Any relative filenames are resolved as if they are prefixed by <code><arg></code> and will be printed in that form.</p> <div class="paragraph"> <p>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:</p> </div> <div class="listingblock"> <div class="content"> <pre>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" -- "$@")"</pre> </div> </div> </dd> <dt class="hdlist1">--verify</dt> <dd> <p>Verify that exactly one parameter is provided, and that it can be turned into a raw 20-byte SHA-1 that can be used to access the object database. If so, emit it to the standard output; otherwise, error out.</p> <div class="paragraph"> <p>If you want to make sure that the output actually names an object in your object database and/or can be used as a specific type of object you require, you can add the <code>^{type}</code> peeling operator to the parameter. For example, <code>git rev-parse "$VAR^{commit}"</code> will make sure <code>$VAR</code> names an existing object that is a commit-ish (i.e. a commit, or an annotated tag that points at a commit). To make sure that <code>$VAR</code> names an existing object of any type, <code>git rev-parse "$VAR^{object}"</code> can be used.</p> </div> <div class="paragraph"> <p>Note that if you are verifying a name from an untrusted source, it is wise to use <code>--end-of-options</code> so that the name argument is not mistaken for another option.</p> </div> </dd> <dt class="hdlist1">-q</dt> <dt class="hdlist1">--quiet</dt> <dd> <p>Only meaningful in <code>--verify</code> mode.

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 <code>-S</code> with <em>git diff-*</em>). In contrast to the <code>--sq-quote</code> option, the command input is still interpreted as usual.</p> </dd> <dt class="hdlist1">--short[=length]</dt> <dd> <p>Same as <code>--verify</code> but shortens the object name to a unique prefix with at least <code>length</code> characters.
