+ <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>
