6 git-for-each-ref - Output information on each ref
11 'git for-each-ref' [--count=<count>] [--shell|--perl|--python|--tcl]
12 [(--sort=<key>)...] [--format=<format>] [<pattern>...]
13 [--points-at <object>] [(--merged | --no-merged) [<object>]]
14 [--contains [<object>]]
19 Iterate over all refs that match `<pattern>` and show them
20 according to the given `<format>`, after sorting them according
21 to the given set of `<key>`. If `<count>` is given, stop after
22 showing that many refs. The interpolated values in `<format>`
23 can optionally be quoted as string literals in the specified
24 host language allowing their direct evaluation in that language.
29 By default the command shows all refs that match
30 `<pattern>`. This option makes it stop after showing
34 A field name to sort on. Prefix `-` to sort in
35 descending order of the value. When unspecified,
36 `refname` is used. You may use the --sort=<key> option
37 multiple times, in which case the last key becomes the primary
41 A string that interpolates `%(fieldname)` from the
42 object pointed at by a ref being shown. If `fieldname`
43 is prefixed with an asterisk (`*`) and the ref points
44 at a tag object, the value for the field in the object
45 tag refers is used. When unspecified, defaults to
46 `%(objectname) SPC %(objecttype) TAB %(refname)`.
47 It also interpolates `%%` to `%`, and `%xx` where `xx`
48 are hex digits interpolates to character with hex code
49 `xx`; for example `%00` interpolates to `\0` (NUL),
50 `%09` to `\t` (TAB) and `%0a` to `\n` (LF).
53 If one or more patterns are given, only refs are shown that
54 match against at least one pattern, either using fnmatch(3) or
55 literally, in the latter case matching completely or from the
56 beginning up to a slash.
62 If given, strings that substitute `%(fieldname)`
63 placeholders are quoted as string literals suitable for
64 the specified host language. This is meant to produce
65 a scriptlet that can directly be `eval`ed.
67 --points-at <object>::
68 Only list refs which points at the given object.
71 Only list refs whose tips are reachable from the
72 specified commit (HEAD if not specified).
74 --no-merged [<object>]::
75 Only list refs whose tips are not reachable from the
76 specified commit (HEAD if not specified).
78 --contains [<object>]::
79 Only list refs which contain the specified commit (HEAD if not
83 Sorting and filtering refs are case insensitive.
88 Various values from structured fields in referenced objects can
89 be used to interpolate into the resulting output, or as sort
92 For all objects, the following names can be used:
95 The name of the ref (the part after $GIT_DIR/).
96 For a non-ambiguous short name of the ref append `:short`.
97 The option core.warnAmbiguousRefs is used to select the strict
98 abbreviation mode. If `strip=<N>` is appended, strips `<N>`
99 slash-separated path components from the front of the refname
100 (e.g., `%(refname:strip=2)` turns `refs/tags/foo` into `foo`.
101 `<N>` must be a positive integer. If a displayed ref has fewer
102 components than `<N>`, the command aborts with an error.
105 The type of the object (`blob`, `tree`, `commit`, `tag`).
108 The size of the object (the same as 'git cat-file -s' reports).
111 The object name (aka SHA-1).
112 For a non-ambiguous abbreviation of the object name append `:short`.
115 The name of a local ref which can be considered ``upstream''
116 from the displayed ref. Respects `:short` in the same way as
117 `refname` above. Additionally respects `:track` to show
118 "[ahead N, behind M]" and `:trackshort` to show the terse
119 version: ">" (ahead), "<" (behind), "<>" (ahead and behind),
120 or "=" (in sync). Has no effect if the ref does not have
121 tracking information associated with it.
124 The name of a local ref which represents the `@{push}` location
125 for the displayed ref. Respects `:short`, `:track`, and
126 `:trackshort` options as `upstream` does. Produces an empty
127 string if no `@{push}` ref is configured.
130 '*' if HEAD matches current ref (the checked out branch), ' '
134 Change output color. Followed by `:<colorname>`, where names
135 are described in `color.branch.*`.
138 Left-, middle-, or right-align the content between
139 %(align:...) and %(end). The "align:" is followed by
140 `width=<width>` and `position=<position>` in any order
141 separated by a comma, where the `<position>` is either left,
142 right or middle, default being left and `<width>` is the total
143 length of the content with alignment. For brevity, the
144 "width=" and/or "position=" prefixes may be omitted, and bare
145 <width> and <position> used instead. For instance,
146 `%(align:<width>,<position>)`. If the contents length is more
147 than the width then no alignment is performed. If used with
148 `--quote` everything in between %(align:...) and %(end) is
149 quoted, but if nested then only the topmost level performs
152 In addition to the above, for commit and tag objects, the header
153 field names (`tree`, `parent`, `object`, `type`, and `tag`) can
154 be used to specify the value in the header field.
156 For commit and tag objects, the special `creatordate` and `creator`
157 fields will correspond to the appropriate date or name-email-date tuple
158 from the `committer` or `tagger` fields depending on the object type.
159 These are intended for working on a mix of annotated and lightweight tags.
161 Fields that have name-email-date tuple as its value (`author`,
162 `committer`, and `tagger`) can be suffixed with `name`, `email`,
163 and `date` to extract the named component.
165 The complete message in a commit and tag object is `contents`.
166 Its first line is `contents:subject`, where subject is the concatenation
167 of all lines of the commit message up to the first blank line. The next
168 line is 'contents:body', where body is all of the lines after the first
169 blank line. The optional GPG signature is `contents:signature`. The
170 first `N` lines of the message is obtained using `contents:lines=N`.
171 Additionally, the trailers as interpreted by linkgit:git-interpret-trailers[1]
172 are obtained as 'contents:trailers'.
174 For sorting purposes, fields with numeric values sort in numeric order
175 (`objectsize`, `authordate`, `committerdate`, `creatordate`, `taggerdate`).
176 All other fields are used to sort in their byte-value order.
178 There is also an option to sort by versions, this can be done by using
179 the fieldname `version:refname` or its alias `v:refname`.
181 In any case, a field name that refers to a field inapplicable to
182 the object referred by the ref does not cause an error. It
183 returns an empty string instead.
185 As a special case for the date-type fields, you may specify a format for
186 the date by adding `:` followed by date format name (see the
187 values the `--date` option to linkgit:git-rev-list[1] takes).

210 A simple example showing the use of shell eval on the output,
211 demonstrating the use of --shell. List the prefixes of all heads:
215 git for-each-ref --shell --format="ref=%(refname)" refs/heads | \
224 A bit more elaborate report on tags, demonstrating that the format
225 may be an entire script:
244 # could be a lightweight tag
246 kind="Lightweight tag"
254 echo "$kind $T points at a $t object $o"
255 if test "z$t" = zcommit
257 echo "The commit was authored by $n $e
262 Its message reads as:
264 echo "$b" | sed -e "s/^/ /"
