`--no-patch`::
|

Suppress all output from the diff machinery. Useful for

commands like `git show` that show the patch by default to
|

squelch their output, or to cancel the effect of options like
|
||||
`--patch`, `--stat` earlier on the command line in an alias.

endif::git-format-patch[]

-m::
|
||||
Show diffs for merge commits in the default format. This is
|
||||
similar to `--diff-merges=on`, except `-m` will
|
||||
produce no output unless `-p` is given as well.
|
||||
|
||||
-c::
|
||||
Produce combined diff output for merge commits.
|
||||
Shortcut for `--diff-merges=combined -p`.
|
||||
|
||||
--cc::
|
||||
Produce dense combined diff output for merge commits.
|
||||
Shortcut for `--diff-merges=dense-combined -p`.
|
||||
|
||||
--dd::
|
||||
Produce diff with respect to first parent for both merge and
|
||||
regular commits.
|
||||
Shortcut for `--diff-merges=first-parent -p`.
|
||||
|
||||
--remerge-diff::
|
||||
Produce remerge-diff output for merge commits.
|
||||
Shortcut for `--diff-merges=remerge -p`.
|
||||
|
||||
--no-diff-merges::
|
||||
Synonym for `--diff-merges=off`.
|
||||
|
||||
--diff-merges=<format>::
|
||||
Specify diff format to be used for merge commits. Default is
|
||||
{diff-merges-default} unless `--first-parent` is in use, in
|
||||
which case `first-parent` is the default.
|
||||
+
|
||||
The following formats are supported:
|
||||
+
|
||||
--
|
||||
off, none::
|
||||
Disable output of diffs for merge commits. Useful to override
|
||||
implied value.
|
||||
|
||||
on, m::
|
||||
Make diff output for merge commits to be shown in the default
|
||||
format. The default format can be changed using
|
||||
`log.diffMerges` configuration variable, whose default value
|
||||
is `separate`.
|
||||
|
||||
first-parent, 1::
|
||||
Show full diff with respect to first parent. This is the same
|
||||
format as `--patch` produces for non-merge commits.
|
||||
|
||||
separate::
|
||||
Show full diff with respect to each of parents.
|
||||
Separate log entry and diff is generated for each parent.
|
||||
|
||||
combined, c::
|
||||
Show differences from each of the parents to the merge
|
||||
result simultaneously instead of showing pairwise diff between
|
||||
a parent and the result one at a time. Furthermore, it lists
|
||||
only files which were modified from all parents.
|
||||
|
||||
dense-combined, cc::
|
||||
Further compress output produced by `--diff-merges=combined`
|
||||
by omitting uninteresting hunks whose contents in the parents
|
||||
have only two variants and the merge result picks one of them
|
||||
without modification.
|
||||
|
||||
remerge, r::
|
||||
Remerge two-parent merge commits to create a temporary tree
|
||||
object--potentially containing files with conflict markers
|
||||
and such. A diff is then shown between that temporary tree
|
||||
and the actual merge commit.
|
||||
+
|
||||
The output emitted when this option is used is subject to change, and
|
||||
so is its interaction with other options (unless explicitly
|
||||
documented).
|
||||
--
|
||||
|
||||
--combined-all-paths::
|
||||
Cause combined diffs (used for merge commits) to
|
||||
list the name of the file from all parents. It thus only has
|
||||
effect when `--diff-merges=[dense-]combined` is in use, and
|
||||
is likely only useful if filename changes are detected (i.e.
|
||||
when either rename or copy detection have been requested).
|
||||
endif::git-log[]
|
||||
|
||||
`-U<n>`::
|
||||
`--unified=<n>`::
|
||||
Generate diffs with _<n>_ lines of context instead of
|
||||
the usual three.
|
||||
ifndef::git-format-patch[]
|
||||
Implies `--patch`.
|
||||
endif::git-format-patch[]
|
||||
|
||||
`--output=<file>`::
|
||||
Output to a specific file instead of stdout.
|
||||
|
||||
`--output-indicator-new=<char>`::
|
||||
`--output-indicator-old=<char>`::
|
||||
`--output-indicator-context=<char>`::
|
||||
Specify the character used to indicate new, old or context
|
||||
lines in the generated patch. Normally they are `+`, `-` and
|
||||
' ' respectively.
