1git-diff-tree(1) 2================ 3v0.1, May 2005 4 5NAME 6---- 7git-diff-tree - Compares the content and mode of blobs found via two tree objects 8 9 10SYNOPSIS 11-------- 12'git-diff-tree' [-p] [-r] [-z] [--stdin] [-M] [-R] [-C] [-S<string>] [-m] [-s] [-v] [-t] <tree-ish> <tree-ish> [<pattern>]\* 13 14DESCRIPTION 15----------- 16Compares the content and mode of the blobs found via two tree objects. 17 18Note that "git-diff-tree" can use the tree encapsulated in a commit object. 19 20OPTIONS 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 36-M:: 37 Detect renames. 38 39-C:: 40 Detect copies as well as renames. 41 42-R:: 43 Output diff in reverse. 44 45-S<string>:: 46 Look for differences that contains the change in <string>. 47 48-r:: 49 recurse 50 51-t:: 52 show tree entry itself as well as subtrees. Implies -r. 53 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+ 63When a single commit is given on one line of such input, it compares 64the commit with its parents. The following flags further affects its 65behaviour. This does not apply to the case where two <tree-ish> 66separated 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 84Limiting Output 85--------------- 86If you're only interested in differences in a subset of files, for 87example some architecture-specific files, you might do: 88 89 git-diff-tree -r <tree-ish> <tree-ish> arch/ia64 include/asm-ia64 90 91and it will only show you what changed in those two directories. 92 93Or 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 97and it will ignore all differences to other files. 98 99The pattern is always the prefix, and is matched exactly. There are no 100wildcards. Even stricter, it has to match complete path comonent. 101I.e. "foo" does not pick up `foobar.h`. "foo" does match `foo/bar.h` 102so it can be used to name subdirectories. 103 104An 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 109which tells you that the last commit changed just one file (it's from 110this one: 111 112 commit 3c6f7ca19ad4043e9e72fa94106f352897e651a8 113 tree 5319e4d609cdd282069cc4dce33c1db559539b03 114 parent b4e628ea30d5ab3606119d2ea5caeab141d38df7 115 author Linus Torvalds <torvalds@ppc970.osdl.org> Sat Apr 9 12:02:30 2005 116 committer Linus Torvalds <torvalds@ppc970.osdl.org> Sat Apr 9 12:02:30 2005 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 123in case you care). 124 125Output format 126------------- 127include::diff-format.txt[] 128 129 130Author 131------ 132Written by Linus Torvalds <torvalds@osdl.org> 133 134Documentation 135-------------- 136Documentation by David Greaves, Junio C Hamano and the git-list <git@vger.kernel.org>. 137 138GIT 139--- 140Part of the link:git.html[git] suite 141
