git-for-each-ref - Output information on each ref
git for-each-ref [--count=<count>] [--shell|--perl|--python|--tcl]
[(--sort=<key>)...] [--format=<format>] [<pattern>...]
[--points-at <object>] [(--merged | --no-merged) [<object>]]
Iterate over all refs that match <pattern> and show them according to the given <format>, after sorting them according to the given set of <key>. If <count> is given, stop after showing that many refs. The interpolated values in <format> can optionally be quoted as string literals in the specified host language allowing their direct evaluation in that language.
By default the command shows all refs that match
<pattern>. This option makes it stop after showing that many refs.
A field name to sort on. Prefix
to sort in descending order of the value. When unspecified,
is used. You may use the --sort=<key> option multiple times, in which case the last key becomes the primary key.
A string that interpolates
from the object pointed at by a ref being shown. If
is prefixed with an asterisk (*) and the ref points at a tag object, the value for the field in the object tag refers is used. When unspecified, defaults to
%(objectname) SPC %(objecttype) TAB %(refname). It also interpolates
are hex digits interpolates to character with hex code
xx; for example
If one or more patterns are given, only refs are shown that match against at least one pattern, either using fnmatch(3) or literally, in the latter case matching completely or from the beginning up to a slash.
--shell, --perl, --python, --tcl
If given, strings that substitute
placeholders are quoted as string literals suitable for the specified host language. This is meant to produce a scriptlet that can directly be evaled.
Only list refs which points at the given object.
Only list refs whose tips are reachable from the specified commit (HEAD if not specified).
Only list refs whose tips are not reachable from the specified commit (HEAD if not specified).
Only list tags which contain the specified commit (HEAD if not specified).
Various values from structured fields in referenced objects can be used to interpolate into the resulting output, or as sort keys.
For all objects, the following names can be used:
The name of the ref (the part after $GIT_DIR/). For a non-ambiguous short name of the ref append
:short. The option core.warnAmbiguousRefs is used to select the strict abbreviation mode. If
is appended, strips
slash-separated path components from the front of the refname (e.g.,
must be a positive integer. If a displayed ref has fewer components than
<N>, the command aborts with an error.
The type of the object (blob,
The size of the object (the same as
git cat-file -s
The object name (aka SHA-1). For a non-ambiguous abbreviation of the object name append
The name of a local ref which can be considered upstream from the displayed ref. Respects
in the same way as
above. Additionally respects
to show "[ahead N, behind M]" and
to show the terse version: ">" (ahead), "<" (behind), "<>" (ahead and behind), or "=" (in sync). Has no effect if the ref does not have tracking information associated with it.
The name of a local ref which represents the
location for the displayed ref. Respects
does. Produces an empty string if no
ref is configured.
if HEAD matches current ref (the checked out branch), otherwise.
Change output color. Followed by
:<colorname>, where names are described in
Left-, middle-, or right-align the content between %(align:...) and %(end). The "align:" is followed by
in any order separated by a comma, where the
is either left, right or middle, default being left and
is the total length of the content with alignment. If the contents length is more than the width then no alignment is performed. If used with
everything in between %(align:...) and %(end) is quoted, but if nested then only the topmost level performs quoting.
In addition to the above, for commit and tag objects, the header field names (tree, parent, object, type, and tag) can be used to specify the value in the header field.
For commit and tag objects, the special creatordate and creator fields will correspond to the appropriate date or name-email-date tuple from the committer or tagger fields depending on the object type. These are intended for working on a mix of annotated and lightweight tags.
Fields that have name-email-date tuple as its value (author, committer, and tagger) can be suffixed with name, email, and date to extract the named component.
The complete message in a commit and tag object is contents. Its first line is contents:subject, where subject is the concatenation of all lines of the commit message up to the first blank line. The next line is contents:body, where body is all of the lines after the first blank line. The optional GPG signature is contents:signature. The first N lines of the message is obtained using contents:lines=N.
For sorting purposes, fields with numeric values sort in numeric order (objectsize, authordate, committerdate, creatordate, taggerdate). All other fields are used to sort in their byte-value order.
There is also an option to sort by versions, this can be done by using the fieldname version:refname or its alias v:refname.
In any case, a field name that refers to a field inapplicable to the object referred by the ref does not cause an error. It returns an empty string instead.
As a special case for the date-type fields, you may specify a format for the date by adding : followed by date format name (see the values the --date option to :git-rev-list(1) takes).
An example directly producing formatted text. Show the most recent 3 tagged commits:
git for-each-ref --count=3 --sort=-*authordate \
--format=From: %(*authorname) %(*authoremail)
A simple example showing the use of shell eval on the output, demonstrating the use of --shell. List the prefixes of all heads:
git for-each-ref --shell --format="ref=%(refname)" refs/heads | \
while read entry
echo dirname $ref
A bit more elaborate report on tags, demonstrating that the format may be an entire script:
if test "z$t" = z
# could be a lightweight tag
echo "$kind $T points at a $t object $o"
if test "z$t" = zcommit
echo "The commit was authored by $n $e
at $d, and titled
Its message reads as:
echo "$b" | sed -e "s/^/ /"
eval=git for-each-ref --shell --format="$fmt" \
