Word designators are used to select desired words from the event.
A ‘:
’ separates the event specification from the word designator. It
may be omitted if the word designator begins with a ‘^
’, ‘$
’,
‘*
’, ‘-
’, or ‘%
’. Words are numbered from the beginning
of the line, with the first word being denoted by 0 (zero). Words are
inserted into the current line separated by single spaces.
For example,
!!
!!:$
!$
.!fi:2
fi
.Here are the word designators:
0 (zero)
0
th word. For many applications, this is the command word.n
n
th word.^
$
%
?string?
’ search.x-y
-y
’ abbreviates ‘0-y
’.*
0
th. This is a synonym for ‘1-$
’. It is not an error to use ‘*
’ if there is just one word in the event; the empty string is returned in that case.x*
x-$
’x-
x-$
’ like ‘x*
’, but omits the last word.If a word designator is supplied without an event specification, the previous command is used as the event.
