 The target component allows you to filter which minions should run the
 following function. The default filter is a glob on the minion id. For example::
 
-    salt '*' test.ping
-    salt '*.example.org' test.ping
+    # salt '*' test.ping
+    # salt '*.example.org' test.ping
 
 Targets can be based on minion system information using the Grains system::
 
-    salt -G 'os:Ubuntu' test.ping
+    # salt -G 'os:Ubuntu' test.ping
 
 .. seealso:: :doc:`Grains system </topics/targeting/grains>`
 
 Targets can be filtered by regular expression::
 
-    salt -E 'virtmach[0-9]' test.ping
+    # salt -E 'virtmach[0-9]' test.ping
 
 Targets can be explicitly specified in a list::
 
-    salt -L 'foo,bar,baz,quo' test.ping
+    # salt -L 'foo,bar,baz,quo' test.ping
 
 Or Multiple target types can be combined in one command::
     
-    salt -C 'G@os:Ubuntu and webser* or E@database.*' test.ping
+    # salt -C 'G@os:Ubuntu and webser* or E@database.*' test.ping
