessary object.

git-upload-archive(1)
====================
NAME
----
git-upload-archive - Send archive
SYNOPSIS
--------
'git-upload-archive' <directory>
DESCRIPTION
-----------
Invoked by 'git-archive --remote' and sends a generated archive to the
other end over the git protocol.
This command is usually not invoked directly by the end user. The UI
for the protocol is on the 'git-archive' side, and the program pair
is meant to be used to get an archive from a remote repository.
OPTIONS
-------
<directory>::
The repository to get a tar archive from.
