GIT-REV-PARSE(1)                 Git Manual                 GIT-REV-PARSE(1)

NAME         top

       git-rev-parse - Pick out and massage parameters

SYNOPSIS         top

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

DESCRIPTION         top

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

OPTIONS         top

   Operation Modes
       Each of these options must appear first on the command line.

       --parseopt
           Use git rev-parse in option parsing mode (see PARSEOPT section
           below).

       --sq-quote
           Use git rev-parse in shell quoting mode (see SQ-QUOTE section
           below). In contrast to the --sq option below, this mode does only
           quoting. Nothing else is done to command input.

   Options for --parseopt
       --keep-dashdash
           Only meaningful in --parseopt mode. Tells the option parser to
           echo out the first -- met instead of skipping it.

       --stop-at-non-option
           Only meaningful in --parseopt mode. Lets the option parser stop
           at the first non-option argument. This can be used to parse
           sub-commands that take options themselves.

       --stuck-long
           Only meaningful in --parseopt mode. Output the options in their
           long form if available, and with their arguments stuck.

   Options for Filtering
       --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.

   Options for Output
       --default <arg>
           If there is no parameter given by the user, use <arg> instead.

       --prefix <arg>
           Behave as if git rev-parse was invoked from the <arg>
           subdirectory of the working tree. Any relative filenames are
           resolved as if they are prefixed by <arg> and will be printed in
           that form.

           This can be used to convert arguments to a command run in a
           subdirectory so that they can still be used after moving to the
           top-level of the repository. For example:

               prefix=$(git rev-parse --show-prefix)
               cd "$(git rev-parse --show-toplevel)"
               # rev-parse provides the -- needed for 'set'
               eval "set $(git rev-parse --sq --prefix "$prefix" -- "$@")"

       --verify
           Verify that exactly one parameter is provided, and that it can be
           turned into a raw 20-byte SHA-1 that can be used to access the
           object database. If so, emit it to the standard output;
           otherwise, error out.

           If you want to make sure that the output actually names an object
           in your object database and/or can be used as a specific type of
           object you require, you can add the ^{type} peeling operator to
           the parameter. For example, git rev-parse "$VAR^{commit}" will
           make sure $VAR names an existing object that is a commit-ish
           (i.e. a commit, or an annotated tag that points at a commit). To
           make sure that $VAR names an existing object of any type, git
           rev-parse "$VAR^{object}" can be used.

       -q, --quiet
           Only meaningful in --verify mode. Do not output an error message
           if the first argument is not a valid object name; instead exit
           with non-zero status silently. SHA-1s for valid object names are
           printed to stdout on success.

       --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-*). In contrast to the --sq-quote option, the command
           input is still interpreted as usual.

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

       --abbrev-ref[=(strict|loose)]
           A non-ambiguous short name of the objects name. The option
           core.warnAmbiguousRefs is used to select the strict abbreviation
           mode.

       --short, --short=number
           Instead of outputting the full SHA-1 values of object names try
           to abbreviate them to a shorter unique name. When no length is
           specified 7 is used. The minimum length is 4.

       --symbolic
           Usually the object names are output in SHA-1 form (with possible
           ^ prefix); this option makes them output in a form as close to
           the original input as possible.

       --symbolic-full-name
           This is similar to --symbolic, but it omits input that are not
           refs (i.e. branch or tag names; or more explicitly disambiguating
           "heads/master" form, when you want to name the "master" branch
           when there is an unfortunately named tag "master"), and show them
           as full refnames (e.g. "refs/heads/master").

   Options for Objects
       --all
           Show all refs found in refs/.

       --branches[=pattern], --tags[=pattern], --remotes[=pattern]
           Show all branches, tags, or remote-tracking branches,
           respectively (i.e., refs found in refs/heads, refs/tags, or
           refs/remotes, respectively).

           If a pattern is given, only refs matching the given shell glob
           are shown. If the pattern does not contain a globbing character
           (?, *, or [), it is turned into a prefix match by appending /*.

       --glob=pattern
           Show all refs matching the shell glob pattern pattern. If the
           pattern does not start with refs/, this is automatically
           prepended. If the pattern does not contain a globbing character
           (?, *, or [), it is turned into a prefix match by appending /*.

