14 | DESCRIPTION | |
15 | ----------- | |
16 | Compares the content and mode of the blobs found via two tree objects. | |
17 | ||
18 | Note that "git-diff-tree" can use the tree encapsulated in a commit object. | |
19 | ||
20 | OPTIONS | |
21 | ------- | |
22 | <tree-ish>:: | |
23 | The id of a tree object. | |
24 | ||
25 | <pattern>:: | |
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 | |
30 | features. | |
31 | ||
32 | -p:: | |
33 | generate patch (see section on generating patches). For | |
34 | git-diff-tree, this flag implies '-r' as well. | |
35 | ||
5c97558c | 36 | -M:: |
81e50eab | 37 | Detect renames. |
5c97558c | 38 | |
427dcb4b | 39 | -C:: |
81e50eab | 40 | Detect copies as well as renames. |
427dcb4b | 41 | |
e5936382 JH |
42 | -R:: |
43 | Output diff in reverse. | |
44 | ||
52e95789 JH |
45 | -S<string>:: |
46 | Look for differences that contains the change in <string>. | |
47 | ||
2cf565c5 DG |
48 | -r:: |
49 | recurse | |
50 | ||
4cae1a96 JH |
51 | -t:: |
52 | show tree entry itself as well as subtrees. Implies -r. | |
53 | ||
2cf565c5 DG |
54 | -z:: |
55 | \0 line termination on output | |
56 | ||
57 | --stdin:: | |
58 | When '--stdin' is specified, the command does not take | |
59 | <tree-ish> arguments from the command line. Instead, it | |
60 | reads either one <commit> or a pair of <tree-ish> | |
61 | separated with a single space from its standard input. | |
62 | + | |
63 | When a single commit is given on one line of such input, it compares | |
64 | the commit with its parents. The following flags further affects its | |
65 | behaviour. This does not apply to the case where two <tree-ish> | |
66 | separated with a single space are given. | |
67 | ||
68 | -m:: | |
69 | By default, "git-diff-tree --stdin" does not show | |
70 | differences for merge commits. With this flag, it shows | |
71 | differences to that commit from all of its parents. | |
72 | ||
73 | -s:: | |
74 | By default, "git-diff-tree --stdin" shows differences, | |
75 | either in machine-readable form (without '-p') or in patch | |
76 | form (with '-p'). This output can be supressed. It is | |
77 | only useful with '-v' flag. | |
78 | ||
79 | -v:: | |
80 | This flag causes "git-diff-tree --stdin" to also show | |
81 | the commit message before the differences. | |
82 | ||
83 | ||
84 | Limiting Output | |
85 | --------------- | |
86 | If you're only interested in differences in a subset of files, for | |
87 | example some architecture-specific files, you might do: | |
88 | ||
89 | git-diff-tree -r <tree-ish> <tree-ish> arch/ia64 include/asm-ia64 | |
90 | ||
91 | and it will only show you what changed in those two directories. | |
92 | ||
93 | Or if you are searching for what changed in just `kernel/sched.c`, just do | |
94 | ||
95 | git-diff-tree -r <tree-ish> <tree-ish> kernel/sched.c | |
96 | ||
97 | and it will ignore all differences to other files. | |
98 | ||
99 | The pattern is always the prefix, and is matched exactly. There are no | |
100 | wildcards. Even stricter, it has to match complete path comonent. | |
101 | I.e. "foo" does not pick up `foobar.h`. "foo" does match `foo/bar.h` | |
102 | so it can be used to name subdirectories. | |
103 | ||
104 | An example of normal usage is: | |
105 | ||
106 | torvalds@ppc970:~/git> git-diff-tree 5319e4...... | |
107 | *100664->100664 blob ac348b.......->a01513....... git-fsck-cache.c | |
108 | ||
109 | which tells you that the last commit changed just one file (it's from | |
110 | this one: | |
111 | ||
112 | commit 3c6f7ca19ad4043e9e72fa94106f352897e651a8 | |
113 | tree 5319e4d609cdd282069cc4dce33c1db559539b03 | |

117 | ||
118 | Make "git-fsck-cache" print out all the root commits it finds. | |
119 | ||
120 | Once I do the reference tracking, I'll also make it print out all the | |
121 | HEAD commits it finds, which is even more interesting. | |
122 | ||
123 | in case you care). | |
