Parameter Syntax
- For unit commands the specified
- NAME should be the full name of the
- unit, or an abbreviated name which is automatically extended with
- the .service suffix.
- # systemctl start foo.service is equivalent to:
- # systemctl start foo
- Note that (absolute) paths to device nodes are automatically converted to device unit names, and other (absolute) paths to mount unit names.
- # systemctl status /dev/sda
-# systemctl status /home is equivalent to:
- # systemctl status dev-sda.device
-# systemctl status home.mount
-
- For unit file commands the
- specified NAME should be the full name
- of the unit file, or the absolute path to the unit file.
- # systemctl link /path/to/foo.service
-
+ Unit ommands listed above take either a single unit name
+ (designated as NAME), or multiple
+ unit specifications (designated as
+ PATTERN...). In the first case, the
+ unit name with or without a suffix must be given. If the suffix
+ is not specified, systemctl will append a suitable suffix,
+ .service by default, and a type-specific
+ suffix in case of commands which operate only on specific unit
+ types. For example,
+ # systemctl start sshd and
+ # systemctl start sshd.service
+ are equivalent, as are
+ # systemctl isolate snapshot-11
+ and
+ # systemctl isolate snapshot-11.snapshot
+ Note that (absolute) paths to device nodes are automatically
+ converted to device unit names, and other (absolute) paths to
+ mount unit names.
+ # systemctl status /dev/sda
+# systemctl status /home
+ are equivalent to:
+ # systemctl status dev-sda.device
+# systemctl status home.mount
+ In the second case, shell-style globs will be matched against
+ currently loaded units; literal unit names, with or without
+ a suffix, will be treated as in the first case. This means that
+ literal unit names always refer to exactly one unit, but globs
+ may match zero units and this is not considered an error.
+
+ Glob patterns use
+ fnmatch3,
+ so normal shell-style globbing rules are used, and
+ *, ?,
+ [] may be used. See
+ glob7
+ for more details. The patterns are matched against the names of
+ currently loaded units, and patterns which do not match anything
+ are silently skipped. For example:
+ # systemctl stop sshd@*.service
+ will stop all sshd@.service instances.
+
+
+ For unit file commands, the specified
+ NAME should be the full name of the
+ unit file, or the absolute path to the unit file:
+ # systemctl enable foo.service
+ or
+ # systemctl link /path/to/foo.service