       --exclude=<glob-pattern>
           Do not include refs matching <glob-pattern> that the next --all,
           --branches, --tags, --remotes, or --glob would otherwise
           consider. Repetitions of this option accumulate exclusion
           patterns up to the next --all, --branches, --tags, --remotes, or
           --glob option (other options or arguments do not clear
           accumulated patterns).

           The patterns given should not begin with refs/heads, refs/tags,
           or refs/remotes when applied to --branches, --tags, or --remotes,
           respectively, and they must begin with refs/ when applied to
           --glob or --all. If a trailing /* is intended, it must be given
           explicitly.

       --disambiguate=<prefix>
           Show every object whose name begins with the given prefix. The
           <prefix> must be at least 4 hexadecimal digits long to avoid
           listing each and every object in the repository by mistake.

   Options for Files
       --local-env-vars
           List the GIT_* environment variables that are local to the
           repository (e.g. GIT_DIR or GIT_WORK_TREE, but not GIT_EDITOR).
           Only the names of the variables are listed, not their value, even
           if they are set.

       --git-dir
           Show $GIT_DIR if defined. Otherwise show the path to the .git
           directory. The path shown, when relative, is relative to the
           current working directory.

           If $GIT_DIR is not defined and the current directory is not
           detected to lie in a Git repository or work tree print a message
           to stderr and exit with nonzero status.

       --absolute-git-dir
           Like --git-dir, but its output is always the canonicalized
           absolute path.

       --git-common-dir
           Show $GIT_COMMON_DIR if defined, else $GIT_DIR.

       --is-inside-git-dir
           When the current working directory is below the repository
           directory print "true", otherwise "false".

       --is-inside-work-tree
           When the current working directory is inside the work tree of the
           repository print "true", otherwise "false".

       --is-bare-repository
           When the repository is bare print "true", otherwise "false".

       --resolve-git-dir <path>
           Check if <path> is a valid repository or a gitfile that points at
           a valid repository, and print the location of the repository. If
           <path> is a gitfile then the resolved path to the real repository
           is printed.

       --git-path <path>
           Resolve "$GIT_DIR/<path>" and takes other path relocation
           variables such as $GIT_OBJECT_DIRECTORY, $GIT_INDEX_FILE... into
           account. For example, if $GIT_OBJECT_DIRECTORY is set to /foo/bar
           then "git rev-parse --git-path objects/abc" returns /foo/bar/abc.

       --show-cdup
           When the command is invoked from a subdirectory, show the path of
           the top-level directory relative to the current directory
           (typically a sequence of "../", or an empty string).

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

       --show-toplevel
           Show the absolute path of the top-level directory.

       --shared-index-path
           Show the path to the shared index file in split index mode, or
           empty if not in split-index mode.

   Other Options
       --since=datestring, --after=datestring
           Parse the date string, and output the corresponding --max-age=
           parameter for git rev-list.

       --until=datestring, --before=datestring
           Parse the date string, and output the corresponding --min-age=
           parameter for git rev-list.

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

SPECIFYING REVISIONS         top

       A revision parameter <rev> typically, but not necessarily, names a
       commit object. It uses what is called an extended SHA-1 syntax. Here
       are various ways to spell object names. The ones listed near the end
       of this list name trees and blobs contained in a commit.

       <sha1>, e.g. dae86e1950b1277e545cee180551750029cfe735, dae86e
           The full SHA-1 object name (40-byte hexadecimal string), or a
           leading substring that is unique within the repository. E.g.
           dae86e1950b1277e545cee180551750029cfe735 and dae86e both name the
           same commit object if there is no other object in your repository
           whose object name starts with dae86e.

       <describeOutput>, e.g. v1.7.4.2-679-g3bee7fb
           Output from git describe; i.e. a closest tag, optionally followed
           by a dash and a number of commits, followed by a dash, a g, and
           an abbreviated object name.

