SYNOPSIS
systemd-escape [OPTIONS...] [STRING...]
DESCRIPTION
systemd-escape 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.
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.
By default, this command will escape the strings passed, unless --unescape is passed which results in the inverse operation being applied. If --mangle 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.
OPTIONS
The following options are understood:
--suffix=
Appends the specified unit type suffix to the escaped
string. Takes one of the unit types supported by systemd, such as
".service" or ".mount". May not be used in conjunction
with --template=, --unescape or --mangle.
--template=
Inserts the escaped strings in a unit name template.
Takes a unit name template such as foobar@.service May not be used in
conjunction with --suffix=, --unescape or --mangle.
--path, -p
When escaping or unescaping a string, assume it refers to
a file system path. This enables special processing of the initial
"/" of the path.
--unescape
Instead of escaping the specified strings, undo the
escaping, reversing the operation. May not be used in conjunction with
--suffix=, --template= or --mangle.
--mangle
Like --escape, 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
--suffix=, --template= or --unescape.
-h, --help
Print a short help text and exit.
--version
Print a short version string and exit.
EXAMPLES
Escape a single string:
$ systemd-escape 'Hallöchen, Meister' Hall\xc3\xb6chen\x2c\x20Meister
To undo escaping on a single string:
$ systemd-escape -u 'Hall\xc3\xb6chen\x2c\x20Meister' Hallöchen, Meister
To generate the mount unit for a path:
$ systemd-escape -p --suffix=mount "/tmp//waldi/foobar/" tmp-waldi-foobar.mount
To generate instance names of three strings
$ 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
EXIT STATUS
On success, 0 is returned, a non-zero failure code otherwise.