|
||||
|
||||
ifndef::git-format-patch[]
|
||||
`--raw`::
|
||||
ifndef::git-log[]
|
||||
Generate the diff in raw format.
|
||||
ifdef::git-diff-core[]
|
||||
This is the default.
|
||||
endif::git-diff-core[]
|
||||
endif::git-log[]
|
||||
ifdef::git-log[]
|
||||
For each commit, show a summary of changes using the raw diff
|
||||
format. See the "RAW OUTPUT FORMAT" section of
|
||||
linkgit:git-diff[1]. This is different from showing the log
|
||||
itself in raw format, which you can achieve with
|
||||
`--format=raw`.
|
||||
endif::git-log[]
|
||||
endif::git-format-patch[]
|
||||
|
||||
ifndef::git-format-patch[]
|
||||
`--patch-with-raw`::
|
||||
Synonym for `-p --raw`.
|
||||
endif::git-format-patch[]
|
||||
|
||||
ifdef::git-log[]
|
||||
`-t`::
|
||||
Show the tree objects in the diff output.
|
||||
endif::git-log[]
|
||||
|
||||
`--indent-heuristic`::
|
||||
Enable the heuristic that shifts diff hunk boundaries to make patches
|
||||
easier to read. This is the default.
|
||||
|
||||
`--no-indent-heuristic`::
|
||||
Disable the indent heuristic.
|
||||
|
||||
`--minimal`::
|
||||
Spend extra time to make sure the smallest possible
|
||||
diff is produced.
|
||||
|
||||
`--patience`::
|
||||
Generate a diff using the "patience diff" algorithm.
|
||||
|
||||
`--histogram`::
|
||||
Generate a diff using the "histogram diff" algorithm.
|
||||
|
||||
`--anchored=<text>`::
|
||||
Generate a diff using the "anchored diff" algorithm.
|
||||
+
|
||||
This option may be specified more than once.
|
||||
+
|
||||
If a line exists in both the source and destination, exists only once,
|
||||
and starts with _<text>_, this algorithm attempts to prevent it from
|
||||
appearing as a deletion or addition in the output. It uses the "patience
|
||||
diff" algorithm internally.
|
||||
|
||||
`--diff-algorithm=(patience|minimal|histogram|myers)`::
|
||||
Choose a diff algorithm. The variants are as follows:
|
||||
+
|
||||
--
|
||||
`default`;;
|
||||
`myers`;;
|
||||
The basic greedy diff algorithm. Currently, this is the default.
|
||||
`minimal`;;
|
||||
Spend extra time to make sure the smallest possible diff is
|
||||
produced.
|
||||
`patience`;;
|
||||
Use "patience diff" algorithm when generating patches.
|
||||
`histogram`;;
|
||||
This algorithm extends the patience algorithm to "support
|
||||
low-occurrence common elements".
|
||||
--
|
||||
+
|
||||
For instance, if you configured the `diff.algorithm` variable to a
|
||||
non-default value and want to use the default one, then you
|
||||
have to use `--diff-algorithm=default` option.
|
||||
|
||||
`--stat[=<width>[,<name-width>[,<count>]]]`::
|
||||
Generate a diffstat. By default, as much space as necessary
|
||||
will be used for the filename part, and the rest for the graph
|
||||
part. Maximum width defaults to terminal width, or 80 columns
|
||||
if not connected to a terminal, and can be overridden by
|
||||
_<width>_. The width of the filename part can be limited by
|
||||
giving another width _<name-width>_ after a comma or by setting
|
||||
`diff.statNameWidth=<name-width>`. The width of the graph part can be
|
||||
limited by using `--stat-graph-width=<graph-width>` or by setting
|
||||
`diff.statGraphWidth=<graph-width>`. Using `--stat` or
|
||||
`--stat-graph-width` affects all commands generating a stat graph,
|
||||
while setting `diff.statNameWidth` or `diff.statGraphWidth`
|
||||
does not affect `git format-patch`.
|
||||
By giving a third parameter _<count>_, you can limit the output to
|
||||
the first _<count>_ lines, followed by `...` if there are more.
|
||||
+
|
||||
These parameters can also be set individually with `--stat-width=<width>`,
|
||||
`--stat-name-width=<name-width>` and `--stat-count=<count>`.