       <refname>, e.g. master, heads/master, refs/heads/master
           A symbolic ref name. E.g.  master typically means the commit
           object referenced by refs/heads/master. If you happen to have
           both heads/master and tags/master, you can explicitly say
           heads/master to tell Git which one you mean. When ambiguous, a
           <refname> is disambiguated by taking the first match in the
           following rules:

            1. If $GIT_DIR/<refname> exists, that is what you mean (this is
               usually useful only for HEAD, FETCH_HEAD, ORIG_HEAD,
               MERGE_HEAD and CHERRY_PICK_HEAD);

            2. otherwise, refs/<refname> if it exists;

            3. otherwise, refs/tags/<refname> if it exists;

            4. otherwise, refs/heads/<refname> if it exists;

            5. otherwise, refs/remotes/<refname> if it exists;

            6. otherwise, refs/remotes/<refname>/HEAD if it exists.

               HEAD names the commit on which you based the changes in the
               working tree.  FETCH_HEAD records the branch which you
               fetched from a remote repository with your last git fetch
               invocation.  ORIG_HEAD is created by commands that move your
               HEAD in a drastic way, to record the position of the HEAD
               before their operation, so that you can easily change the tip
               of the branch back to the state before you ran them.
               MERGE_HEAD records the commit(s) which you are merging into
               your branch when you run git merge.  CHERRY_PICK_HEAD records
               the commit which you are cherry-picking when you run git
               cherry-pick.

               Note that any of the refs/* cases above may come either from
               the $GIT_DIR/refs directory or from the $GIT_DIR/packed-refs
               file. While the ref name encoding is unspecified, UTF-8 is
               preferred as some output processing may assume ref names in
               UTF-8.

       @
           @ alone is a shortcut for HEAD.

       <refname>@{<date>}, e.g. master@{yesterday}, HEAD@{5 minutes ago}
           A ref followed by the suffix @ with a date specification enclosed
           in a brace pair (e.g.  {yesterday}, {1 month 2 weeks 3 days 1
           hour 1 second ago} or {1979-02-26 18:30:00}) specifies the value
           of the ref at a prior point in time. This suffix may only be used
           immediately following a ref name and the ref must have an
           existing log ($GIT_DIR/logs/<ref>). Note that this looks up the
           state of your local ref at a given time; e.g., what was in your
           local master branch last week. If you want to look at commits
           made during certain times, see --since and --until.

       <refname>@{<n>}, e.g. master@{1}
           A ref followed by the suffix @ with an ordinal specification
           enclosed in a brace pair (e.g.  {1}, {15}) specifies the n-th
           prior value of that ref. For example master@{1} is the immediate
           prior value of master while master@{5} is the 5th prior value of
           master. This suffix may only be used immediately following a ref
           name and the ref must have an existing log
           ($GIT_DIR/logs/<refname>).

       @{<n>}, e.g. @{1}
           You can use the @ construct with an empty ref part to get at a
           reflog entry of the current branch. For example, if you are on
           branch blabla then @{1} means the same as blabla@{1}.

       @{-<n>}, e.g. @{-1}
           The construct @{-<n>} means the <n>th branch/commit checked out
           before the current one.

       <branchname>@{upstream}, e.g. master@{upstream}, @{u}
           The suffix @{upstream} to a branchname (short form
           <branchname>@{u}) refers to the branch that the branch specified
           by branchname is set to build on top of (configured with
           branch.<name>.remote and branch.<name>.merge). A missing
           branchname defaults to the current one.

       <branchname>@{push}, e.g. master@{push}, @{push}
           The suffix @{push} reports the branch "where we would push to" if
           git push were run while branchname was checked out (or the
           current HEAD if no branchname is specified). Since our push
           destination is in a remote repository, of course, we report the
           local tracking branch that corresponds to that branch (i.e.,
           something in refs/remotes/).

           Here’s an example to make it more clear:

               $ git config push.default current
               $ git config remote.pushdefault myfork
               $ git checkout -b mybranch origin/master

               $ git rev-parse --symbolic-full-name @{upstream}
               refs/remotes/origin/master

               $ git rev-parse --symbolic-full-name @{push}
               refs/remotes/myfork/mybranch

           Note in the example that we set up a triangular workflow, where
           we pull from one location and push to another. In a
           non-triangular workflow, @{push} is the same as @{upstream}, and
           there is no need for it.

       <rev>^, e.g. HEAD^, v1.5.1^0
           A suffix ^ to a revision parameter means the first parent of that
           commit object.  ^<n> means the <n>th parent (i.e.  <rev>^ is
           equivalent to <rev>^1). As a special rule, <rev>^0 means the
           commit itself and is used when <rev> is the object name of a tag
           object that refers to a commit object.

