2 Generate patch (see section on generating patches)
8 Generate the raw format.
11 Synonym for "-p --raw".
13 --stat[=width[,name-width]]::
14 Generate a diffstat. You can override the default
15 output width for 80-column terminal by "--stat=width".
16 The width of the filename part can be controlled by
17 giving another width to it separated by a comma.
20 Similar to \--stat, but shows number of added and
21 deleted lines in decimal notation and pathname without
22 abbreviation, to make it more machine friendly. For
23 binary files, outputs two `-` instead of saying
27 Output only the last line of the --stat format containing total
28 number of modified files, as well as number of added and deleted
32 Output a condensed summary of extended header information
33 such as creations, renames and mode changes.
36 Synonym for "-p --stat".
39 \0 line termination on output
42 Show only names of changed files.
45 Show only names and status of changed files.
51 Turn off colored diff, even when the configuration file
52 gives the default to color output.
55 Show colored word diff, i.e. color words which have changed.
58 Turn off rename detection, even when the configuration
59 file gives the default to do so.
62 Warn if changes introduce trailing whitespace
63 or an indent that uses a space before a tab.
66 Instead of the first handful characters, show full
67 object name of pre- and post-image blob on the "index"
68 line when generating a patch format output.
71 In addition to --full-index, output "binary diff" that
72 can be applied with "git apply".
75 Instead of showing the full 40-byte hexadecimal object
76 name in diff-raw format output and diff-tree header
77 lines, show only handful hexdigits prefix. This is
78 independent of --full-index option above, which controls
79 the diff-patch output format. Non default number of
80 digits can be specified with --abbrev=<n>.
83 Break complete rewrite changes into pairs of delete and create.
89 Detect copies as well as renames. See also `--find-copies-harder`.
91 --diff-filter=[ACDMRTUXB*]::
92 Select only files that are Added (`A`), Copied (`C`),
93 Deleted (`D`), Modified (`M`), Renamed (`R`), have their
94 type (mode) changed (`T`), are Unmerged (`U`), are
95 Unknown (`X`), or have had their pairing Broken (`B`).
96 Any combination of the filter characters may be used.
97 When `*` (All-or-none) is added to the combination, all
98 paths are selected if there is any file that matches
99 other criteria in the comparison; if there is no file
100 that matches other criteria, nothing is selected.
102 --find-copies-harder::
103 For performance reasons, by default, `-C` option finds copies only
104 if the original file of the copy was modified in the same
105 changeset. This flag makes the command
106 inspect unmodified files as candidates for the source of
107 copy. This is a very expensive operation for large
108 projects, so use it with caution. Giving more than one
109 `-C` option has the same effect.
112 -M and -C options require O(n^2) processing time where n
113 is the number of potential rename/copy targets. This
114 option prevents rename/copy detection from running if
115 the number of rename/copy targets exceeds the specified
119 Look for differences that contain the change in <string>.
122 When -S finds a change, show all the changes in that
123 changeset, not just the files that contain the change
127 Make the <string> not a plain string but an extended POSIX
131 Output the patch in the order specified in the
132 <orderfile>, which has one shell glob pattern per line.
135 Swap two inputs; that is, show differences from index or
136 on-disk file to tree contents.
139 Treat all files as text.
142 Shorthand for "--text".
144 --ignore-space-at-eol::
145 Ignore changes in white spaces at EOL.
147 --ignore-space-change::
148 Ignore changes in amount of white space. This ignores white
149 space at line end, and consider all other sequences of one or
150 more white space characters to be equivalent.
153 Shorthand for "--ignore-space-change".
156 Ignore white space when comparing lines. This ignores
157 difference even if one line has white space where the other
161 Shorthand for "--ignore-all-space".
164 Make the program exit with codes similar to diff(1).
165 That is, it exits with 1 if there were differences and
166 0 means no differences.
169 Disable all output of the program. Implies --exit-code.
172 Allow an external diff helper to be executed. If you set an
173 external diff driver with gitlink:gitattributes(5), you need
174 to use this option with gitlink:git-log(1) and friends.
177 Disallow external diff drivers.
