7 git-diff-tree - Compares the content and mode of blobs found via two tree objects
12 'git-diff-tree' [-p] [-r] [-z] [--stdin] [-m] [-s] [-v] [-t] [-R] [-B] [-M] [-C] [--find-copies-harder] [-O<orderfile>] [-S<string>] [--pickaxe-all] <tree-ish> <tree-ish> [<path>...]
16 Compares the content and mode of the blobs found via two tree objects.
18 Note that "git-diff-tree" can use the tree encapsulated in a commit object.
23 The id of a tree object.
26 If provided, the results are limited to a subset of files
27 matching one of these prefix strings.
28 ie file matches `/^<pattern1>|<pattern2>|.../`
29 Note that this parameter does not provide any wildcard or regexp
33 generate patch (see section on generating patches). For
34 git-diff-tree, this flag implies '-r' as well.
37 Break complete rewrite changes into pairs of delete and create.
43 Detect copies as well as renames.
45 --find-copies-harder::
46 By default, -C option finds copies only if the original
47 file of the copy was modified in the same changeset for
48 performance reasons. This flag makes the command
49 inspect unmodified files as candidates for the source of
50 copy. This is a very expensive operation for large
51 projects, so use it with caution.
57 Look for differences that contains the change in <string>.
60 When -S finds a change, show all the changes in that
61 changeset, not just the files that contains the change
65 Output the patch in the order specified in the
66 <orderfile>, which has one shell glob pattern per line.
72 show tree entry itself as well as subtrees. Implies -r.
75 \0 line termination on output
78 When '--root' is specified the initial commit will be showed as a big
79 creation event. This is equivalent to a diff against the NULL tree.
82 When '--stdin' is specified, the command does not take
83 <tree-ish> arguments from the command line. Instead, it
84 reads either one <commit> or a pair of <tree-ish>
85 separated with a single space from its standard input.
87 When a single commit is given on one line of such input, it compares
88 the commit with its parents. The following flags further affects its
89 behaviour. This does not apply to the case where two <tree-ish>
90 separated with a single space are given.
93 By default, "git-diff-tree --stdin" does not show
94 differences for merge commits. With this flag, it shows
95 differences to that commit from all of its parents.
98 By default, "git-diff-tree --stdin" shows differences,
99 either in machine-readable form (without '-p') or in patch
100 form (with '-p'). This output can be supressed. It is
101 only useful with '-v' flag.
104 This flag causes "git-diff-tree --stdin" to also show
105 the commit message before the differences.
107 --pretty[=(raw|medium|short)]::
108 This is used to control "pretty printing" format of the
109 commit message. Without "=<style>", it defaults to
115 If you're only interested in differences in a subset of files, for
116 example some architecture-specific files, you might do:
118 git-diff-tree -r <tree-ish> <tree-ish> arch/ia64 include/asm-ia64
120 and it will only show you what changed in those two directories.
122 Or if you are searching for what changed in just `kernel/sched.c`, just do
124 git-diff-tree -r <tree-ish> <tree-ish> kernel/sched.c
126 and it will ignore all differences to other files.
128 The pattern is always the prefix, and is matched exactly. There are no
129 wildcards. Even stricter, it has to match complete path comonent.
130 I.e. "foo" does not pick up `foobar.h`. "foo" does match `foo/bar.h`
131 so it can be used to name subdirectories.
133 An example of normal usage is:
135 torvalds@ppc970:~/git> git-diff-tree 5319e4......
136 *100664->100664 blob ac348b.......->a01513....... git-fsck-cache.c
138 which tells you that the last commit changed just one file (it's from

147 Make "git-fsck-cache" print out all the root commits it finds.
149 Once I do the reference tracking, I'll also make it print out all the
150 HEAD commits it finds, which is even more interesting.