       <rev>~<n>, e.g. master~3
           A suffix ~<n> to a revision parameter means the commit object
           that is the <n>th generation ancestor of the named commit object,
           following only the first parents. I.e.  <rev>~3 is equivalent to
           <rev>^^^ which is equivalent to <rev>^1^1^1. See below for an
           illustration of the usage of this form.

       <rev>^{<type>}, e.g. v0.99.8^{commit}
           A suffix ^ followed by an object type name enclosed in brace pair
           means dereference the object at <rev> recursively until an object
           of type <type> is found or the object cannot be dereferenced
           anymore (in which case, barf). For example, if <rev> is a
           commit-ish, <rev>^{commit} describes the corresponding commit
           object. Similarly, if <rev> is a tree-ish, <rev>^{tree} describes
           the corresponding tree object.  <rev>^0 is a short-hand for
           <rev>^{commit}.

           rev^{object} can be used to make sure rev names an object that
           exists, without requiring rev to be a tag, and without
           dereferencing rev; because a tag is already an object, it does
           not have to be dereferenced even once to get to an object.

           rev^{tag} can be used to ensure that rev identifies an existing
           tag object.

       <rev>^{}, e.g. v0.99.8^{}
           A suffix ^ followed by an empty brace pair means the object could
           be a tag, and dereference the tag recursively until a non-tag
           object is found.

       <rev>^{/<text>}, e.g. HEAD^{/fix nasty bug}
           A suffix ^ to a revision parameter, followed by a brace pair that
           contains a text led by a slash, is the same as the :/fix nasty
           bug syntax below except that it returns the youngest matching
           commit which is reachable from the <rev> before ^.

       :/<text>, e.g. :/fix nasty bug
           A colon, followed by a slash, followed by a text, names a commit
           whose commit message matches the specified regular expression.
           This name returns the youngest matching commit which is reachable
           from any ref. The regular expression can match any part of the
           commit message. To match messages starting with a string, one can
           use e.g.  :/^foo. The special sequence :/!  is reserved for
           modifiers to what is matched.  :/!-foo performs a negative match,
           while :/!!foo matches a literal !  character, followed by foo.
           Any other sequence beginning with :/!  is reserved for now.

       <rev>:<path>, e.g. HEAD:README, :README, master:./README
           A suffix : followed by a path names the blob or tree at the given
           path in the tree-ish object named by the part before the colon.
           :path (with an empty part before the colon) is a special case of
           the syntax described next: content recorded in the index at the
           given path. A path starting with ./ or ../ is relative to the
           current working directory. The given path will be converted to be
           relative to the working tree’s root directory. This is most
           useful to address a blob or tree from a commit or tree that has
           the same tree structure as the working tree.

       :<n>:<path>, e.g. :0:README, :README
           A colon, optionally followed by a stage number (0 to 3) and a
           colon, followed by a path, names a blob object in the index at
           the given path. A missing stage number (and the colon that
           follows it) names a stage 0 entry. During a merge, stage 1 is the
           common ancestor, stage 2 is the target branch’s version
           (typically the current branch), and stage 3 is the version from
           the branch which is being merged.

       Here is an illustration, by Jon Loeliger. Both commit nodes B and C
       are parents of commit node A. Parent commits are ordered
       left-to-right.

           G   H   I   J
            \ /     \ /
             D   E   F
              \  |  / \
               \ | /   |
                \|/    |
                 B     C
                  \   /
                   \ /
                    A

           A =      = A^0
           B = A^   = A^1     = A~1
           C = A^2  = A^2
           D = A^^  = A^1^1   = A~2
           E = B^2  = A^^2
           F = B^3  = A^^3
           G = A^^^ = A^1^1^1 = A~3
           H = D^2  = B^^2    = A^^^2  = A~2^2
           I = F^   = B^3^    = A^^3^

SPECIFYING RANGES         top

       History traversing commands such as git log operate on a set of
       commits, not just a single commit.

       For these commands, specifying a single revision, using the notation
       described in the previous section, means the set of commits reachable
       from the given commit.

