<title>Description</title>
<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>
<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. Takes one of the unit types
supported by systemd, such as
<literal>.service</literal> or
<literal>.mount</literal>. May not be
used in conjunction with
<option>--template=</option>,
<option>--unescape</option> or
<option>--mangle</option>.</para></listitem>
</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>
May not be used in conjunction with
<option>--suffix=</option>,
<option>--unescape</option> or
<option>--mangle</option>.</para></listitem>
</varlistentry>
<varlistentry>
<term><option>--path</option></term>
<term><option>-p</option></term>
<listitem><para>When escaping or
unescaping a string, assume it refers
to a file system path. This enables
special processing of the initial
<literal>/</literal> of the
path.</para></listitem>
</varlistentry>
<varlistentry>
<term><option>--unescape</option></term>
<listitem><para>Instead of escaping
the specified strings, undo the
escaping, reversing the operation. May
not be used in conjunction with
<option>--suffix=</option>,
<option>--template=</option> or
<option>--mangle</option>.</para></listitem>
</varlistentry>
<varlistentry>
<term><option>--mangle</option></term>
<listitem><para>Like
<option>--escape</option>, but only
escape characters that are obviously
not escaped yet, and possibly
automatically append an appropriate
unit type suffix to the string. May
not be used in conjunction with
<option>--suffix=</option>,
<option>--template=</option> or
<option>--unescape</option>.</para></listitem>

<title>Examples</title>
<para>Escape a single string:</para>
<programlisting>$ systemd-escape 'Hallöchen, Meister'
Hall\xc3\xb6chen\x2c\x20Meister</programlisting>
<para>To undo escaping on a single string:</para>
<programlisting>$ systemd-escape -u 'Hall\xc3\xb6chen\x2c\x20Meister'
Hallöchen, Meister</programlisting>
<para>To generate the mount unit for a path:</para>
<programlisting>$ systemd-escape -p --suffix=mount "/tmp//waldi/foobar/"
tmp-waldi-foobar.mount</programlisting>
<para>To generate instance names of three strings</para>
<programlisting>$ systemd-escape --template=systemd-nspawn@.service 'My Container 1' 'containerb' 'container/III'
systemd-nspawn@My\x20Container\x201.service systemd-nspawn@containerb.service systemd-nspawn@container-III.service</programlisting>

<title>Exit status</title>
<para>On success, 0 is returned, a non-zero failure
code otherwise.</para>
