9 systemd-escape [OPTIONS...] [STRING...]
10
12 systemd-escape may be used to escape strings for inclusion in systemd
13 unit names. The command may be used to escape and to undo escaping of
14 strings.
15
16 The command takes any number of strings on the command line, and will
17 process them individually, one after another. It will output them
18 separated by spaces to stdout.
19
20 By default, this command will escape the strings passed, unless
21 --unescape is passed which results in the inverse operation being
22 applied. If --mangle is given, a special mode of escaping is applied
23 instead, which assumes the string is already escaped but will escape
24 everything that appears obviously non-escaped.
25
26 For details on the escaping and unescaping algorithms see the relevant
27 section in systemd.unit(5).
28
30 The following options are understood:
31
32 --suffix=
33 Appends the specified unit type suffix to the escaped string. Takes
34 one of the unit types supported by systemd, such as "service" or
35 "mount". May not be used in conjunction with --template=,
36 --unescape or --mangle.
37
38 --template=
39 Inserts the escaped strings in a unit name template. Takes a unit
40 name template such as foobar@.service. May not be used in
41 conjunction with --suffix=, --unescape or --mangle.
42
43 --path, -p
44 When escaping or unescaping a string, assume it refers to a file
45 system path. This eliminates leading, trailing or duplicate "/"
46 characters and rejects "." and ".." path components. This is
47 particularly useful for generating strings suitable for unescaping
48 with the "%f" specifier in unit files, see systemd.unit(5).
49
50 --unescape, -u
51 Instead of escaping the specified strings, undo the escaping,
52 reversing the operation. May not be used in conjunction with
53 --suffix=, --template= or --mangle.
54
55 --mangle, -m
56 Like --escape, but only escape characters that are obviously not
57 escaped yet, and possibly automatically append an appropriate unit
58 type suffix to the string. May not be used in conjunction with
59 --suffix=, --template= or --unescape.
60
61 -h, --help
62 Print a short help text and exit.
63
64 --version
65 Print a short version string and exit.
66
68 To escape a single string:
69
70 $ systemd-escape 'Hallöchen, Meister'
71 Hall\xc3\xb6chen\x2c\x20Meister
72
73 To undo escaping on a single string:
74
75 $ systemd-escape -u 'Hall\xc3\xb6chen\x2c\x20Meister'
76 Hallöchen, Meister
77
78 To generate the mount unit for a path:
79
80 $ systemd-escape -p --suffix=mount "/tmp//waldi/foobar/"
81 tmp-waldi-foobar.mount
82
83 To generate instance names of three strings:
84
85 $ systemd-escape --template=systemd-nspawn@.service 'My Container 1' 'containerb' 'container/III'
86 systemd-nspawn@My\x20Container\x201.service systemd-nspawn@containerb.service systemd-nspawn@container-III.service
87
89 On success, 0 is returned, a non-zero failure code otherwise.