|
||||
|
||||
`--compact-summary`::
|
||||
Output a condensed summary of extended header information such
|
||||
as file creations or deletions ("new" or "gone", optionally `+l`
|
||||
if it's a symlink) and mode changes (`+x` or `-x` for adding
|
||||
or removing executable bit respectively) in diffstat. The
|
||||
information is put between the filename part and the graph
|
||||
part. Implies `--stat`.
|
||||
|
||||
`--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.
|
||||
|
||||
`-X [<param>,...]`::
|
||||
`--dirstat[=<param>,...]`::
|
||||
Output the distribution of relative amount of changes for each
|
||||
sub-directory. The behavior of `--dirstat` can be customized by
|
||||
passing it a comma separated list of parameters.
|
||||
The defaults are controlled by the `diff.dirstat` configuration
|
||||
variable (see linkgit:git-config[1]).
|
||||
The following parameters are available:
|
||||
+
|
||||
--
|
||||
`changes`;;
|
||||
Compute the dirstat numbers by counting the lines that have been
|
||||
removed from the source, or added to the destination. This ignores
|
||||
the amount of pure code movements within a file. In other words,
|
||||
rearranging lines in a file is not counted as much as other changes.
|
||||
This is the default behavior when no parameter is given.
|
||||
`lines`;;
|
||||
Compute the dirstat numbers by doing the regular line-based diff
|
||||
analysis, and summing the removed/added line counts. (For binary
|
||||
files, count 64-byte chunks instead, since binary files have no
|
||||
natural concept of lines). This is a more expensive `--dirstat`
|
||||
behavior than the `changes` behavior, but it does count rearranged
|
||||
lines within a file as much as other changes. The resulting output
|
||||
is consistent with what you get from the other `--*stat` options.
|
||||
`files`;;
|
||||
Compute the dirstat numbers by counting the number of files changed.
|
||||
Each changed file counts equally in the dirstat analysis. This is
|
||||
the computationally cheapest `--dirstat` behavior, since it does
|
||||
not have to look at the file contents at all.
|
||||
`cumulative`;;
|
||||
Count changes in a child directory for the parent directory as well.
|
||||
Note that when using `cumulative`, the sum of the percentages
|
||||
reported may exceed 100%. The default (non-cumulative) behavior can
|
||||
be specified with the `noncumulative` parameter.
|
||||
_<limit>_;;
|
||||
An integer parameter specifies a cut-off percent (3% by default).
|
||||
Directories contributing less than this percentage of the changes
|
||||
are not shown in the output.
|
||||
--
|
||||
+
|
||||
Example: The following will count changed files, while ignoring
|
||||
directories with less than 10% of the total amount of changed files,
|
||||
and accumulating child directory counts in the parent directories:
|
||||
`--dirstat=files,10,cumulative`.
|
||||
|
||||
`--cumulative`::
|
||||
Synonym for `--dirstat=cumulative`.
|
||||
|
||||
`--dirstat-by-file[=<param>,...]`::
|
||||
Synonym for `--dirstat=files,<param>,...`.
|
||||
|
||||
`--summary`::
|
||||
Output a condensed summary of extended header information
|
||||
such as creations, renames and mode changes.
|
||||
|
||||
ifndef::git-format-patch[]
|
||||
`--patch-with-stat`::
|
||||
Synonym for `-p --stat`.
|
||||
endif::git-format-patch[]
|
||||
|
||||
ifndef::git-format-patch[]
|
||||
|
||||
`-z`::
|
||||
ifdef::git-log[]
|
||||
Separate the commits with __NUL__s instead of newlines.
|
||||
+
|
||||
Also, when `--raw` or `--numstat` has been given, do not munge
|
||||
pathnames and use __NUL__s as output field terminators.
|
||||
endif::git-log[]
|
||||
ifndef::git-log[]
|
||||
When `--raw`, `--numstat`, `--name-only` or `--name-status` has been
|
||||
given, do not munge pathnames and use NULs as output field terminators.
|
||||
endif::git-log[]
|
||||
+
|
||||
Without this option, pathnames with "unusual" characters are quoted as
|
||||
explained for the configuration variable `core.quotePath` (see
|
||||
linkgit:git-config[1]).
|
||||
|
||||
`--name-only`::
|
||||
Show only the name of each changed file in the post-image tree.
|
||||
The file names are often encoded in UTF-8.
|
||||
For more information see the discussion about encoding in the linkgit:git-log[1]
|
||||
manual page.
