+      <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>

+# 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

+      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.
