The command may be used to escape and to undo escaping of strings.</para> <para>The command takes any number of strings on the command line, and will process them individually, one after another. It will output them separated by spaces to stdout.</para> <para>By default, this command will escape the strings passed, unless <option>--unescape</option> is passed which results in the inverse operation being applied. If <option>--mangle</option> is given, a special mode of escaping is applied instead, which assumes the string is already escaped but will escape everything that appears obviously non-escaped.</para> </refsect1> <refsect1> <title>Options</title> <para>The following options are understood:</para> <variablelist> <varlistentry> <term><option>--suffix=</option></term> <listitem><para>Appends the specified unit type suffix to the escaped string.