|
||||
|
||||
`--name-status`::
|
||||
Show only the name(s) and status of each changed file. See the description
|
||||
of the `--diff-filter` option on what the status letters mean.
|
||||
Just like `--name-only` the file names are often encoded in UTF-8.
|
||||
|
||||
`--submodule[=<format>]`::
|
||||
Specify how differences in submodules are shown. When specifying
|
||||
`--submodule=short` the `short` format is used. This format just
|
||||
shows the names of the commits at the beginning and end of the range.
|
||||
When `--submodule` or `--submodule=log` is specified, the `log`
|
||||
format is used. This format lists the commits in the range like
|
||||
linkgit:git-submodule[1] `summary` does. When `--submodule=diff`
|
||||
is specified, the `diff` format is used. This format shows an
|
||||
inline diff of the changes in the submodule contents between the
|
||||
commit range. Defaults to `diff.submodule` or the `short` format
|
||||
if the config option is unset.
|
||||
|
||||
`--color[=<when>]`::
|
||||
Show colored diff.
|
||||
`--color` (i.e. without `=<when>`) is the same as `--color=always`.
|
||||
_<when>_ can be one of `always`, `never`, or `auto`.
|
||||
ifdef::git-diff[]
|
||||
It can be changed by the `color.ui` and `color.diff`
|
||||
configuration settings.
|
||||
endif::git-diff[]
|
||||
|
||||
`--no-color`::
|
||||
Turn off colored diff.
|
||||
ifdef::git-diff[]
|
||||
This can be used to override configuration settings.
|
||||
endif::git-diff[]
|
||||
It is the same as `--color=never`.
|
||||
|
||||
`--color-moved[=<mode>]`::
|
||||
Moved lines of code are colored differently.
|
||||
ifdef::git-diff[]
|
||||
It can be changed by the `diff.colorMoved` configuration setting.
|
||||
endif::git-diff[]
|
||||
The _<mode>_ defaults to `no` if the option is not given
|
||||
and to `zebra` if the option with no mode is given.
|
||||
The mode must be one of:
|
||||
+
|
||||
--
|
||||
`no`::
|
||||
Moved lines are not highlighted.
|
||||
`default`::
|
||||
Is a synonym for `zebra`. This may change to a more sensible mode
|
||||
in the future.
|
||||
`plain`::
|
||||
Any line that is added in one location and was removed
|
||||
in another location will be colored with `color.diff.newMoved`.
|
||||
Similarly `color.diff.oldMoved` will be used for removed lines
|
||||
that are added somewhere else in the diff. This mode picks up any
|
||||
moved line, but it is not very useful in a review to determine
|
||||
if a block of code was moved without permutation.
|
||||
`blocks`::
|
||||
Blocks of moved text of at least 20 alphanumeric characters
|
||||
are detected greedily. The detected blocks are
|
||||
painted using either the `color.diff.(old|new)Moved` color.
|
||||
Adjacent blocks cannot be told apart.
|
||||
`zebra`::
|
||||
Blocks of moved text are detected as in `blocks` mode. The blocks
|
||||
are painted using either the `color.diff.(old|new)Moved` color or
|
||||
`color.diff.(old|new)MovedAlternative`. The change between
|
||||
the two colors indicates that a new block was detected.
|
||||
`dimmed-zebra`::
|
||||
Similar to `zebra`, but additional dimming of uninteresting parts
|
||||
of moved code is performed. The bordering lines of two adjacent
|
||||
blocks are considered interesting, the rest is uninteresting.
|
||||
`dimmed_zebra` is a deprecated synonym.
|
||||
--
|
||||
|
||||
`--no-color-moved`::
|
||||
Turn off move detection. This can be used to override configuration
|
||||
settings. It is the same as `--color-moved=no`.
|
||||
|
||||
`--color-moved-ws=<mode>,...`::
|
||||
This configures how whitespace is ignored when performing the
|
||||
move detection for `--color-moved`.
|
||||
ifdef::git-diff[]
|
||||
It can be set by the `diff.colorMovedWS` configuration setting.
|
||||
endif::git-diff[]
|
||||
These modes can be given as a comma separated list:
|
||||
+
|
||||
--
|
||||
`no`::
|
||||
Do not ignore whitespace when performing move detection.
|
||||
`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.
