Syntax Formatting

Command syntax descriptions use the following conventions:
Table C-1

bold
italics
[x]

[x | y]
{x | y}
[x {y | z}]

Abbreviating Commands

You can abbreviate most commands down to the fewest unique characters for a command; for example,
you can enter
you can enter
enter

Command-Line Editing

The FWSM 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 FWSM permits up to 512 characters in a command; additional characters are ignored.

Command Completion

To complete a command or keyword after entering a partial string, press the Tab key. The FWSM only
completes the command or keyword if the partial string matches only one command or keyword. For
example, if you enter s and press the Tab key, the FWSM does not complete the command because it
matches more than one command. However, if you enter dis, the Tab key completes the command
disable.
