NAMEgit-for-each-ref - Output information on each refSYNOPSISgit for-each-ref [--count=<count>] [--shell|--perl|--python|--tcl] [(--sort=<key>)...] [--format=<format>] [<pattern>...] [--points-at=<object>] [--merged[=<object>]] [--no-merged[=<object>]] [--contains[=<object>]] [--no-contains[=<object>]] DESCRIPTIONIterate 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.OPTIONS<pattern>...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.
--count=<count> By default the command shows all refs that match
<pattern>. This option makes it stop after showing that many
refs.
--sort=<key> A field name to sort on. Prefix - to sort in
descending order of the value. When unspecified, refname is used. You
may use the --sort=<key> option multiple times, in which case the last
key becomes the primary key.
--format=<format> A string that interpolates %(fieldname) from a ref
being shown and the object it points at. If fieldname is prefixed with
an asterisk (*) and the ref points at a tag object, use the value for
the field in the object which the tag object refers to (instead of the field
in the tag object). When unspecified, <format> defaults to
%(objectname) SPC %(objecttype) TAB %(refname). It also interpolates
%% to %, and %xx where xx are hex digits
interpolates to character with hex code xx; for example %00
interpolates to \0 (NUL), %09 to \t (TAB) and %0a
to \n (LF).
--color[=<when>] Respect any colors specified in the --format
option. The <when> field must be one of always,
never, or auto (if <when> is absent, behave as if
always was given).
--shell, --perl, --python, --tcl If given, strings that substitute %(fieldname)
placeholders are quoted as string literals suitable for the specified host
language. This is meant to produce a scriptlet that can directly be
`eval`ed.
--points-at=<object> Only list refs which points at the given object.
--merged[=<object>] Only list refs whose tips are reachable from the
specified commit (HEAD if not specified).
--no-merged[=<object>] Only list refs whose tips are not reachable from the
specified commit (HEAD if not specified).
--contains[=<object>] Only list refs which contain the specified commit (HEAD
if not specified).
--no-contains[=<object>] Only list refs which don’t contain the specified
commit (HEAD if not specified).
--ignore-case Sorting and filtering refs are case insensitive.
FIELD NAMESVarious 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: refname 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
lstrip=<N> (rstrip=<N>) is appended, strips
<N> slash-separated path components from the front (back) of the
refname (e.g. %(refname:lstrip=2) turns refs/tags/foo into
foo and %(refname:rstrip=2) turns refs/tags/foo into
refs). If <N> is a negative number, strip as many path
components as necessary from the specified end to leave -<N> path
components (e.g. %(refname:lstrip=-2) turns refs/tags/foo into
tags/foo and %(refname:rstrip=-1) turns refs/tags/foo
into refs). When the ref does not have enough components, the result
becomes an empty string if stripping with positive <N>, or it becomes
the full refname if stripping with negative <N>. Neither is an error.
strip can be used as a synonym to lstrip. objecttype The type of the object (blob, tree,
commit, tag).
objectsize The size of the object (the same as git cat-file
-s reports). Append :disk to get the size, in bytes, that the
object takes up on disk. See the note about on-disk sizes in the
CAVEATS section below.
objectname The object name (aka SHA-1). For a non-ambiguous
abbreviation of the object name append :short. For an abbreviation of
the object name with desired length append :short=<length>, where
the minimum length is MINIMUM_ABBREV. The length may be exceeded to ensure
unique object names.
deltabase This expands to the object name of the delta base for the
given object, if it is stored as a delta. Otherwise it expands to the null
object name (all zeroes).
upstream The name of a local ref which can be considered
“upstream” from the displayed ref. Respects :short,
:lstrip and :rstrip in the same way as refname above.
Additionally respects :track to show "[ahead N, behind M]"
and :trackshort to show the terse version: ">" (ahead),
"<" (behind), "<>" (ahead and behind), or
"=" (in sync). :track also prints "[gone]" whenever
unknown upstream ref is encountered. Append :track,nobracket to show
tracking information without brackets (i.e "ahead N, behind M").
For any remote-tracking branch %(upstream), %(upstream:remotename) and %(upstream:remoteref) refer to the name of the remote and the name of the tracked remote ref, respectively. In other words, the remote-tracking branch can be updated explicitly and individually by using the refspec %(upstream:remoteref):%(upstream) to fetch from %(upstream:remotename). Has no effect if the ref does not have tracking information associated with it. All the options apart from nobracket are mutually exclusive, but if used together the last option is selected. push The name of a local ref which represents the
@{push} location for the displayed ref. Respects :short,
:lstrip, :rstrip, :track, :trackshort,
:remotename, and :remoteref options as upstream does.
Produces an empty string if no @{push} ref is configured.