|
||||
`ignore-all-space`::
|
||||
Ignore whitespace when comparing lines. This ignores differences
|
||||
even if one line has whitespace where the other line has none.
|
||||
`allow-indentation-change`::
|
||||
Initially ignore any whitespace in the move detection, then
|
||||
group the moved code blocks only into a block if the change in
|
||||
whitespace is the same per line. This is incompatible with the
|
||||
other modes.
|
||||
--
|
||||
|
||||
`--no-color-moved-ws`::
|
||||
Do not ignore whitespace when performing move detection. This can be
|
||||
used to override configuration settings. It is the same as
|
||||
`--color-moved-ws=no`.
|
||||
|
||||
`--word-diff[=<mode>]`::
|
||||
By default, words are delimited by whitespace; see
|
||||
`--word-diff-regex` below. The _<mode>_ defaults to `plain`, and
|
||||
must be one of:
|
||||
+
|
||||
--
|
||||
`color`::
|
||||
Highlight changed words using only colors. Implies `--color`.
|
||||
`plain`::
|
||||
Show words as ++[-removed-]++ and ++{+added+}++. Makes no
|
||||
attempts to escape the delimiters if they appear in the input,
|
||||
so the output may be ambiguous.
|
||||
`porcelain`::
|
||||
Use a special line-based format intended for script
|
||||
consumption. Added/removed/unchanged runs are printed in the
|
||||
usual unified diff format, starting with a `+`/`-`/` `
|
||||
character at the beginning of the line and extending to the
|
||||
end of the line. Newlines in the input are represented by a
|
||||
tilde `~` on a line of its own.
|
||||
`none`::
|
||||
Disable word diff again.
|
||||
--
|
||||
+
|
||||
Note that despite the name of the first mode, color is used to
|
||||
highlight the changed parts in all modes if enabled.
|
||||
|
||||
`--word-diff-regex=<regex>`::
|
||||
Use _<regex>_ to decide what a word is, instead of considering
|
||||
runs of non-whitespace to be a word. Also implies
|
||||
`--word-diff` unless it was already enabled.
|
||||
+
|
||||
Every non-overlapping match of the
|
||||
_<regex>_ is considered a word. Anything between these matches is
|
||||
considered whitespace and ignored(!) for the purposes of finding
|
||||
differences. You may want to append `|[^[:space:]]` to your regular
|
||||
expression to make sure that it matches all non-whitespace characters.
|
||||
A match that contains a newline is silently truncated(!) at the
|
||||
newline.
|
||||
+
|
||||
For example, `--word-diff-regex=.` will treat each character as a word
|
||||
and, correspondingly, show differences character by character.
|
||||
+
|
||||
The regex can also be set via a diff driver or configuration option, see
|
||||
linkgit:gitattributes[5] or linkgit:git-config[1]. Giving it explicitly
|
||||
overrides any diff driver or configuration setting. Diff drivers
|
||||
override configuration settings.
|
||||
|
||||
`--color-words[=<regex>]`::
|
||||
Equivalent to `--word-diff=color` plus (if a regex was
|
||||
specified) `--word-diff-regex=<regex>`.
|
||||
endif::git-format-patch[]
|
||||
|
||||
`--no-renames`::
|
||||
Turn off rename detection, even when the configuration
|
||||
file gives the default to do so.
|
||||
|
||||
`--[no-]rename-empty`::
|
||||
Whether to use empty blobs as rename source.
|
||||
|
||||
ifndef::git-format-patch[]
|
||||
`--check`::
|
||||
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 consist solely of whitespaces) and a space character
|
||||
that is immediately followed by a tab character inside the
|
||||
initial indent of the line are considered whitespace errors.
|
||||
Exits with non-zero status if problems are found. Not compatible
|
||||
with `--exit-code`.
|
||||
|
||||
`--ws-error-highlight=<kind>`::
|
||||
Highlight whitespace errors in the `context`, `old` or `new`
|
||||
lines of the diff. Multiple values are separated by comma,
|
||||
`none` resets previous values, `default` reset the list to
|
||||
`new` and `all` is a shorthand for `old,new,context`. When
|
||||
this option is not given, and the configuration variable
|
||||
`diff.wsErrorHighlight` is not set, only whitespace errors in
|
||||
`new` lines are highlighted. The whitespace errors are colored
|
||||
with `color.diff.whitespace`.
