// Please don't remove this comment as asciidoc behaves badly when
// the first non-empty line is ifdef/ifndef. The symptom is that
// without this comment the <git-diff-core> attribute conditionally
// defined below ends up being defined unconditionally.
// Last checked with asciidoc 7.0.2.
ifndef::git-format-patch[]
ifndef::git-diff[]
ifndef::git-log[]
:git-diff-core: 1
endif::git-log[]
endif::git-diff[]
endif::git-format-patch[]
ifdef::git-format-patch[]
-p::
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.
--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.
--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.
-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.
--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 gitlink:gitattributes[5], you need
to use this option with gitlink:git-log[1] and friends.
--no-ext-diff::
Disallow external diff drivers.
For more detailed explanation on these common options, see also
link:diffcore.html[diffcore documentation].
