--patience::
Generate a diff using the "patience diff" algorithm.
---stat[=width[,name-width]]::
+--stat[=<width>[,<name-width>[,<count>]]]::
Generate a diffstat. You can override the default
- output width for 80-column terminal by `--stat=width`.
+ 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.
+ By giving a third parameter `<count>`, you can limit the
+ output to the first `<count>` lines, followed by
+ `...` if there are more.
--numstat::
Similar to `\--stat`, but shows number of added and
number of modified files, as well as number of added and deleted
lines.
---dirstat[=limit]::
+--dirstat[=<limit>]::
Output the distribution of relative amount of changes (number of lines added or
removed) for each sub-directory. Directories with changes below
a cut-off percent (3% by default) are not shown. The cut-off percent
- can be set with `--dirstat=limit`. Changes in a child directory is not
+ can be set with `--dirstat=<limit>`. Changes in a child directory are not
counted for the parent directory, unless `--cumulative` is used.
++
+Note that the `--dirstat` option computes the changes while ignoring
+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.
---dirstat-by-file[=limit]::
+--dirstat-by-file[=<limit>]::
Same as `--dirstat`, but counts changed files instead of lines.
--summary::
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:
+
another file.
-M[<n>]::
+--find-renames[=<n>]::
ifndef::git-log[]
Detect renames.
endif::git-log[]
hasn't changed.
-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>`.
-ifndef::git-format-patch[]
---diff-filter=[ACDMRTUXB*]::
- 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 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.
-endif::git-format-patch[]
-
--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
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` nor `git apply`; this is
+ solely for people who want to just concentrate on reviewing the
+ text after the change. In addition, the output obviously lack
+ 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 require O(n^2) processing time where n
is the number of potential rename/copy targets. This
number.
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.
+
-S<string>::
Look for differences that introduce or remove an instance of
<string>. Note that this is different than the string simply
appearing in diff output; see the 'pickaxe' entry in
linkgit:gitdiffcore[7] for more details.
+-G<regex>::
+ Look for differences whose added or removed line matches
+ the given <regex>.
+
--pickaxe-all::
- When `-S` finds a change, show all the changes in that
+ When `-S` or `-G` finds a change, show all the changes in that
changeset, not just the files that contain the change
in <string>.
--ignore-submodules[=<when>]::
Ignore changes to submodules in the diff generation. <when> can be
- either "untracked", "dirty" or "all", which is the default. When
+ either "none", "untracked", "dirty" or "all", which 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,
