- <para>For unit commands the specified
- <replaceable>NAME</replaceable> should be the full name of the
- unit, or an abbreviated name which is automatically extended with
- the <literal>.service</literal> suffix.
- <programlisting># systemctl start foo.service</programlisting> is equivalent to:
- <programlisting># systemctl start foo</programlisting>
- Note that (absolute) paths to device nodes are automatically converted to device unit names, and other (absolute) paths to mount unit names.
- <programlisting># systemctl status /dev/sda
-# systemctl status /home</programlisting> is equivalent to:
- <programlisting># systemctl status dev-sda.device
-# systemctl status home.mount</programlisting></para>
-
- <para>For unit file commands the

- of the unit file, or the absolute path to the unit file.
- <programlisting># systemctl link /path/to/foo.service</programlisting>

+ <para>Unit ommands listed above take either a single unit name
+ (designated as <replaceable>NAME</replaceable>), or multiple
+ unit specifications (designated as
+ <replaceable>PATTERN</replaceable>...). 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,
+ <literal>.service</literal> by default, and a type-specific
+ suffix in case of commands which operate only on specific unit
+ types. For example,
+ <programlisting># systemctl start sshd</programlisting> and
+ <programlisting># systemctl start sshd.service</programlisting>
+ are equivalent, as are
+ <programlisting># systemctl isolate snapshot-11</programlisting>
+ and
+ <programlisting># systemctl isolate snapshot-11.snapshot</programlisting>
+ Note that (absolute) paths to device nodes are automatically
+ converted to device unit names, and other (absolute) paths to
+ mount unit names.
+ <programlisting># systemctl status /dev/sda
+# systemctl status /home</programlisting>
+ are equivalent to:
+ <programlisting># systemctl status dev-sda.device
+# systemctl status home.mount</programlisting>
+ In the second case, shell-style globs will be matched against
+ currently loaded units, and 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.</para>
+
+ <para>Glob patterns use
+ <citerefentry><refentrytitle>fnmatch</refentrytitle><manvolnum>3</manvolnum></citerefentry>,
+ so normal shell-style globbing rules are used, and
+ <literal>*</literal>, <literal>?</literal>,
+ <literal>[]</literal> may be used. See
+ <citerefentry><refentrytitle>glob</refentrytitle><manvolnum>7</manvolnum></citerefentry>
+ for more details. The patterns are matched against the names of
+ currently loaded units, and patterns which don't match anything
+ are silently skipped. For example:
+ <programlisting># systemctl stop sshd@*.service</programlisting>
+ will stop all <filename>sshd@.service</filename> instances.
+ </para>
+
+ <para>For unit file commands, the specified
+ <replaceable>NAME</replaceable> should be the full name of the
+ unit file, or the absolute path to the unit file:
+ <programlisting># systemctl enable foo.service</programlisting>
+ or
+ <programlisting># systemctl link /path/to/foo.service</programlisting>
+ </para>
