-u::
Synonym for "-p".
--r::
- Look recursively in subdirectories; this flag does not
- mean anything to commands other than "git-diff-tree";
- other diff commands always look at all the subdirectories.
+-U<n>::
+ Shorthand for "--unified=<n>".
+
+--unified=<n>::
+ Generate diffs with <n> lines of context instead of
+ the usual three. Implies "-p".
+
+--raw::
+ Generate the raw format.
+
+--patch-with-raw::
+ Synonym for "-p --raw".
+
+--stat[=width[,name-width]]::
+ Generate a diffstat. You can override the default
+ output width for 80-column terminal by "--stat=width".
+ The width of the filename part can be controlled by
+ giving another width to it separated by a comma.
+
+--numstat::
+ Similar to \--stat, but shows number of added and
+ deleted lines in decimal notation and pathname without
+ abbreviation, to make it more machine friendly. For
+ binary files, outputs two `-` instead of saying
+ `0 0`.
+
+--shortstat::
+ Output only the last line of the --stat format containing total
+ number of modified files, as well as number of added and deleted
+ lines.
+
+--summary::
+ Output a condensed summary of extended header information
+ such as creations, renames and mode changes.
+
+--patch-with-stat::
+ Synonym for "-p --stat".
-z::
- \0 line termination on output
+ NUL-line termination on output. This affects the --raw
+ output field terminator. Also output from commands such
+ as "git-log" will be delimited with NUL between commits.
--name-only::
Show only names of changed files.
---name-only-z::
- Same as --name-only, but terminate lines with NUL.
+--name-status::
+ Show only names and status of changed files.
+
+--color::
+ Show colored diff.
+
+--no-color::
+ Turn off colored diff, even when the configuration file
+ gives the default to color output.
+
+--color-words::
+ Show colored word diff, i.e. color words which have changed.
+
+--no-renames::
+ Turn off rename detection, even when the configuration
+ file gives the default to do so.
+
+--check::
+ Warn if changes introduce trailing whitespace
+ or an indent that uses a space before a tab.
+
+--full-index::
+ Instead of the first handful characters, show full
+ object name of pre- and post-image blob on the "index"
+ line when generating a patch format output.
+
+--binary::
+ In addition to --full-index, output "binary diff" that
+ can be applied with "git apply".
+
+--abbrev[=<n>]::
+ Instead of showing the full 40-byte hexadecimal object
+ name in diff-raw format output and diff-tree header
+ lines, show only handful hexdigits prefix. This is
+ independent of --full-index option above, which controls
+ the diff-patch output format. Non default number of
+ digits can be specified with --abbrev=<n>.
-B::
Break complete rewrite changes into pairs of delete and create.
Detect renames.
-C::
- Detect copies as well as renames.
+ Detect copies as well as renames. See also `--find-copies-harder`.
+
+--diff-filter=[ACDMRTUXB*]::
+ Select only files that are Added (`A`), Copied (`C`),
+ Deleted (`D`), Modified (`M`), Renamed (`R`), have their
+ type (mode) changed (`T`), are Unmerged (`U`), are
+ Unknown (`X`), or have had their pairing Broken (`B`).
+ Any combination of the filter characters may be used.
+ When `*` (All-or-none) is added to the combination, all
+ paths are selected if there is any file that matches
+ other criteria in the comparison; if there is no file
+ that matches other criteria, nothing is selected.
--find-copies-harder::
- By default, -C option finds copies only if the original
- file of the copy was modified in the same changeset for
- performance reasons. This flag makes the command
+ For performance reasons, by default, `-C` option finds copies only
+ if the original file of the copy was modified in the same
+ changeset. This flag makes the command
inspect unmodified files as candidates for the source of
copy. This is a very expensive operation for large
- projects, so use it with caution.
+ projects, so use it with caution. Giving more than one
+ `-C` option has the same effect.
-l<num>::
-M and -C options require O(n^2) processing time where n
- in the number of potential rename/copy targets. This
+ is the number of potential rename/copy targets. This
option prevents rename/copy detection from running if
- the number of rename/copy targets exceed the specified
+ the number of rename/copy targets exceeds the specified
number.
-S<string>::
- Look for differences that contains the change in <string>.
+ Look for differences that contain the change in <string>.
--pickaxe-all::
When -S finds a change, show all the changes in that
- changeset, not just the files that contains the change
+ changeset, not just the files that contain the change
in <string>.
+--pickaxe-regex::
+ Make the <string> not a plain string but an extended POSIX
+ regex to match.
+
-O<orderfile>::
Output the patch in the order specified in the
<orderfile>, which has one shell glob pattern per line.
-R::
- Swap two inputs; that is, show differences from cache or
+ Swap two inputs; that is, show differences from index or
on-disk file to tree contents.
+--text::
+ Treat all files as text.
+
+-a::
+ Shorthand for "--text".
+
+--ignore-space-at-eol::
+ Ignore changes in white spaces at EOL.
+
+--ignore-space-change::
+ Ignore changes in amount of white space. This ignores white
+ space at line end, and consider all other sequences of one or
+ more white space characters to be equivalent.
+
+-b::
+ Shorthand for "--ignore-space-change".
+
+--ignore-all-space::
+ Ignore white space when comparing lines. This ignores
+ difference even if one line has white space where the other
+ line has none.
+
+-w::
+ Shorthand for "--ignore-all-space".
+
+--exit-code::
+ Make the program exit with codes similar to diff(1).
+ That is, it exits with 1 if there were differences and
+ 0 means no differences.
+
+--quiet::
+ Disable all output of the program. Implies --exit-code.
+
+--ext-diff::
+ Allow an external diff helper to be executed. If you set an
+ external diff driver with gitlink:gitattributes(5), you need
+ to use this option with gitlink:git-log(1) and friends.
+
+--no-ext-diff::
+ Disallow external diff drivers.