       A commit’s reachable set is the commit itself and the commits in its
       ancestry chain.

   Commit Exclusions
       ^<rev> (caret) Notation
           To exclude commits reachable from a commit, a prefix ^ notation
           is used. E.g.  ^r1 r2 means commits reachable from r2 but exclude
           the ones reachable from r1 (i.e.  r1 and its ancestors).

   Dotted Range Notations
       The .. (two-dot) Range Notation
           The ^r1 r2 set operation appears so often that there is a
           shorthand for it. When you have two commits r1 and r2 (named
           according to the syntax explained in SPECIFYING REVISIONS above),
           you can ask for commits that are reachable from r2 excluding
           those that are reachable from r1 by ^r1 r2 and it can be written
           as r1..r2.

       The ... (three dot) Symmetric Difference Notation
           A similar notation r1...r2 is called symmetric difference of r1
           and r2 and is defined as r1 r2 --not $(git merge-base --all r1
           r2). It is the set of commits that are reachable from either one
           of r1 (left side) or r2 (right side) but not from both.

       In these two shorthand notations, you can omit one end and let it
       default to HEAD. For example, origin.. is a shorthand for
       origin..HEAD and asks "What did I do since I forked from the origin
       branch?" Similarly, ..origin is a shorthand for HEAD..origin and asks
       "What did the origin do since I forked from them?" Note that .. would
       mean HEAD..HEAD which is an empty range that is both reachable and
       unreachable from HEAD.

   Other <rev>^ Parent Shorthand Notations
       Three other shorthands exist, particularly useful for merge commits,
       for naming a set that is formed by a commit and its parent commits.

       The r1^@ notation means all parents of r1.

       The r1^! notation includes commit r1 but excludes all of its parents.
       By itself, this notation denotes the single commit r1.

       The <rev>^-{<n>} notation includes <rev> but excludes the <n>th
       parent (i.e. a shorthand for <rev>^<n>..<rev>), with <n> = 1 if not
       given. This is typically useful for merge commits where you can just
       pass <commit>^- to get all the commits in the branch that was merged
       in merge commit <commit> (including <commit> itself).

       While <rev>^<n> was about specifying a single commit parent, these
       three notations also consider its parents. For example you can say
       HEAD^2^@, however you cannot say HEAD^@^2.

REVISION RANGE SUMMARY         top

       <rev>
           Include commits that are reachable from <rev> (i.e. <rev> and its
           ancestors).

       ^<rev>
           Exclude commits that are reachable from <rev> (i.e. <rev> and its
           ancestors).

       <rev1>..<rev2>
           Include commits that are reachable from <rev2> but exclude those
           that are reachable from <rev1>. When either <rev1> or <rev2> is
           omitted, it defaults to HEAD.

       <rev1>...<rev2>
           Include commits that are reachable from either <rev1> or <rev2>
           but exclude those that are reachable from both. When either
           <rev1> or <rev2> is omitted, it defaults to HEAD.

       <rev>^@, e.g. HEAD^@
           A suffix ^ followed by an at sign is the same as listing all
           parents of <rev> (meaning, include anything reachable from its
           parents, but not the commit itself).

       <rev>^!, e.g. HEAD^!
           A suffix ^ followed by an exclamation mark is the same as giving
           commit <rev> and then all its parents prefixed with ^ to exclude
           them (and their ancestors).

       <rev>^-{<n>}, e.g. HEAD^-, HEAD^-2
           Equivalent to <rev>^<n>..<rev>, with <n> = 1 if not given.

       Here are a handful of examples using the Loeliger illustration above,
       with each step in the notation’s expansion and selection carefully
       spelt out:

           Args   Expanded arguments    Selected commits
           D                            G H D
           D F                          G H I J D F
           ^G D                         H D
           ^D B                         E I J F B
           ^D B C                       E I J F B C
           C                            I J F C
           B..C   = ^B C                C
           B...C  = B ^F C              G H D E B C
           B^-    = B^..B
                  = ^B^1 B              E I J F B
           C^@    = C^1
                  = F                   I J F
           B^@    = B^1 B^2 B^3
                  = D E F               D G H E F I J
           C^!    = C ^C^@
                  = C ^C^1
                  = C ^F                C
           B^!    = B ^B^@
                  = B ^B^1 ^B^2 ^B^3
                  = B ^D ^E ^F          B
           F^! D  = F ^I ^J D           G H D F

PARSEOPT         top

       In --parseopt mode, git rev-parse helps massaging options to bring to
       shell scripts the same facilities C builtins have. It works as an
       option normalizer (e.g. splits single switches aggregate values), a
       bit like getopt(1) does.

