10 [(--sort=<key>)...] [--format=<format>] [<pattern>...]
11 [--points-at=<object>]
12 (--merged[=<object>] | --no-merged[=<object>])
13 [--contains[=<object>]] [--no-contains[=<object>]]
14
16 Iterate over all refs that match <pattern> and show them according to
17 the given <format>, after sorting them according to the given set of
18 <key>. If <count> is given, stop after showing that many refs. The
19 interpolated values in <format> can optionally be quoted as string
20 literals in the specified host language allowing their direct
21 evaluation in that language.
22
24 <pattern>...
25 If one or more patterns are given, only refs are shown that match
26 against at least one pattern, either using fnmatch(3) or literally,
27 in the latter case matching completely or from the beginning up to
28 a slash.
29 --count=<count>
31 By default the command shows all refs that match <pattern>. This
32 option makes it stop after showing that many refs.
33 --sort=<key>
35 A field name to sort on. Prefix - to sort in descending order of
36 the value. When unspecified, refname is used. You may use the
37 --sort=<key> option multiple times, in which case the last key
38 becomes the primary key.
39 --format=<format>
41 A string that interpolates %(fieldname) from a ref being shown and
42 the object it points at. If fieldname is prefixed with an asterisk
43 (*) and the ref points at a tag object, use the value for the field
44 in the object which the tag object refers to (instead of the field
45 in the tag object). When unspecified, <format> defaults to
46 %(objectname) SPC %(objecttype) TAB %(refname). It also
47 interpolates %% to %, and %xx where xx are hex digits interpolates
48 to character with hex code xx; for example %00 interpolates to \0
49 (NUL), %09 to \t (TAB) and %0a to \n (LF).
50 --color[=<when>]
52 Respect any colors specified in the --format option. The <when>
53 field must be one of always, never, or auto (if <when> is absent,
54 behave as if always was given).
55 --shell, --perl, --python, --tcl
57 If given, strings that substitute %(fieldname) placeholders are
58 quoted as string literals suitable for the specified host language.
59 This is meant to produce a scriptlet that can directly be `eval`ed.
60 --points-at=<object>
62 Only list refs which points at the given object.
63 --merged[=<object>]
65 Only list refs whose tips are reachable from the specified commit
66 (HEAD if not specified), incompatible with --no-merged.
67 --no-merged[=<object>]
69 Only list refs whose tips are not reachable from the specified
70 commit (HEAD if not specified), incompatible with --merged.
71 --contains[=<object>]
73 Only list refs which contain the specified commit (HEAD if not
74 specified).
75 --no-contains[=<object>]
77 Only list refs which don’t contain the specified commit (HEAD if
78 not specified).
79 --ignore-case
81 Sorting and filtering refs are case insensitive.
82
84 Various values from structured fields in referenced objects can be used
85 to interpolate into the resulting output, or as sort keys.
86 For all objects, the following names can be used:
88 refname
90 The name of the ref (the part after $GIT_DIR/). For a non-ambiguous
91 short name of the ref append :short. The option
92 core.warnAmbiguousRefs is used to select the strict abbreviation
93 mode. If lstrip=<N> (rstrip=<N>) is appended, strips <N>
94 slash-separated path components from the front (back) of the
95 refname (e.g. %(refname:lstrip=2) turns refs/tags/foo into foo and
96 %(refname:rstrip=2) turns refs/tags/foo into refs). If <N> is a
97 negative number, strip as many path components as necessary from
98 the specified end to leave -<N> path components (e.g.
99 %(refname:lstrip=-2) turns refs/tags/foo into tags/foo and
100 %(refname:rstrip=-1) turns refs/tags/foo into refs). When the ref
101 does not have enough components, the result becomes an empty string
102 if stripping with positive <N>, or it becomes the full refname if
103 stripping with negative <N>. Neither is an error.
104 strip can be used as a synonym to lstrip.
106 objecttype
108 The type of the object (blob, tree, commit, tag).
109 objectsize
111 The size of the object (the same as git cat-file -s reports).
112 Append :disk to get the size, in bytes, that the object takes up on
113 disk. See the note about on-disk sizes in the CAVEATS section
114 below.
