<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 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>
|
|
|
|
<para>For details on the escaping and unescaping algorithms see the relevant section in
|
|
<citerefentry><refentrytitle>systemd.unit</refentrytitle><manvolnum>5</manvolnum></citerefentry>.</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

<listitem><para>When escaping or unescaping a string, assume it refers to a file system path. This eliminates
|
|
leading, trailing or duplicate <literal>/</literal> characters and rejects <literal>.</literal> and
|
|
<literal>..</literal> path components. This is particularly useful for generating strings suitable for
|
|
unescaping with the <literal>%f</literal> specifier in unit files, see

<para>To escape a single string:</para>

<programlisting>$ systemd-escape 'Hallöchen, Meister'

Hall\xc3\xb6chen\x2c\x20Meister</programlisting>

Hallöchen, Meister</programlisting>

<para>To generate instance names of three strings:</para>