|
||||
|
||||
endif::git-format-patch[]
|
||||
|
||||
`--full-index`::
|
||||
Instead of the first handful of characters, show the full
|
||||
pre- and post-image blob object names on the "index"
|
||||
line when generating patch format output.
|
||||
|
||||
`--binary`::
|
||||
In addition to `--full-index`, output a binary diff that
|
||||
can be applied with `git-apply`.
|
||||
ifndef::git-format-patch[]
|
||||
Implies `--patch`.
|
||||
endif::git-format-patch[]
|
||||
|
||||
`--abbrev[=<n>]`::
|
||||
Instead of showing the full 40-byte hexadecimal object
|
||||
name in diff-raw format output and diff-tree header
|
||||
lines, show the shortest prefix that is at least _<n>_
|
||||
hexdigits long that uniquely refers the object.
|
||||
In diff-patch output format, `--full-index` takes higher
|
||||
precedence, i.e. if `--full-index` is specified, full blob
|
||||
names will be shown regardless of `--abbrev`.
|
||||
Non default number of digits can be specified with `--abbrev=<n>`.
|
||||
|
||||
`-B[<n>][/<m>]`::
|
||||
`--break-rewrites[=[<n>][/<m>]]`::
|
||||
Break complete rewrite changes into pairs of delete and
|
||||
create. This serves two purposes:
|
||||
+
|
||||
It affects the way a change that amounts to a total rewrite of a file
|
||||
not as a series of deletion and insertion mixed together with a very
|
||||
few lines that happen to match textually as the context, but as a
|
||||
single deletion of everything old followed by a single insertion of
|
||||
everything new, and the number _<m>_ controls this aspect of the `-B`
|
||||
option (defaults to 60%). `-B/70%` specifies that less than 30% of the
|
||||
original should remain in the result for Git to consider it a total
|
||||
rewrite (i.e. otherwise the resulting patch will be a series of
|
||||
deletion and insertion mixed together with context lines).
|
||||
+
|
||||
When used with `-M`, a totally-rewritten file is also considered as the
|
||||
source of a rename (usually `-M` only considers a file that disappeared
|
||||
as the source of a rename), and the number _<n>_ controls this aspect of
|
||||
the `-B` option (defaults to 50%). `-B20%` specifies that a change with
|
||||
addition and deletion compared to 20% or more of the file's size are
|
||||
eligible for being picked up as a possible source of a rename to
|
||||
another file.
|
||||
|
||||
`-M[<n>]`::
|
||||
`--find-renames[=<n>]`::
|
||||
ifndef::git-log[]
|
||||
Detect renames.
|
||||
endif::git-log[]
|
||||
ifdef::git-log[]
|
||||
If generating diffs, detect and report renames for each commit.
|
||||
For following files across renames while traversing history, see
|
||||
`--follow`.
|
||||
endif::git-log[]
|
||||
If _<n>_ is specified, it is a threshold on the similarity
|
||||
index (i.e. amount of addition/deletions compared to the
|
||||
file's size). For example, `-M90%` means Git should consider a
|
||||
delete/add pair to be a rename if more than 90% of the file
|
||||
hasn't changed. Without a `%` sign, the number is to be read as
|
||||
a fraction, with a decimal point before it. I.e., `-M5` becomes
|
||||
0.5, and is thus the same as `-M50%`. Similarly, `-M05` is
|
||||
the same as `-M5%`. To limit detection to exact renames, use
|
||||
`-M100%`. The default similarity index is 50%.
|
||||
|
||||
`-C[<n>]`::
|
||||
`--find-copies[=<n>]`::
|
||||
Detect copies as well as renames. See also `--find-copies-harder`.
|
||||
If _<n>_ is specified, it has the same meaning as for `-M<n>`.
|
||||
|
||||
`--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.
|
||||
|
||||
`-D`::
|
||||
`--irreversible-delete`::
|
||||
Omit the preimage for deletes, i.e. print only the header but not
|
||||
the diff between the preimage and `/dev/null`. The resulting patch
|
||||
is not meant to be applied with `patch` or `git apply`; this is
|
||||
solely for people who want to just concentrate on reviewing the
|
||||
text after the change. In addition, the output obviously lacks
|
||||
enough information to apply such a patch in reverse, even manually,
|
||||
hence the name of the option.
