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] [-R] [-m] [-s] [-v] <tree-ish> <tree-ish> [<pattern>]\*
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 pattern 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 Detect renames; implies -p, in turn implying also '-r'.
40 Output diff in reverse.
46 \0 line termination on output
49 When '--stdin' is specified, the command does not take
50 <tree-ish> arguments from the command line. Instead, it
51 reads either one <commit> or a pair of <tree-ish>
52 separated with a single space from its standard input.
54 When a single commit is given on one line of such input, it compares
55 the commit with its parents. The following flags further affects its
56 behaviour. This does not apply to the case where two <tree-ish>
57 separated with a single space are given.
60 By default, "git-diff-tree --stdin" does not show
61 differences for merge commits. With this flag, it shows
62 differences to that commit from all of its parents.
65 By default, "git-diff-tree --stdin" shows differences,
66 either in machine-readable form (without '-p') or in patch
67 form (with '-p'). This output can be supressed. It is
68 only useful with '-v' flag.
71 This flag causes "git-diff-tree --stdin" to also show
72 the commit message before the differences.
77 If you're only interested in differences in a subset of files, for
78 example some architecture-specific files, you might do:
80 git-diff-tree -r <tree-ish> <tree-ish> arch/ia64 include/asm-ia64
82 and it will only show you what changed in those two directories.
84 Or if you are searching for what changed in just `kernel/sched.c`, just do
86 git-diff-tree -r <tree-ish> <tree-ish> kernel/sched.c
88 and it will ignore all differences to other files.
90 The pattern is always the prefix, and is matched exactly. There are no
91 wildcards. Even stricter, it has to match complete path comonent.
92 I.e. "foo" does not pick up `foobar.h`. "foo" does match `foo/bar.h`
93 so it can be used to name subdirectories.
95 An example of normal usage is:
97 torvalds@ppc970:~/git> git-diff-tree 5319e4......
98 *100664->100664 blob ac348b.......->a01513....... git-fsck-cache.c
100 which tells you that the last commit changed just one file (it's from
103 commit 3c6f7ca19ad4043e9e72fa94106f352897e651a8
104 tree 5319e4d609cdd282069cc4dce33c1db559539b03
105 parent b4e628ea30d5ab3606119d2ea5caeab141d38df7

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