115 objectname
117 The object name (aka SHA-1). For a non-ambiguous abbreviation of
118 the object name append :short. For an abbreviation of the object
119 name with desired length append :short=<length>, where the minimum
120 length is MINIMUM_ABBREV. The length may be exceeded to ensure
121 unique object names.
122 deltabase
124 This expands to the object name of the delta base for the given
125 object, if it is stored as a delta. Otherwise it expands to the
126 null object name (all zeroes).
127 upstream
129 The name of a local ref which can be considered “upstream” from the
130 displayed ref. Respects :short, :lstrip and :rstrip in the same way
131 as refname above. Additionally respects :track to show "[ahead N,
132 behind M]" and :trackshort to show the terse version: ">" (ahead),
133 "<" (behind), "<>" (ahead and behind), or "=" (in sync). :track
134 also prints "[gone]" whenever unknown upstream ref is encountered.
135 Append :track,nobracket to show tracking information without
136 brackets (i.e "ahead N, behind M").
137 For any remote-tracking branch %(upstream), %(upstream:remotename)
139 and %(upstream:remoteref) refer to the name of the remote and the
140 name of the tracked remote ref, respectively. In other words, the
141 remote-tracking branch can be updated explicitly and individually
142 by using the refspec %(upstream:remoteref):%(upstream) to fetch
143 from %(upstream:remotename).
144 Has no effect if the ref does not have tracking information
146 associated with it. All the options apart from nobracket are
147 mutually exclusive, but if used together the last option is
148 selected.
149 push
151 The name of a local ref which represents the @{push} location for
152 the displayed ref. Respects :short, :lstrip, :rstrip, :track,
153 :trackshort, :remotename, and :remoteref options as upstream does.
154 Produces an empty string if no @{push} ref is configured.
155 HEAD
157 * if HEAD matches current ref (the checked out branch), ' '
158 otherwise.
159 color
161 Change output color. Followed by :<colorname>, where color names
162 are described under Values in the "CONFIGURATION FILE" section of
163 git-config(1). For example, %(color:bold red).
164 align
166 Left-, middle-, or right-align the content between %(align:...) and
167 %(end). The "align:" is followed by width=<width> and
168 position=<position> in any order separated by a comma, where the
169 <position> is either left, right or middle, default being left and
170 <width> is the total length of the content with alignment. For
171 brevity, the "width=" and/or "position=" prefixes may be omitted,
172 and bare <width> and <position> used instead. For instance,
173 %(align:<width>,<position>). If the contents length is more than
174 the width then no alignment is performed. If used with --quote
175 everything in between %(align:...) and %(end) is quoted, but if
176 nested then only the topmost level performs quoting.
177 if
179 Used as %(if)...%(then)...%(end) or %(if)...%(then)...%(else)...
180 %(end). If there is an atom with value or string literal after the
181 %(if) then everything after the %(then) is printed, else if the
182 %(else) atom is used, then everything after %(else) is printed. We
183 ignore space when evaluating the string before %(then), this is
184 useful when we use the %(HEAD) atom which prints either "*" or " "
185 and we want to apply the if condition only on the HEAD ref. Append
186 ":equals=<string>" or ":notequals=<string>" to compare the value
187 between the %(if:...) and %(then) atoms with the given string.
188 symref
190 The ref which the given symbolic ref refers to. If not a symbolic
191 ref, nothing is printed. Respects the :short, :lstrip and :rstrip
192 options in the same way as refname above.
193 worktreepath
195 The absolute path to the worktree in which the ref is checked out,
196 if it is checked out in any linked worktree. Empty string
197 otherwise.
198 In addition to the above, for commit and tag objects, the header field
200 names (tree, parent, object, type, and tag) can be used to specify the
201 value in the header field.
202 For commit and tag objects, the special creatordate and creator fields
204 will correspond to the appropriate date or name-email-date tuple from
205 the committer or tagger fields depending on the object type. These are
206 intended for working on a mix of annotated and lightweight tags.
207 Fields that have name-email-date tuple as its value (author, committer,
209 and tagger) can be suffixed with name, email, and date to extract the
210 named component.
211 The complete message in a commit and tag object is contents. Its first
213 line is contents:subject, where subject is the concatenation of all
214 lines of the commit message up to the first blank line. The next line
215 is contents:body, where body is all of the lines after the first blank
216 line. The optional GPG signature is contents:signature. The first N
217 lines of the message is obtained using contents:lines=N. Additionally,
218 the trailers as interpreted by git-interpret-trailers(1) are obtained
219 as trailers (or by using the historical alias contents:trailers).
