--no-patch::
Suppress diff output. Useful for commands like `git show` that
show the patch by default, or to cancel the effect of `--patch`.

-U<n>::
--unified=<n>::
Synonym for `-p --raw`.

of the `--diff-filter` option on what the status letters mean.
--submodule[=<format>]::
- Specify how differences in submodules are shown. When `--submodule`
- or `--submodule=log` is given, the 'log' format is used. This format lists
- the commits in the range like linkgit:git-submodule[1] `summary` does.
- Omitting the `--submodule` option or specifying `--submodule=short`,
- uses the 'short' format. This format just shows the names of the commits
- at the beginning and end of the range. Can be tweaked via the
- `diff.submodule` configuration variable.

--check::
- Warn if changes introduce whitespace errors. What are
- considered whitespace errors is controlled by `core.whitespace`
+ Warn if changes introduce conflict markers or whitespace errors.
+ What are considered whitespace errors is controlled by `core.whitespace`
configuration. By default, trailing whitespaces (including
lines that solely consist of whitespaces) and a space character
that is immediately followed by a tab character inside the
lines are highlighted. E.g. `--ws-error-highlight=new,old`
highlights whitespace errors on both deleted and added lines.
`all` can be used as a short-hand for `old,new,context`.
+ The `diff.wsErrorHighlight` configuration variable can be
+ used to specify the default behaviour.

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.
++
+Also, these upper-case letters can be downcased to exclude. E.g.
+`--diff-filter=ad` excludes added and deleted paths.
++
+Note that not all diffs can feature all types. For instance, diffs
+from the index to the working tree can never have Added entries
+(because the set of paths included in the diff is limited by what is in
+the index). Similarly, copied and renamed entries cannot appear if
+detection for those types is disabled.
-S<string>::
Look for differences that change the number of occurrences of
endif::git-format-patch[]
-O<orderfile>::
- Output the patch in the order specified in the
- <orderfile>, which has one shell glob pattern per line.
+ Control the order in which files appear in the output.
This overrides the `diff.orderFile` configuration variable
(see linkgit:git-config[1]). To cancel `diff.orderFile`,
use `-O/dev/null`.
++
+The output order is determined by the order of glob patterns in
+<orderfile>.
+All files with pathnames that match the first pattern are output
+first, all files with pathnames that match the second pattern (but not
+the first) are output next, and so on.
+All files with pathnames that do not match any pattern are output
+last, as if there was an implicit match-all pattern at the end of the
+file.
+If multiple pathnames have the same rank (they match the same pattern
+but no earlier patterns), their output order relative to each other is
+the normal order.
++
+<orderfile> is parsed as follows:
++
+--
+ - Blank lines are ignored, so they can be used as separators for
+ readability.
+
+ - Lines starting with a hash ("`#`") are ignored, so they can be used
+ for comments. Add a backslash ("`\`") to the beginning of the
+ pattern if it starts with a hash.
+
+ - Each other line contains a single pattern.
+--
++
+Patterns have the same syntax and semantics as patterns used for
+fnmantch(3) without the FNM_PATHNAME flag, except a pathname also
+matches a pattern if removing any number of the final pathname
+components matches the pattern. For example, the pattern "`foo*bar`"
+matches "`fooasdfbar`" and "`foo/bar/baz/asdf`" but not "`foobarx`".

-R::
--inter-hunk-context=<lines>::
Show the context between diff hunks, up to the specified number
of lines, thereby fusing hunks that are close to each other.
+ Defaults to `diff.interHunkContext` or 0 if the config option
+ is unset.
-W::
--function-context::
--no-prefix::
Do not show any source or destination prefix.
+--line-prefix=<prefix>::
+ Prepend an additional prefix to every line of output.
+
+--ita-invisible-in-index::
+ By default entries added by "git add -N" appear as an existing
+ empty file in "git diff" and a new file in "git diff --cached".
+ This option makes the entry appear as a new file in "git diff"
+ and non-existent in "git diff --cached". This option could be
+ reverted with `--ita-visible-in-index`. Both options are
+ experimental and could be removed in future.
