The new option --ignore-submodules can now be used to ignore changes in submodules. Why? Sometimes it is not interesting when a submodule changed. For example, when reordering some commits in the superproject, a dirty submodule is usually totally uninteresting. So we will use this option in git-rebase to test for a dirty working tree.

Generate patches without diffstat.
|
|
endif::git-format-patch[]
|
|
|
|
ifndef::git-format-patch[]
|
|
-p::
|
|
Generate patch (see section on generating patches).
|
|
{git-diff? This is the default.}
|
|
endif::git-format-patch[]
|
|
|
|
-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.
|
|
{git-diff-core? This is the default.}
|
|
|
|
--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.
|
|
|
|
--dirstat[=limit]::
|
|
Output only the sub-directories that are impacted by a diff,
|
|
and to what degree they are impacted. You can override the
|
|
default cut-off in percent (3) by "--dirstat=limit". If you
|
|
want to enable "cumulative" directory statistics, you can use
|
|
the "--cumulative" flag, which adds up percentages recursively
|
|
even when they have been already reported for a sub-directory.
|
|
|
|
--summary::
|
|
Output a condensed summary of extended header information
|
|
such as creations, renames and mode changes.
|
|
|
|
--patch-with-stat::
|
|
Synonym for "-p --stat".
|
|
{git-format-patch? This is the default.}
|
|
|
|
-z::
|
|
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-status::
|
|
Show only names and status of changed files. See the description
|
|
of the `--diff-filter` option on what the status letters mean.
|
|
|
|
--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. Exits with
|
|
non-zero status if problems are found. Not compatible with
|
|
--exit-code.
|
|
|
|
--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.
|
|
|
|
-M::
|
|
Detect renames.
|
|
|
|
-C::
|
|
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::
|
|
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. Giving more than one
|
|
`-C` option has the same effect.
|
|
|
|
-l<num>::
|
|
-M and -C options require O(n^2) processing time where n
|
|
is the number of potential rename/copy targets. This
|
|
option prevents rename/copy detection from running if
|
|
the number of rename/copy targets exceeds the specified
|
|
number.
|
|
|
|
-S<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 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 index or
|
|
on-disk file to tree contents.
|
|
|
|
--relative[=<path>]::
|
|
When run from a subdirectory of the project, it can be
|
|
told to exclude changes outside the directory and show
|
|
pathnames relative to it with this option. When you are
|
|
not in a subdirectory (e.g. in a bare repository), you
|
|
can name which subdirectory to make the output relative
|
|
to by giving a <path> as an argument.
|
|
|
|
--text::
|
|
Treat all files as text.
|
|
|
|
-a::
|
|
Shorthand for "--text".
|
|
|
|
--ignore-space-at-eol::
|
|
Ignore changes in whitespace at EOL.
|
|
|
|
--ignore-space-change::
|
|
Ignore changes in amount of whitespace. This ignores whitespace
|
|
at line end, and considers all other sequences of one or
|
|
more whitespace characters to be equivalent.
|
|
|
|
-b::
|
|
Shorthand for "--ignore-space-change".
|
|
|
|
--ignore-all-space::
|
|
Ignore whitespace when comparing lines. This ignores
|
|
differences even if one line has whitespace 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 linkgit:gitattributes[5], you need
|
|
to use this option with linkgit:git-log[1] and friends.
|
|
|
|
--no-ext-diff::
|
|
Disallow external diff drivers.
|
|
|
|
--ignore-submodules::
|
|
Ignore changes to submodules in the diff generation.
|
|
|
|
--src-prefix=<prefix>::
|
|
Show the given source prefix instead of "a/".
|
|
|
|
--dst-prefix=<prefix>::
|
|
Show the given destination prefix instead of "b/".
|
|
|
|
--no-prefix::
|
|
Do not show any source or destination prefix.
|
|
