git-rev-parse(1)
================

NAME
----
git-rev-parse - Pick out and massage parameters.


SYNOPSIS
--------
'git-rev-parse' [ --option ] <args>...

DESCRIPTION
-----------

Many git Porcelainish commands take mixture of flags
(i.e. parameters that begin with a dash '-') and parameters
meant for underlying `git-rev-list` command they use internally
and flags and parameters for other commands they use as the
downstream of `git-rev-list`.  This command is used to
distinguish between them.


OPTIONS
-------
--revs-only::
	Do not output flags and parameters not meant for
	`git-rev-list` command.

--no-revs::
	Do not output flags and parameters meant for
	`git-rev-list` command.

--flags::
	Do not output non-flag parameters.

--no-flags::
	Do not output flag parameters.

--default <arg>::
	If there is no parameter given by the user, use `<arg>`
	instead.

--verify::
	The parameter given must be usable as a single, valid
	object name.  Otherwise barf and abort.

--sq::
	Usually the output is made one line per flag and
	parameter.  This option makes output a single line,
	properly quoted for consumption by shell.  Useful when
	you expect your parameter to contain whitespaces and
	newlines (e.g. when using pickaxe `-S` with
	`git-diff-\*`).

--not::
	When showing object names, prefix them with '^' and
	strip '^' prefix from the object names that already have
	one.

--symbolic::
	Usually the object names are output in SHA1 form (with
	possible '^' prefix); this option makes them output in a
	form as close to the original input as possible.


--all::
	Show all refs found in `$GIT_DIR/refs`.

--show-prefix::
	When the command is invoked from a directory show the
	path of the current directory relative to the top-level
	directory.

<args>...::
	Flags and parameters to be parsed.
