6 git-diff-tree - Compares the content and mode of blobs found via two tree objects
12 'git diff-tree' [--stdin] [-m] [-s] [-v] [--no-commit-id] [--pretty]
13 [-t] [-r] [-c | --cc] [--combined-all-paths] [--root] [--merge-base]
14 [<common-diff-options>] <tree-ish> [<tree-ish>] [<path>...]
18 Compares the content and mode of the blobs found via two tree objects.
20 If there is only one <tree-ish> given, the commit is compared with its parents
23 Note that 'git diff-tree' can use the tree encapsulated in a commit object.

30 The id of a tree object.
33 If provided, the results are limited to a subset of files
34 matching one of the provided pathspecs.
37 recurse into sub-trees
40 show tree entry itself as well as subtrees. Implies -r.
43 When `--root` is specified the initial commit will be shown as a big
44 creation event. This is equivalent to a diff against the NULL tree.
47 Instead of comparing the <tree-ish>s directly, use the merge
48 base between the two <tree-ish>s as the "before" side. There
49 must be two <tree-ish>s given and they must both be commits.
52 When `--stdin` is specified, the command does not take
53 <tree-ish> arguments from the command line. Instead, it
54 reads lines containing either two <tree>, one <commit>, or a
55 list of <commit> from its standard input. (Use a single space
58 When two trees are given, it compares the first tree with the second.
59 When a single commit is given, it compares the commit with its
60 parents. The remaining commits, when given, are used as if they are
61 parents of the first commit.
63 When comparing two trees, the ID of both trees (separated by a space
64 and terminated by a newline) is printed before the difference. When
65 comparing commits, the ID of the first (or only) commit, followed by a
68 The following flags further affect the behavior when comparing
69 commits (but not trees).
72 By default, 'git diff-tree --stdin' does not show
73 differences for merge commits. With this flag, it shows
74 differences to that commit from all of its parents. See
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 suppressed. 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.
87 include::pretty-options.txt[]
90 'git diff-tree' outputs a line with the commit ID when
91 applicable. This flag suppressed the commit ID output.
94 This flag changes the way a merge commit is displayed
95 (which means it is useful only when the command is given
96 one <tree-ish>, or `--stdin`). It shows the differences
97 from each of the parents to the merge result simultaneously
98 instead of showing pairwise diff between a parent and the
99 result one at a time (which is what the `-m` option does).
100 Furthermore, it lists only files which were modified
104 This flag changes the way a merge commit patch is displayed,
105 in a similar way to the `-c` option. It implies the `-c`
106 and `-p` options and further compresses the patch output
107 by omitting uninteresting hunks whose the contents in the parents
108 have only two variants and the merge result picks one of them
109 without modification. When all hunks are uninteresting, the commit
110 itself and the commit log message is not shown, just like in any other
113 --combined-all-paths::
114 This flag causes combined diffs (used for merge commits) to
115 list the name of the file from all parents. It thus only has
116 effect when -c or --cc are specified, and is likely only
117 useful if filename changes are detected (i.e. when either
118 rename or copy detection have been requested).
121 Show the commit itself and the commit log message even
122 if the diff itself is empty.
