Syntax Description
!!
Repeats the previous command.
!<n>
Repeats the command line numbered n .
! –<n>
Repeats the command whose number is the current command number minus n . The
current command number is printed on the screen preceding the prompt. For
example, if the current command is 100 and
n is 2, command number 98 is repeated.
!<string>
Repeats the most recent command that starts with string . The SHow History command
might display the following commands:
166 setdefault !1 -path control = enabled
167 show -path configuration
168 show history
169 set screenlength = 23
170 setdefault -bridge control = bridge
171 show statistics ?
If you enter !setd at the prompt, the most recent occurrence of the SETDefault
command (setd -br cont = b, number 170) is executed.
!?<string>
Repeats the most recent command containing string .
^<string1>
^<string1>^<string2>
Repeats the most recent command that contains string1 . If string2 is specified, it
substitutes for string1 in that command. For example, if you entered this SETDefault
command with a typing mistake:
seed welcomestring = “You are talking to the 3Com NETBuilder”
To repeat the command with the correct spelling of SETD, you do not need to reenter
the entire command. Enter the following command:
^seed^setd
The following command is displayed and executed:
setd welcomestring = “You are talking to the 3Com NETBuilder”
