systemd-escape(1)


NAME

   systemd-escape - Escape strings for usage in system unit names

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 eliminates leading, trailing or duplicate "/"
       characters and rejects "."  and ".."  path components.

   --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

   To escape a single string:

       $ systemd-escape 'Hallchen, Meister'
       Hall\xc3\xb6chen\x2c\x20Meister

   To undo escaping on a single string:

       $ systemd-escape -u 'Hall\xc3\xb6chen\x2c\x20Meister'
       Hallchen, 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.