|
||||
+
|
||||
When used together with `-B`, omit also the preimage in the deletion part
|
||||
of a delete/create pair.
|
||||
|
||||
`-l<num>`::
|
||||
The `-M` and `-C` options involve some preliminary steps that
|
||||
can detect subsets of renames/copies cheaply, followed by an
|
||||
exhaustive fallback portion that compares all remaining
|
||||
unpaired destinations to all relevant sources. (For renames,
|
||||
only remaining unpaired sources are relevant; for copies, all
|
||||
original sources are relevant.) For N sources and
|
||||
destinations, this exhaustive check is O(N^2). This option
|
||||
prevents the exhaustive portion of rename/copy detection from
|
||||
running if the number of source/destination files involved
|
||||
exceeds the specified number. Defaults to `diff.renameLimit`.
|
||||
Note that a value of 0 is treated as unlimited.
|
||||
|
||||
ifndef::git-format-patch[]
|
||||
`--diff-filter=[(A|C|D|M|R|T|U|X|B)...[*]]`::
|
||||
Select only files that are Added (`A`), Copied (`C`),
|
||||
Deleted (`D`), Modified (`M`), Renamed (`R`), have their
|
||||
type (i.e. regular file, symlink, submodule, ...) changed (`T`),
|
||||
are Unmerged (`U`), are
|
||||
Unknown (`X`), or have had their pairing Broken (`B`).
|
||||
Any combination of the filter characters (including none) can 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.
|
||||
+
|
||||
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, 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
|
||||
the specified _<string>_ (i.e. addition/deletion) in a file.
|
||||
Intended for the scripter's use.
|
||||
+
|
||||
It is useful when you're looking for an exact block of code (like a
|
||||
struct), and want to know the history of that block since it first
|
||||
came into being: use the feature iteratively to feed the interesting
|
||||
block in the preimage back into `-S`, and keep going until you get the
|
||||
very first version of the block.
|
||||
+
|
||||
Binary files are searched as well.
|
||||
|
||||
`-G<regex>`::
|
||||
Look for differences whose patch text contains added/removed
|
||||
lines that match _<regex>_.
|
||||
+
|
||||
To illustrate the difference between `-S<regex>` `--pickaxe-regex` and
|
||||
`-G<regex>`, consider a commit with the following diff in the same
|
||||
file:
|
||||
+
|
||||
----
|
||||
+ return frotz(nitfol, two->ptr, 1, 0);
|
||||
...
|
||||
- hit = frotz(nitfol, mf2.ptr, 1, 0);
|
||||
----
|
||||
+
|
||||
While `git log -G"frotz\(nitfol"` will show this commit, `git log
|
||||
-S"frotz\(nitfol" --pickaxe-regex` will not (because the number of
|
||||
occurrences of that string did not change).
|
||||
+
|
||||
Unless `--text` is supplied patches of binary files without a textconv
|
||||
filter will be ignored.
|
||||
+
|
||||
See the 'pickaxe' entry in linkgit:gitdiffcore[7] for more
|
||||
information.
|
||||
|
||||
`--find-object=<object-id>`::
|
||||
Look for differences that change the number of occurrences of
|
||||
the specified object. Similar to `-S`, just the argument is different
|
||||
in that it doesn't search for a specific string but for a specific
|
||||
object id.
|
||||
+
|
||||
The object can be a blob or a submodule commit. It implies the `-t` option in
|
||||
`git-log` to also find trees.
|
||||
|
||||
`--pickaxe-all`::
|
||||
When `-S` or `-G` finds a change, show all the changes in that
|
||||
changeset, not just the files that contain the change
|
||||
in _<string>_.
|
||||
|
||||
`--pickaxe-regex`::
|
||||
Treat the _<string>_ given to `-S` as an extended POSIX regular
|
||||
expression to match.
|
||||
|
||||
endif::git-format-patch[]
|
||||
|
||||
`-O<orderfile>`::
|
||||
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
|
||||
`fnmatch`(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`".
|
||||
|
||||
`--skip-to=<file>`::
|
||||
`--rotate-to=<file>`::
|
||||
Discard the files before the named _<file>_ from the output
|
||||
(i.e. 'skip to'), or move them to the end of the output
|
||||
(i.e. 'rotate to'). These options were invented primarily for the use
|
||||
of the `git difftool` command, and may not be very useful
|
||||
otherwise.
