Command History and Re-Executing Commands
The
history
command displays up to 50 commands numbered in order with the most recently
executed command listed last. The following is a typical example of the
history
command.
1: view mpx.cmd
2: vlan
3: at
4: atvl
5: vimcvl
6: mcvl
7: vivl
8: fwtvl
9: xlat
10: history
In the example above, the
history
command is listed last because it is the one that was
executed most recently. If you want to re-execute the last command, enter two exclamation
points (
!!
). In the example above, you could re-execute the
history
command by entering
!!
at the system prompt.
You can also display a specific number of commands by entering
history
followed by a
number less than or equal to the number of commands in the history buffer. For example, if
you entered
history 5
in the example above you would see the following:
7: vivl
8: fwtvl
9: xlat
10: history
11:history 5
The
UI
also provides several other ways to re-execute earlier commands. For example, you
can re-execute a specific command shown in the
history
list by entering an exclamation point
(
!
) followed by the number to the left of that command shown in the
history
list. In the exam-
ple at the beginning of this section, entering
!2
would re-execute the
vlan
command.
You can also re-execute a command a set number of commands back by entering an excla-
mation point and a minus sign (
!-
) followed by that set number of commands back. In the
example at the beginning of this section, entering
!-3
would re-execute the
fwtvl
command.
