This steals the "pickaxe" feature from JIT and make it available to the bare Plumbing layer. From the command line, the user gives a string he is intersted in. Using the diff-core infrastructure previously introduced, it filters the differences to limit the output only to the diffs between <src> and <dst> where the string appears only in one but not in the other. For example: $ ./git-rev-list HEAD | ./git-diff-tree -Sdiff-tree-helper --stdin -M would show the diffs that touch the string "diff-tree-helper". In real software-archaeologist application, you would typically look for a few to several lines of code and see where that code came from. The "pickaxe" module runs after "rename/copy detection" module, so it even crosses the file rename boundary, as the above example demonstrates.

NAME

|
|
git-diff-files - Compares files in the working tree and the cache
|
|
|
|
|
|
SYNOPSIS
|
|
--------
|
|
'git-diff-files' [-p] [-q] [-r] [-z] [-M] [-C] [-R] [-S<string>] [<pattern>...]
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
Compares the files in the working tree and the cache. When paths
|
|
are specified, compares only those named paths. Otherwise all
|
|
entries in the cache are compared. The output format is the
|
|
same as "git-diff-cache" and "git-diff-tree".
|
|
|
|
OPTIONS
|
|
-------
|
|
-p::
|
|
generate patch (see section on generating patches).
|
|
|
|
-q::
|
|
Remain silent even on nonexisting files
|
|
|
|
-R::
|
|
Output diff in reverse.
|
|
|
|
-M::
|
|
Detect renames; implies -p.
|
|
|
|
-C::
|
|
Detect copies as well as renames; implies -p.
|
|
|
|
-S<string>::
|
|
Look for differences that contains the change in <string>.
|
|
|
|
|
|
-r::
|
|
This flag does not mean anything. It is there only to match
|
|
git-diff-tree. Unlike git-diff-tree, git-diff-files always looks
|
|
at all the subdirectories.