HEAD * if HEAD matches current ref (the checked out
branch), ' ' otherwise.
color Change output color. Followed by
:<colorname>, where color names are described under Values in the
"CONFIGURATION FILE" section of git-config(1). For example,
%(color:bold red).
align Left-, middle-, or right-align the content between
%(align:...) and %(end). The "align:" is followed by
width=<width> and position=<position> in any order
separated by a comma, where the <position> is either left, right
or middle, default being left and <width> is the total length of
the content with alignment. For brevity, the "width=" and/or
"position=" prefixes may be omitted, and bare <width> and
<position> used instead. For instance,
%(align:<width>,<position>). If the contents length is more
than the width then no alignment is performed. If used with --quote
everything in between %(align:...) and %(end) is quoted, but if nested then
only the topmost level performs quoting.
if Used as %(if)...%(then)...%(end) or
%(if)...%(then)...%(else)...%(end). If there is an atom with value or string
literal after the %(if) then everything after the %(then) is printed, else if
the %(else) atom is used, then everything after %(else) is printed. We ignore
space when evaluating the string before %(then), this is useful when we use
the %(HEAD) atom which prints either "*" or " " and we
want to apply the if condition only on the HEAD ref. Append
":equals=<string>" or ":notequals=<string>" to
compare the value between the %(if:...) and %(then) atoms with the given
string.
symref The ref which the given symbolic ref refers to. If not a
symbolic ref, nothing is printed. Respects the :short, :lstrip
and :rstrip options in the same way as refname above.
worktreepath The absolute path to the worktree in which the ref is
checked out, if it is checked out in any linked worktree. Empty string
otherwise.
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. Fields tree and parent can also be used with modifier :short and :short=<length> just like objectname. 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. For email fields (authoremail, committeremail and taggeremail), :trim can be appended to get the email without angle brackets, and :localpart to get the part before the @ symbol out of the trimmed email. The raw data in an object is raw. raw:size The raw data size of the object.
Note that --format=%(raw) can not be used with --python, --shell, --tcl, because such language may not support arbitrary binary data in their string variable type. The message in a commit or a tag object is contents, from which contents:<part> can be used to extract various parts out of: contents:size The size in bytes of the commit or tag message.
contents:subject The first paragraph of the message, which typically is a
single line, is taken as the "subject" of the commit or the tag
message. Instead of contents:subject, field subject can also be
used to obtain same results. :sanitize can be appended to
subject for subject line suitable for filename.
contents:body The remainder of the commit or the tag message that
follows the "subject".
contents:signature The optional GPG signature of the tag.
contents:lines=N The first N lines of the message.
Additionally, the trailers as interpreted by git-interpret-trailers(1) are obtained as trailers[:options] (or by using the historical alias contents:trailers[:options]). For valid [:option] values see trailers section of git-log(1). 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). Some atoms like %(align) and %(if) always require a matching %(end). We call them "opening atoms" and sometimes denote them as %($open). When a scripting language specific quoting is in effect, everything between a top-level opening atom and its matching %(end) is evaluated according to the semantics of the opening atom and only its result from the top-level is quoted. EXAMPLESAn example directly producing formatted text. Show the most recent 3 tagged commits:#!/bin/sh git for-each-ref --count=3 --sort='-*authordate' \ --format='From: %(*authorname) %(*authoremail) Subject: %(*subject) Date: %(*authordate) Ref: %(*refname) %(*body) ' 'refs/tags' A simple example showing the use of shell eval on the output, demonstrating the use of --shell. List the prefixes of all heads: #!/bin/sh git for-each-ref --shell --format="ref=%(refname)" refs/heads | \ while read entry do eval "$entry" echo `dirname $ref` done A bit more elaborate report on tags, demonstrating that the format may be an entire script: #!/bin/sh fmt=' r=%(refname) t=%(*objecttype) T=${r#refs/tags/} o=%(*objectname) n=%(*authorname) e=%(*authoremail) s=%(*subject) d=%(*authordate) b=%(*body) kind=Tag if test "z$t" = z then # could be a lightweight tag t=%(objecttype) kind="Lightweight tag" o=%(objectname) n=%(authorname) e=%(authoremail) s=%(subject) d=%(authordate) b=%(body) fi echo "$kind $T points at a $t object $o" if test "z$t" = zcommit then echo "The commit was authored by $n $e at $d, and titled $s Its message reads as: " echo "$b" | sed -e "s/^/ /" echo fi ' eval=`git for-each-ref --shell --format="$fmt" \ --sort='*objecttype' \ --sort=-taggerdate \ refs/tags` eval "$eval" An example to show the usage of %(if)...%(then)...%(else)...%(end). This prefixes the current branch with a star. git for-each-ref --format="%(if)%(HEAD)%(then)* %(else) %(end)%(refname:short)" refs/heads/ An example to show the usage of %(if)...%(then)...%(end). This prints the authorname, if present. git for-each-ref --format="%(refname)%(if)%(authorname)%(then) Authored by: %(authorname)%(end)" CAVEATSNote that the sizes of objects on disk are reported accurately, but care should be taken in drawing conclusions about which refs or objects are responsible for disk usage. The size of a packed non-delta object may be much larger than the size of objects which delta against it, but the choice of which object is the base and which is the delta is arbitrary and is subject to change during a repack.Note also that multiple copies of an object may be present in the object database; in this case, it is undefined which copy’s size or delta base will be reported. NOTESWhen combining multiple --contains and --no-contains filters, only references that contain at least one of the --contains commits and contain none of the --no-contains commits are shown.When combining multiple --merged and --no-merged filters, only references that are reachable from at least one of the --merged commits and from none of the --no-merged commits are shown.
