-u::
Synonym for "-p".
+-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::
- Generate a diffstat.
+--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
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.
Turn off colored diff, even when the configuration file
gives the default to color output.

object name of pre- and post-image blob on the "index"

+ Detect copies as well as renames. See also `--find-copies-harder`.
--diff-filter=[ACDMRTUXB*]::
Select only files that are Added (`A`), Copied (`C`),
that matches other criteria, nothing is selected.

- For performance reasons, by default, -C option finds copies only
- if the original file of the copy was modified in the same
+ For performance reasons, by default, `-C` option finds copies only
+ if the original file of the copy was modified in the same

-l<num>::
-M and -C options require O(n^2) processing time where n
-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

+ 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
