Implies -r. 41 42--root:: 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. 45 46--stdin:: 47 When `--stdin` is specified, the command does not take 48 <tree-ish> arguments from the command line. Instead, it 49 reads lines containing either two <tree>, one <commit>, or a 50 list of <commit> from its standard input. (Use a single space 51 as separator.) 52+ 53When two trees are given, it compares the first tree with the second. 54When a single commit is given, it compares the commit with its 55parents. The remaining commits, when given, are used as if they are 56parents of the first commit. 57+ 58When comparing two trees, the ID of both trees (separated by a space 59and terminated by a newline) is printed before the difference. When 60comparing commits, the ID of the first (or only) commit, followed by a 61newline, is printed. 62+ 63The following flags further affect the behavior when comparing 64commits (but not trees). 65 66-m:: 67 By default, 'git diff-tree --stdin' does not show 68 differences for merge commits. With this flag, it shows 69 differences to that commit from all of its parents. See 70 also `-c`. 71 72-s:: 73 By default, 'git diff-tree --stdin' shows differences, 74 either in machine-readable form (without `-p`) or in patch 75 form (with `-p`). This output can be suppressed. It is 76 only useful with `-v` flag. 77 78-v:: 79 This flag causes 'git diff-tree --stdin' to also show 80 the commit message before the differences. 81 82include::pretty-options.txt[] 83 84--no-commit-id:: 85 'git diff-tree' outputs a line with the commit ID when 86 applicable. This flag suppressed the commit ID output. 87 88-c:: 89 This flag changes the way a merge commit is displayed 90 (which means it is useful only when the command is given 91 one <tree-ish>, or `--stdin`). It shows the differences 92 from each of the parents to the merge result simultaneously 93 instead of showing pairwise diff between a parent and the 94 result one at a time (which is what the `-m` option does). 95 Furthermore, it lists only files which were modified 96 from all parents. 97 98--cc:: 99 This flag changes the way a merge commit patch is displayed, 100 in a similar way to the `-c` option. It implies the `-c` 101 and `-p` options and further compresses the patch output 102 by omitting uninteresting hunks whose the contents in the parents 103 have only two variants and the merge result picks one of them 104 without modification. When all hunks are uninteresting, the commit 105 itself and the commit log message is not shown, just like in any other 106 "empty diff" case. 107 108--combined-all-paths:: 109 This flag causes combined diffs (used for merge commits) to 110 list the name of the file from all parents. It thus only has 111 effect when -c or --cc are specified, and is likely only 112 useful if filename changes are detected (i.e. when either 113 rename or copy detection have been requested). 114 115--always:: 116 Show the commit itself and the commit log message even 117 if the diff itself is empty. 118 119 120include::pretty-formats.txt[] 121include::diff-format.txt[] 122 123GIT 124--- 125Part of the linkgit:git[1] suite
