1The output format from "git-diff-index", "git-diff-tree", 2"git-diff-files" and "git diff --raw" are very similar. 3 4These commands all compare two sets of things; what is 5compared differs: 6 7git-diff-index <tree-ish>:: 8 compares the <tree-ish> and the files on the filesystem. 9 10git-diff-index --cached <tree-ish>:: 11 compares the <tree-ish> and the index. 12 13git-diff-tree [-r] <tree-ish-1> <tree-ish-2> [<pattern>...]:: 14 compares the trees named by the two arguments. 15 16git-diff-files [<pattern>...]:: 17 compares the index and the files on the filesystem. 18 19 20An output line is formatted this way: 21 22------------------------------------------------ 23in-place edit :100644 100644 bcd1234... 0123456...

U file6 29------------------------------------------------ 30 31That is, from the left to the right: 32 33. a colon. 34. mode for "src"; 000000 if creation or unmerged. 35. a space. 36. mode for "dst"; 000000 if deletion or unmerged. 37. a space. 38. sha1 for "src"; 0\{40\} if creation or unmerged. 39. a space. 40. sha1 for "dst"; 0\{40\} if creation, unmerged or "look at work tree". 41. a space. 42. status, followed by optional "score" number. 43. a tab or a NUL when '-z' option is used. 44. path for "src" 45. a tab or a NUL when '-z' option is used; only exists for C or R. 46. path for "dst"; only exists for C or R. 47. an LF or a NUL when '-z' option is used, to terminate the record. 48 49<sha1> is shown as all 0's if a file is new on the filesystem 50and it is out of sync with the index. 51 52Example: 53 54------------------------------------------------ 55:100644 100644 5be4a4...... 000000...... M file.c 56------------------------------------------------ 57 58When `-z` option is not used, TAB, LF, and backslash characters 59in pathnames are represented as `\t`, `\n`, and `\\`, 60respectively. 61 62diff format for merges 63---------------------- 64 65"git-diff-tree", "git-diff-files" and "git-diff --raw" 66can take '-c' or '--cc' option 67to generate diff output also for merge commits. The output differs 68from the format described above in the following way: 69 70. there is a colon for each parent 71. there are more "src" modes and "src" sha1 72. status is concatenated status characters for each parent 73. no optional "score" number 74. single path, only for "dst" 75 76Example: 77 78------------------------------------------------ 79::100644 100644 100644 fabadb8... cc95eb0... 4866510... MM describe.c 80------------------------------------------------ 81 82Note that 'combined diff' lists only files which were modified from 83all parents. 84 85 86include::diff-generate-patch.txt[]
