         is equivalent to:
 
                 perf script -f trace:<fields> -f sw:<fields> -f hw:<fields>
-    
+
         i.e., the specified fields apply to all event types if the type string
         is not given.
-    
+
         The arguments are processed in the order received. A later usage can
         reset a prior request. e.g.:
-    
+
                 -f trace: -f comm,tid,time,ip,sym
-    
+
         The first -f suppresses trace events (field list is ""), but then the
         second invocation sets the fields to comm,tid,time,ip,sym. In this case a
         warning is given to the user:
-    
+
                 "Overriding previous field request for all events."
-    
+
         Alternatively, consider the order:
-    
+
                 -f comm,tid,time,ip,sym -f trace:
-    
+
         The first -f sets the fields for all events and the second -f
         suppresses trace events. The user is given a warning message about
         the override, and the result of the above is that only S/W and H/W
         events are displayed with the given fields.
-    
+
         For the 'wildcard' option if a user selected field is invalid for an
         event type, a message is displayed to the user that the option is
         ignored for that type. For example:
-    
+
                 $ perf script -f comm,tid,trace
                 'trace' not valid for hardware events. Ignoring.
                 'trace' not valid for software events. Ignoring.
-    
+
         Alternatively, if the type is given an invalid field is specified it
         is an error. For example:
-    
+
         perf script -v -f sw:comm,tid,trace
         'trace' not valid for software events.
-    
+
         At this point usage is displayed, and perf-script exits.
-    
+
         Finally, a user may not set fields to none for all event types.
         i.e., -f "" is not allowed.
