+
+ <para><command>systemd-escape</command> may be used to
+ escape strings for inclusion in systemd unit
+ names. 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 the other. 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> a special mode
+ of escaping is applied instead, which assumes a string
+ to be already escaped but will escape everything that
+ appears obviously non-escaped.</para>
+ </refsect1>

+ <title>Options</title>

+ <para>The following options are understood:</para>

+ <listitem><para>Appends the specified
+ unit type suffix to the escaped
+ string. Takes one of the unit types
+ supported by systemd, such as
+ <literal>.service</literal> or

+ <option>--template=</option>,
+ <option>--unescape</option> or

+ </varlistentry>
+
+ <varlistentry>
+ <term><option>--template=</option></term>
+
+ <listitem><para>Inserts the escaped
+ strings in a unit name template. Takes
+ a unit name template such as
+ <filename>foobar@.service</filename>

+ <option>--mangle</option>.</para></listitem>

+
+ <varlistentry>
+ <term><option>--unescape</option></term>
+
+ <listitem><para>Instead of escaping
