Cisco ASA 5500 Series Configuration Guide using the CLI
Appendix A 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 conventions listed in Table A-1 .
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 ASA 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 ASA permits up to 512 characters in a command; additional characters are ignored.
