+git-for-each-ref(1)
+===================
+
+NAME
+----
+git-for-each-ref - Output information on each ref
+
+SYNOPSIS
+--------
+'git-for-each-ref' [--count=<count>]* [--shell|--perl|--python] [--sort=<key>]* [--format=<format>] [<pattern>]
+
+DESCRIPTION
+-----------
+
+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>`s.  If `<max>` is given, stop after
+showing that many refs.  The interporated values in `<format>`
+can optionally be quoted as string literals in the specified
+host language allowing their direct evaluation in that language.
+
+OPTIONS
+-------
+<count>::
+       By default the command shows all refs that match
+       `<pattern>`.  This option makes it stop after showing
+       that many refs.
+
+<key>::
+       A field name to sort on.  Prefix `-` to sort in
+       descending order of the value.  When unspecified,
+       `refname` is used.  More than one sort keys can be
+       given.
+
+<format>::
+       A string that interpolates `%(fieldname)` from the
+       object pointed at by a ref being shown.  If `fieldname`
+       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
+       `%(refname)`.
+
+<pattern>::
+       If given, the name of the ref is matched against this
+       using fnmatch(3).  Refs that do not match the pattern
+       are not shown.
+
+--shell, --perl, --python::
+       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.
+
+
+FIELD NAMES
+-----------
+
+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:
+
+refname::
+       The name of the ref (the part after $GIT_DIR/refs/).
+
+objecttype::
+       The type of the object (`blob`, `tree`, `commit`, `tag`).
+
+objectsize::
+       The size of the object (the same as `git-cat-file -s` reports).
+
+objectname::
+       The object name (aka SHA-1).
+
+In addition to the above, for commit and tag objects, the header
+field names (`tree`, `parent`, `object`, `type`, and `tag`) can
+be used to specify the value in the header field.
+
+Fields that have name-email-date tuple as its value (`author`,
+`committer`, and `tagger`) can be suffixed with `name`, `email`,
+and `date` to extract the named component.
+
+The first line of the message in a commit and tag object is
+`subject`, the remaining lines are `body`.  The whole message
+is `contents`.
+
+For sorting purposes, fields with numeric values sort in numeric
+order (`objectsize`, `authordate`, `committerdate`, `taggerdate`).
+All other fields are used to sort in their byte-value order.
+
+In any case, a field name that refers to a field inapplicable to
+the object referred by the ref does not cause an error.  It
+returns an empty string instead.
+
+
+EXAMPLES
+--------
+
+An example directly producing formatted text.  Show the most recent
+3 tagged commits::
+
+------------
+#!/bin/sh
+
+git-for-each-ref --count=3 --sort='-*authordate' \
+--format='From: %(*authorname) %(*authoremail)
+Subject: %(*subject)
+Date: %(*authordate)
+Ref: %(*refname)
+
+%(*body)
+' 'refs/tags'
+------------
+
+
+A simple example showing the use of shell eval on the output,
+demonstrating the use of --shell.  List the prefixes of all heads::
+------------
+#!/bin/sh
+
+git-for-each-ref --shell --format="ref=%(refname)" refs/heads | \
+while read entry
+do
+       eval "$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
