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] [-C] [-S<string>] [-m] [-s] [-v] [-t] <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.
40 Detect copies as well as renames.
43 Output diff in reverse.
46 Look for differences that contains the change in <string>.
52 show tree entry itself as well as subtrees. Implies -r.
55 \0 line termination on output
58 When '--root' is specified the initial commit will be showed as a big
59 creation event. This is equivalent to a diff against the NULL tree.
62 When '--stdin' is specified, the command does not take
63 <tree-ish> arguments from the command line. Instead, it
64 reads either one <commit> or a pair of <tree-ish>
65 separated with a single space from its standard input.
67 When a single commit is given on one line of such input, it compares
68 the commit with its parents. The following flags further affects its
69 behaviour. This does not apply to the case where two <tree-ish>
70 separated with a single space are given.
73 By default, "git-diff-tree --stdin" does not show
74 differences for merge commits. With this flag, it shows
75 differences to that commit from all of its parents.
78 By default, "git-diff-tree --stdin" shows differences,
79 either in machine-readable form (without '-p') or in patch
80 form (with '-p'). This output can be supressed. It is
81 only useful with '-v' flag.
84 This flag causes "git-diff-tree --stdin" to also show
85 the commit message before the differences.
90 If you're only interested in differences in a subset of files, for
91 example some architecture-specific files, you might do:
93 git-diff-tree -r <tree-ish> <tree-ish> arch/ia64 include/asm-ia64
95 and it will only show you what changed in those two directories.
97 Or if you are searching for what changed in just `kernel/sched.c`, just do
99 git-diff-tree -r <tree-ish> <tree-ish> kernel/sched.c
101 and it will ignore all differences to other files.
103 The pattern is always the prefix, and is matched exactly. There are no
104 wildcards. Even stricter, it has to match complete path comonent.
105 I.e. "foo" does not pick up `foobar.h`. "foo" does match `foo/bar.h`
106 so it can be used to name subdirectories.
108 An example of normal usage is:
110 torvalds@ppc970:~/git> git-diff-tree 5319e4......
111 *100664->100664 blob ac348b.......->a01513....... git-fsck-cache.c
113 which tells you that the last commit changed just one file (it's from
116 commit 3c6f7ca19ad4043e9e72fa94106f352897e651a8
117 tree 5319e4d609cdd282069cc4dce33c1db559539b03
118 parent b4e628ea30d5ab3606119d2ea5caeab141d38df7

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