       It takes on the standard input the specification of the options to
       parse and understand, and echoes on the standard output a string
       suitable for sh(1) eval to replace the arguments with normalized
       ones. In case of error, it outputs usage on the standard error
       stream, and exits with code 129.

       Note: Make sure you quote the result when passing it to eval. See
       below for an example.

   Input Format
       git rev-parse --parseopt input format is fully text based. It has two
       parts, separated by a line that contains only --. The lines before
       the separator (should be one or more) are used for the usage. The
       lines after the separator describe the options.

       Each line of options has this format:

           <opt-spec><flags>*<arg-hint>? SP+ help LF

       <opt-spec>
           its format is the short option character, then the long option
           name separated by a comma. Both parts are not required, though at
           least one is necessary. May not contain any of the <flags>
           characters.  h,help, dry-run and f are examples of correct
           <opt-spec>.

       <flags>
           <flags> are of *, =, ?  or !.

           ·   Use = if the option takes an argument.

           ·   Use ?  to mean that the option takes an optional argument.
               You probably want to use the --stuck-long mode to be able to
               unambiguously parse the optional argument.

           ·   Use * to mean that this option should not be listed in the
               usage generated for the -h argument. It’s shown for
               --help-all as documented in gitcli(7).

           ·   Use !  to not make the corresponding negated long option
               available.

       <arg-hint>
           <arg-hint>, if specified, is used as a name of the argument in
           the help output, for options that take arguments.  <arg-hint> is
           terminated by the first whitespace. It is customary to use a dash
           to separate words in a multi-word argument hint.

       The remainder of the line, after stripping the spaces, is used as the
       help associated to the option.

       Blank lines are ignored, and lines that don’t match this
       specification are used as option group headers (start the line with a
       space to create such lines on purpose).

   Example
           OPTS_SPEC="\
           some-command [options] <args>...

           some-command does foo and bar!
           --
           h,help    show the help

           foo       some nifty option --foo
           bar=      some cool option --bar with an argument
           baz=arg   another cool option --baz with a named argument
           qux?path  qux may take a path argument but has meaning by itself

             An option group Header
           C?        option C with an optional argument"

           eval "$(echo "$OPTS_SPEC" | git rev-parse --parseopt -- "$@" || echo exit $?)"

   Usage text
       When "$@" is -h or --help in the above example, the following usage
       text would be shown:

           usage: some-command [options] <args>...

               some-command does foo and bar!

               -h, --help            show the help
               --foo                 some nifty option --foo
               --bar ...             some cool option --bar with an argument
               --baz <arg>           another cool option --baz with a named argument
               --qux[=<path>]        qux may take a path argument but has meaning by itself

           An option group Header
               -C[...]               option C with an optional argument

SQ-QUOTE         top

       In --sq-quote mode, git rev-parse echoes on the standard output a
       single line suitable for sh(1) eval. This line is made by normalizing
       the arguments following --sq-quote. Nothing other than quoting the
       arguments is done.

       If you want command input to still be interpreted as usual by git
       rev-parse before the output is shell quoted, see the --sq option.

   Example
           $ cat >your-git-script.sh <<\EOF
           #!/bin/sh
           args=$(git rev-parse --sq-quote "$@")   # quote user-supplied arguments
           command="git frotz -n24 $args"          # and use it inside a handcrafted
                                                   # command line
           eval "$command"
           EOF

           $ sh your-git-script.sh "a b'c"

EXAMPLES         top

       ·   Print the object name of the current commit:

               $ git rev-parse --verify HEAD

       ·   Print the commit object name from the revision in the $REV shell
           variable:

               $ git rev-parse --verify $REV^{commit}

           This will error out if $REV is empty or not a valid revision.

       ·   Similar to above:

               $ git rev-parse --default master --verify $REV

           but if $REV is empty, the commit object name from master will be
           printed.
