Implies "-p". + +--raw:: + Generate the raw format. + +--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". + +-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 white spaces at EOL. + +--ignore-space-change:: + Ignore changes in amount of white space. This ignores white + space at line end, and consider all other sequences of one or + more white space characters to be equivalent. + +-b:: + Shorthand for "--ignore-space-change". + +--ignore-all-space:: + Ignore white space when comparing lines. This ignores + difference even if one line has white space 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]. |
