20 Similar to \--stat, but shows number of added and
21 deleted lines in decimal notation and pathname without
2f89543e
JH

JH
75 Instead of showing the full 40-byte hexadecimal object
76 name in diff-raw format output and diff-tree header
89438677 77 lines, show only handful hexdigits prefix. This is
913419fc
JH
78 independent of --full-index option above, which controls
79 the diff-patch output format. Non default number of
80 digits can be specified with --abbrev=<n>.

83 Break complete rewrite changes into pairs of delete and create.
84

JL
91--diff-filter=[ACDMRTUXB*]::
92 Select only files that are Added (`A`), Copied (`C`),
93 Deleted (`D`), Modified (`M`), Renamed (`R`), have their
94 type (mode) changed (`T`), are Unmerged (`U`), are
95 Unknown (`X`), or have had their pairing Broken (`B`).
96 Any combination of the filter characters may be used.
97 When `*` (All-or-none) is added to the combination, all
98 paths are selected if there is any file that matches
99 other criteria in the comparison; if there is no file
100 that matches other criteria, nothing is selected.
101
dda2d79a 102--find-copies-harder::
ca6c0970 103 For performance reasons, by default, `-C` option finds copies only
a6080a0a 104 if the original file of the copy was modified in the same
f73ae1fc 105 changeset. This flag makes the command
dda2d79a
JH
106 inspect unmodified files as candidates for the source of
107 copy. This is a very expensive operation for large
ca6c0970
JS
108 projects, so use it with caution. Giving more than one
109 `-C` option has the same effect.

8082d8d3
JH
111-l<num>::
112 -M and -C options require O(n^2) processing time where n
f73ae1fc 113 is the number of potential rename/copy targets. This
8082d8d3 114 option prevents rename/copy detection from running if
f73ae1fc 115 the number of rename/copy targets exceeds the specified
8082d8d3
JH
116 number.
117
dda2d79a 118-S<string>::
f73ae1fc 119 Look for differences that contain the change in <string>.
dda2d79a
JH
120
121--pickaxe-all::
122 When -S finds a change, show all the changes in that
f73ae1fc 123 changeset, not just the files that contain the change
dda2d79a
JH
124 in <string>.
125
d01d8c67
PB
126--pickaxe-regex::
127 Make the <string> not a plain string but an extended POSIX
128 regex to match.
129
dda2d79a
JH
130-O<orderfile>::
131 Output the patch in the order specified in the
132 <orderfile>, which has one shell glob pattern per line.
133
134-R::
5f3aa197 135 Swap two inputs; that is, show differences from index or
dda2d79a
JH
136 on-disk file to tree contents.
137
d507bb15
SF
138--text::
139 Treat all files as text.
140

JH
144--ignore-space-at-eol::
145 Ignore changes in white spaces at EOL.
146
8ebe185b
JN
147--ignore-space-change::
148 Ignore changes in amount of white space. This ignores white
149 space at line end, and consider all other sequences of one or
150 more white space characters to be equivalent.
151
152-b::
153 Shorthand for "--ignore-space-change".
154
155--ignore-all-space::
156 Ignore white space when comparing lines. This ignores
157 difference even if one line has white space where the other
158 line has none.
159
160-w::
161 Shorthand for "--ignore-all-space".
162
41bbf9d5
AR
163--exit-code::
164 Make the program exit with codes similar to diff(1).
165 That is, it exits with 1 if there were differences and
166 0 means no differences.
167
2a18c266
AR
168--quiet::
169 Disable all output of the program. Implies --exit-code.