|
||||
|
||||
ifndef::git-format-patch[]
|
||||
`-R`::
|
||||
Swap two inputs; that is, show differences from index or
|
||||
on-disk file to tree contents.
|
||||
endif::git-format-patch[]
|
||||
|
||||
`--relative[=<path>]`::
|
||||
`--no-relative`::
|
||||
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.
|
||||
`--no-relative` can be used to countermand both `diff.relative` config
|
||||
option and previous `--relative`.
|
||||
|
||||
`-a`::
|
||||
`--text`::
|
||||
Treat all files as text.
|
||||
|
||||
`--ignore-cr-at-eol`::
|
||||
Ignore carriage-return at the end of line when doing a comparison.
|
||||
|
||||
`--ignore-space-at-eol`::
|
||||
Ignore changes in whitespace at EOL.
|
||||
|
||||
`-b`::
|
||||
`--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.
|
||||
|
||||
`-w`::
|
||||
`--ignore-all-space`::
|
||||
Ignore whitespace when comparing lines. This ignores
|
||||
differences even if one line has whitespace where the other
|
||||
line has none.
|
||||
|
||||
`--ignore-blank-lines`::
|
||||
Ignore changes whose lines are all blank.
|
||||
|
||||
|
||||
`-I<regex>`::
|
||||
`--ignore-matching-lines=<regex>`::
|
||||
Ignore changes whose all lines match _<regex>_. This option may
|
||||
be specified more than once.
|
||||
|
||||
`--inter-hunk-context=<number>`::
|
||||
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`::
|
||||
Show whole function as context lines for each change.
|
||||
The function names are determined in the same way as
|
||||
`git diff` works out patch hunk headers (see "Defining a
|
||||
custom hunk-header" in linkgit:gitattributes[5]).
|
||||
|
||||
ifndef::git-format-patch[]
|
||||
ifndef::git-log[]
|
||||
`--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`.
|
||||
Disables execution of external diff helpers whose exit code
|
||||
is not trusted, i.e. their respective configuration option
|
||||
`diff.trustExitCode` or ++diff.++__<driver>__++.trustExitCode++ or
|
||||
environment variable `GIT_EXTERNAL_DIFF_TRUST_EXIT_CODE` is
|
||||
false.
|
||||
endif::git-log[]
|
||||
endif::git-format-patch[]
|
||||
|
||||
`--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.
|
||||
|
||||
`--textconv`::
|
||||
`--no-textconv`::
|
||||
Allow (or disallow) external text conversion filters to be run
|
||||
when comparing binary files. See linkgit:gitattributes[5] for
|
||||
details. Because textconv filters are typically a one-way
|
||||
conversion, the resulting diff is suitable for human
|
||||
consumption, but cannot be applied. For this reason, textconv
|
||||
filters are enabled by default only for linkgit:git-diff[1] and
|
||||
linkgit:git-log[1], but not for linkgit:git-format-patch[1] or
|
||||
diff plumbing commands.
|
||||
|
||||
|
||||
`--ignore-submodules[=(none|untracked|dirty|all)]`::
|
||||
Ignore changes to submodules in the diff generation. `all` is the default.
|
||||
Using `none` will consider the submodule modified when it either contains
|
||||
untracked or modified files or its `HEAD` differs from the commit recorded
|
||||
in the superproject and can be used to override any settings of the
|
||||
`ignore` option in linkgit:git-config[1] or linkgit:gitmodules[5]. When
|
||||
`untracked` is used submodules are not considered dirty when they only
|
||||
contain untracked content (but they are still scanned for modified
|
||||
content). Using `dirty` ignores all changes to the work tree of submodules,
|
||||
only changes to the commits stored in the superproject are shown (this was
|
||||
the behavior until 1.7.0). Using `all` hides all changes to submodules.
|
||||
|
||||
`--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.
|
||||
|
||||
`--default-prefix`::
|
||||
Use the default source and destination prefixes ("a/" and "b/").
|
||||
This overrides configuration variables such as `diff.noprefix`,
|
||||
`diff.srcPrefix`, `diff.dstPrefix`, and `diff.mnemonicPrefix`
|
||||
(see linkgit:git-config[1]).
|
||||
|
||||
`--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.
|
||||
|
||||
For more detailed explanation on these common options, see also
|
||||
linkgit:gitdiffcore[7].
