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>...]
17 Iterate over all refs that match `<pattern>` and show them
18 according to the given `<format>`, after sorting them according
19 to the given set of `<key>`. If `<count>` is given, stop after
20 showing that many refs. The interpolated values in `<format>`
21 can optionally be quoted as string literals in the specified
22 host language allowing their direct evaluation in that language.
27 By default the command shows all refs that match
28 `<pattern>`. This option makes it stop after showing
32 A field name to sort on. Prefix `-` to sort in
33 descending order of the value. When unspecified,
34 `refname` is used. You may use the --sort=<key> option
35 multiple times, in which case the last key becomes the primary
39 A string that interpolates `%(fieldname)` from the
40 object pointed at by a ref being shown. If `fieldname`
41 is prefixed with an asterisk (`*`) and the ref points
42 at a tag object, the value for the field in the object
43 tag refers is used. When unspecified, defaults to
44 `%(objectname) SPC %(objecttype) TAB %(refname)`.
45 It also interpolates `%%` to `%`, and `%xx` where `xx`
46 are hex digits interpolates to character with hex code
47 `xx`; for example `%00` interpolates to `\0` (NUL),
48 `%09` to `\t` (TAB) and `%0a` to `\n` (LF).
51 If one or more patterns are given, only refs are shown that
52 match against at least one pattern, either using fnmatch(3) or
53 literally, in the latter case matching completely or from the
54 beginning up to a slash.
60 If given, strings that substitute `%(fieldname)`
61 placeholders are quoted as string literals suitable for
62 the specified host language. This is meant to produce
63 a scriptlet that can directly be `eval`ed.
69 Various values from structured fields in referenced objects can
70 be used to interpolate into the resulting output, or as sort
73 For all objects, the following names can be used:
76 The name of the ref (the part after $GIT_DIR/).
77 For a non-ambiguous short name of the ref append `:short`.
78 The option core.warnAmbiguousRefs is used to select the strict
82 The type of the object (`blob`, `tree`, `commit`, `tag`).
85 The size of the object (the same as 'git cat-file -s' reports).
88 The object name (aka SHA-1).
89 For a non-ambiguous abbreviation of the object name append `:short`.
92 The name of a local ref which can be considered ``upstream''
93 from the displayed ref. Respects `:short` in the same way as
94 `refname` above. Additionally respects `:track` to show
95 "[ahead N, behind M]" and `:trackshort` to show the terse
96 version: ">" (ahead), "<" (behind), "<>" (ahead and behind),
97 or "=" (in sync). Has no effect if the ref does not have
98 tracking information associated with it.
101 '*' if HEAD matches current ref (the checked out branch), ' '
105 Change output color. Followed by `:<colorname>`, where names
106 are described in `color.branch.*`.
108 In addition to the above, for commit and tag objects, the header
109 field names (`tree`, `parent`, `object`, `type`, and `tag`) can
110 be used to specify the value in the header field.
112 Fields that have name-email-date tuple as its value (`author`,
113 `committer`, and `tagger`) can be suffixed with `name`, `email`,
114 and `date` to extract the named component.
116 The complete message in a commit and tag object is `contents`.
117 Its first line is `contents:subject`, where subject is the concatenation
118 of all lines of the commit message up to the first blank line. The next
119 line is 'contents:body', where body is all of the lines after the first
120 blank line. Finally, the optional GPG signature is `contents:signature`.
122 For sorting purposes, fields with numeric values sort in numeric
123 order (`objectsize`, `authordate`, `committerdate`, `taggerdate`).
124 All other fields are used to sort in their byte-value order.
126 In any case, a field name that refers to a field inapplicable to
127 the object referred by the ref does not cause an error. It
128 returns an empty string instead.
130 As a special case for the date-type fields, you may specify a format for
131 the date by adding one of `:default`, `:relative`, `:short`, `:local`,
132 `:iso8601`, `:rfc2822` or `:raw` to the end of the fieldname; e.g.
133 `%(taggerdate:relative)`.
139 An example directly producing formatted text. Show the most recent
145 git for-each-ref --count=3 --sort='-*authordate' \
146 --format='From: %(*authorname) %(*authoremail)
156 A simple example showing the use of shell eval on the output,
157 demonstrating the use of --shell. List the prefixes of all heads:
161 git for-each-ref --shell --format="ref=%(refname)" refs/heads | \
170 A bit more elaborate report on tags, demonstrating that the format
171 may be an entire script:
190 # could be a lightweight tag
192 kind="Lightweight tag"
200 echo "$kind $T points at a $t object $o"
201 if test "z$t" = zcommit
203 echo "The commit was authored by $n $e
208 Its message reads as:
210 echo "$b" | sed -e "s/^/ /"
215 eval=`git for-each-ref --shell --format="$fmt" \
216 --sort='*objecttype' \
