By default, as much space as necessary will be used for the filename part, and the rest for the graph part\&.

The width of the filename part can be limited by giving another width <name\-width> after a comma\&. The width of the graph part can be limited by using \-\-stat\-graph\-width=<width> (affects all commands generating a stat graph) or by setting diff\&.statGraphWidth=<width> (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\&. .sp These parameters can also be set individually with \-\-stat\-width=<width>, \-\-stat\-name\-width=<name\-width> and \-\-stat\-count=<count>\&. .RE .PP \-\-numstat .RS 4 Similar to \-\-stat, but shows number of added and deleted lines in decimal notation and pathname without abbreviation, to make it more machine friendly\&.

The following parameters are available: .PP changes .RS 4 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\&. .RE .PP lines .RS 4 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\&. .RE .PP files .RS 4 Compute the dirstat numbers by counting the number of files changed\&.

This is the computationally cheapest \-\-dirstat behavior, since it does not have to look at the file contents at all\&. .RE .PP cumulative .RS 4 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%\&.

When \-\-submodule or \-\-submodule=log is given, the \fIlog\fR format is used\&. This format lists the commits in the range like \fBgit-submodule\fR(1) summary does\&. Omitting the \-\-submodule option or specifying \-\-submodule=short, uses the \fIshort\fR format\&. This format just shows the names of the commits at the beginning and end of the range\&.

This serves two purposes: .sp 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)\&. .sp 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\(cqs size are eligible for being picked up as a possible source of a rename to another file\&. .RE .PP \-M[<n>], \-\-find\-renames[=<n>] .RS 4 If generating diffs, detect and report renames for each commit\&. For following files across renames while traversing history, see \-\-follow\&. If n is specified, it is a threshold on the similarity index (i\&.e\&. amount of addition/deletions compared to the file\(cqs size)\&. For example, \-M90% means Git should consider a delete/add pair to be a rename if more than 90% of the file hasn\(cqt 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%\&.

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\&. .RE .PP \-D, \-\-irreversible\-delete .RS 4 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 lack enough information to apply such a patch in reverse, even manually, hence the name of the option\&. .sp When used together with \-B, omit also the preimage in the deletion part of a delete/create pair\&. .RE .PP \-l<num> .RS 4 The \-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\&. .RE .PP \-\-diff\-filter=[(A|C|D|M|R|T|U|X|B)\&...[*]] .RS 4 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\&.

For this reason, textconv filters are enabled by default only for \fBgit-diff\fR(1) and \fBgit-log\fR(1), but not for \fBgit-format-patch\fR(1) or diff plumbing commands\&. .RE .PP \-\-ignore\-submodules[=<when>] .RS 4 Ignore changes to submodules in the diff generation\&. <when> can be 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 \fIignore\fR option in \fBgit-config\fR(1) or \fBgitmodules\fR(4)\&. 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)\&.

You can customize the creation of such patches via the GIT_EXTERNAL_DIFF and the GIT_DIFF_OPTS environment variables\&. .sp What the \-p option produces is slightly different from the traditional diff format: .sp .RS 4 .ie n \{\ \h'-04' 1.\h'+01'\c .\} .el \{\ .sp -1 .IP " 1." 4.2 .\} It is preceded with a "git diff" header that looks like this: .sp .if n \{\ .RS 4 .\} .nf diff \-\-git a/file1 b/file2 .fi .if n \{\ .RE .\} .sp The a/ and b/ filenames are the same unless rename/copy is involved\&. Especially, even for a creation or a deletion, /dev/null is \fInot\fR used in place of the a/ or b/ filenames\&. .sp When rename/copy is involved, file1 and file2 show the name of the source file of the rename/copy and the name of the file that rename/copy produces, respectively\&. .RE .sp .RS 4 .ie n \{\ \h'-04' 2.\h'+01'\c .\} .el \{\ .sp -1 .IP " 2." 4.2 .\} It is followed by one or more extended header lines: .sp .if n \{\ .RS 4 .\} .nf old mode <mode> new mode <mode> deleted file mode <mode> new file mode <mode> copy from <path> copy to <path> rename from <path> rename to <path> similarity index <number> dissimilarity index <number> index <hash>\&.\&.<hash> <mode> .fi .if n \{\ .RE .\} .sp File modes are printed as 6\-digit octal numbers including the file type and file permission bits\&. .sp Path names in extended headers do not include the a/ and b/ prefixes\&. .sp The similarity index is the percentage of unchanged lines, and the dissimilarity index is the percentage of changed lines\&. It is a rounded down integer, followed by a percent sign\&. The similarity index value of 100% is thus reserved for two equal files, while 100% dissimilarity means that no line from the old file made it into the new one\&. .sp The index line includes the SHA\-1 checksum before and after the change\&. The <mode> is included if the file mode does not change; otherwise, separate lines indicate the old and the new mode\&. .RE .sp .RS 4 .ie n \{\ \h'-04' 3.\h'+01'\c .\} .el \{\ .sp -1 .IP " 3." 4.2 .\} TAB, LF, double quote and backslash characters in pathnames are represented as \et, \en, \e" and \e\e, respectively\&.
