|
|
|
43ff24c |
+ escape strings for inclusion in systemd unit

43ff24c |
+ escaping of strings.</para>
|

43ff24c |

|
|

43ff24c |
+ <para>The command takes any number of strings on the
|
|
|
43ff24c |
+ command line, and will process them individually, one

|
43ff24c |
+ after the other. It will output them separated by

43ff24c |

43ff24c |

|
|

43ff24c |
+ passed, unless <option>--unescape</option> is passed
|
|
|
43ff24c |
+ which results in the inverse operation being
|
|
|
43ff24c |
+ applied. If <option>--mangle</option> a special mode
|
|
|
43ff24c |
+ of escaping is applied instead, which assumes a string
|
|
|
43ff24c |
+ to be already escaped but will escape everything that
|
|
|
43ff24c |
+ appears obviously non-escaped.</para>
