Appendix C Using the Command-Line Interface
Syntax Formatting
From global configuration mode, some commands enter a command-specific configuration mode.
All user EXEC, privileged EXEC, global configuration, and command-specific configuration
commands are available in this mode. For example, the
interface command enters interface
configuration mode. The prompt changes to the following:
hostname(config-if)#
hostname/context(config-if)#
Syntax Formatting
Command syntax descriptions use the following conventions:
Abbreviating Commands
You can abbreviate most commands down to the fewest unique characters for a command; for example,
you can enter
wr t
to view the configuration instead of entering the full command
write terminal
, or
you can enter
en
to start privileged mode and
con
f t to start configuration mode. In addition, you can
enter
0
to represent
0.0.0.0
.
Command-Line Editing
The security appliance uses the same command-line editing conventions as Cisco IOS software. You can
view all previously entered commands with the
show history command or individually with the up arrow
or ^p command. Once you have examined a previously entered command, you can move forward in the
list with the down arrow or ^n command. When you reach a command you wish to reuse, you can edit
it or press the Enter key to start it. You can also delete the word to the left of the cursor with ^w , or erase
the line with ^u .
The security appliance permits up to 512 characters in a command; additional characters are ignored.
