7 git-diff-tree - Compares the content and mode of blobs found via two tree objects
12 'git-diff-tree' [-p] [-r] [-z] [--stdin] [-B] [-M] [-R] [-C] [-O<orderfile>] [-S<string>] [--pickaxe-all] [-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.
37 Break complete rewrite changes into pairs of delete and create.
43 Detect copies as well as renames.
49 Look for differences that contains the change in <string>.
52 When -S finds a change, show all the changes in that
53 changeset, not just the files that contains the change
57 Output the patch in the order specified in the
58 <orderfile>, which has one shell glob pattern per line.
64 show tree entry itself as well as subtrees. Implies -r.
67 \0 line termination on output
70 When '--root' is specified the initial commit will be showed as a big
71 creation event. This is equivalent to a diff against the NULL tree.
74 When '--stdin' is specified, the command does not take
75 <tree-ish> arguments from the command line. Instead, it
76 reads either one <commit> or a pair of <tree-ish>
77 separated with a single space from its standard input.
79 When a single commit is given on one line of such input, it compares
80 the commit with its parents. The following flags further affects its
81 behaviour. This does not apply to the case where two <tree-ish>
82 separated with a single space are given.
85 By default, "git-diff-tree --stdin" does not show
86 differences for merge commits. With this flag, it shows
87 differences to that commit from all of its parents.
90 By default, "git-diff-tree --stdin" shows differences,
91 either in machine-readable form (without '-p') or in patch
92 form (with '-p'). This output can be supressed. It is
93 only useful with '-v' flag.
96 This flag causes "git-diff-tree --stdin" to also show
97 the commit message before the differences.
102 If you're only interested in differences in a subset of files, for
103 example some architecture-specific files, you might do:
105 git-diff-tree -r <tree-ish> <tree-ish> arch/ia64 include/asm-ia64
107 and it will only show you what changed in those two directories.
109 Or if you are searching for what changed in just `kernel/sched.c`, just do
111 git-diff-tree -r <tree-ish> <tree-ish> kernel/sched.c
113 and it will ignore all differences to other files.
115 The pattern is always the prefix, and is matched exactly. There are no
116 wildcards. Even stricter, it has to match complete path comonent.
117 I.e. "foo" does not pick up `foobar.h`. "foo" does match `foo/bar.h`
118 so it can be used to name subdirectories.
120 An example of normal usage is:
122 torvalds@ppc970:~/git> git-diff-tree 5319e4......
123 *100664->100664 blob ac348b.......->a01513....... git-fsck-cache.c
125 which tells you that the last commit changed just one file (it's from
128 commit 3c6f7ca19ad4043e9e72fa94106f352897e651a8
129 tree 5319e4d609cdd282069cc4dce33c1db559539b03

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