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 tags which contain the specified commit (HEAD if not
85 Various values from structured fields in referenced objects can
86 be used to interpolate into the resulting output, or as sort
89 For all objects, the following names can be used:
92 The name of the ref (the part after $GIT_DIR/).
93 For a non-ambiguous short name of the ref append `:short`.
94 The option core.warnAmbiguousRefs is used to select the strict
95 abbreviation mode. If `strip=<N>` is appended, strips `<N>`
96 slash-separated path components from the front of the refname
97 (e.g., `%(refname:strip=2)` turns `refs/tags/foo` into `foo`.
98 `<N>` must be a positive integer. If a displayed ref has fewer
99 components than `<N>`, the command aborts with an error.
102 The type of the object (`blob`, `tree`, `commit`, `tag`).
105 The size of the object (the same as 'git cat-file -s' reports).
108 The object name (aka SHA-1).
109 For a non-ambiguous abbreviation of the object name append `:short`.
112 The name of a local ref which can be considered ``upstream''
113 from the displayed ref. Respects `:short` in the same way as
114 `refname` above. Additionally respects `:track` to show
115 "[ahead N, behind M]" and `:trackshort` to show the terse
116 version: ">" (ahead), "<" (behind), "<>" (ahead and behind),
117 or "=" (in sync). Has no effect if the ref does not have
118 tracking information associated with it.
121 The name of a local ref which represents the `@{push}` location
122 for the displayed ref. Respects `:short`, `:track`, and
123 `:trackshort` options as `upstream` does. Produces an empty
124 string if no `@{push}` ref is configured.
127 '*' if HEAD matches current ref (the checked out branch), ' '
131 Change output color. Followed by `:<colorname>`, where names
132 are described in `color.branch.*`.
135 Left-, middle-, or right-align the content between
136 %(align:...) and %(end). The "align:" is followed by
137 `width=<width>` and `position=<position>` in any order
138 separated by a comma, where the `<position>` is either left,
139 right or middle, default being left and `<width>` is the total
140 length of the content with alignment. For brevity, the
141 "width=" and/or "position=" prefixes may be omitted, and bare
142 <width> and <position> used instead. For instance,
143 `%(align:<width>,<position>)`. If the contents length is more
144 than the width then no alignment is performed. If used with
145 '--quote' everything in between %(align:...) and %(end) is
146 quoted, but if nested then only the topmost level performs
149 In addition to the above, for commit and tag objects, the header
150 field names (`tree`, `parent`, `object`, `type`, and `tag`) can
151 be used to specify the value in the header field.
153 Fields that have name-email-date tuple as its value (`author`,
154 `committer`, and `tagger`) can be suffixed with `name`, `email`,
155 and `date` to extract the named component.
157 The complete message in a commit and tag object is `contents`.
158 Its first line is `contents:subject`, where subject is the concatenation
159 of all lines of the commit message up to the first blank line. The next
160 line is 'contents:body', where body is all of the lines after the first
161 blank line. The optional GPG signature is `contents:signature`. The
162 first `N` lines of the message is obtained using `contents:lines=N`.
164 For sorting purposes, fields with numeric values sort in numeric
165 order (`objectsize`, `authordate`, `committerdate`, `taggerdate`).
166 All other fields are used to sort in their byte-value order.
168 There is also an option to sort by versions, this can be done by using
169 the fieldname `version:refname` or its alias `v:refname`.
171 In any case, a field name that refers to a field inapplicable to
172 the object referred by the ref does not cause an error. It
173 returns an empty string instead.
175 As a special case for the date-type fields, you may specify a format for
176 the date by adding `:` followed by date format name (see the
177 values the `--date` option to linkgit::git-rev-list[1] takes).

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