220 Non-trailer lines from the trailer block can be omitted with
221 trailers:only. Whitespace-continuations can be removed from trailers so
222 that each trailer appears on a line by itself with its full content
223 with trailers:unfold. Both can be used together as
224 trailers:unfold,only.
225 For sorting purposes, fields with numeric values sort in numeric order
227 (objectsize, authordate, committerdate, creatordate, taggerdate). All
228 other fields are used to sort in their byte-value order.
229 There is also an option to sort by versions, this can be done by using
231 the fieldname version:refname or its alias v:refname.
232 In any case, a field name that refers to a field inapplicable to the
234 object referred by the ref does not cause an error. It returns an empty
235 string instead.
236 As a special case for the date-type fields, you may specify a format
238 for the date by adding : followed by date format name (see the values
239 the --date option to git-rev-list(1) takes).
240 Some atoms like %(align) and %(if) always require a matching %(end). We
242 call them "opening atoms" and sometimes denote them as %($open).
243 When a scripting language specific quoting is in effect, everything
245 between a top-level opening atom and its matching %(end) is evaluated
246 according to the semantics of the opening atom and only its result from
247 the top-level is quoted.
248
250 An example directly producing formatted text. Show the most recent 3
251 tagged commits:
252 #!/bin/sh
254 git for-each-ref --count=3 --sort='-*authordate' \
256 --format='From: %(*authorname) %(*authoremail)
257 Subject: %(*subject)
258 Date: %(*authordate)
259 Ref: %(*refname)
260 %(*body)
262 ' 'refs/tags'
263 A simple example showing the use of shell eval on the output,
265 demonstrating the use of --shell. List the prefixes of all heads:
266 #!/bin/sh
268 git for-each-ref --shell --format="ref=%(refname)" refs/heads | \
270 while read entry
271 do
272 eval "$entry"
273 echo `dirname $ref`
274 done
275 A bit more elaborate report on tags, demonstrating that the format may
277 be an entire script:
278 #!/bin/sh
280 fmt='
282 r=%(refname)
283 t=%(*objecttype)
284 T=${r#refs/tags/}
285 o=%(*objectname)
287 n=%(*authorname)
288 e=%(*authoremail)
289 s=%(*subject)
290 d=%(*authordate)
291 b=%(*body)
292 kind=Tag
294 if test "z$t" = z
295 then
296 # could be a lightweight tag
297 t=%(objecttype)
298 kind="Lightweight tag"
299 o=%(objectname)
300 n=%(authorname)
301 e=%(authoremail)
302 s=%(subject)
303 d=%(authordate)
304 b=%(body)
305 fi
306 echo "$kind $T points at a $t object $o"
307 if test "z$t" = zcommit
308 then
309 echo "The commit was authored by $n $e
310 at $d, and titled
311 $s
313 Its message reads as:
315 "
316 echo "$b" | sed -e "s/^/ /"
317 echo
318 fi
319 '
320 eval=`git for-each-ref --shell --format="$fmt" \
322 --sort='*objecttype' \
323 --sort=-taggerdate \
324 refs/tags`
325 eval "$eval"
326 An example to show the usage of %(if)...%(then)...%(else)...%(end).
328 This prefixes the current branch with a star.
329 git for-each-ref --format="%(if)%(HEAD)%(then)* %(else) %(end)%(refname:short)" refs/heads/
331 An example to show the usage of %(if)...%(then)...%(end). This prints
333 the authorname, if present.
334 git for-each-ref --format="%(refname)%(if)%(authorname)%(then) Authored by: %(authorname)%(end)"
336
338 Note that the sizes of objects on disk are reported accurately, but
339 care should be taken in drawing conclusions about which refs or objects
340 are responsible for disk usage. The size of a packed non-delta object
341 may be much larger than the size of objects which delta against it, but
342 the choice of which object is the base and which is the delta is
343 arbitrary and is subject to change during a repack.
344 Note also that multiple copies of an object may be present in the
346 object database; in this case, it is undefined which copy’s size or
347 delta base will be reported.
