Command Completion

To enter a command string, type a portion of the command string with a question mark (?) . The CLI returns all the possible commands words that start with the combination of characters entered.

VX# re?
reconfigure reset

The example above demonstrates that the string - re - is associated with two other commands that begin with the identical letter combination. Adding another letter to the entry string renders the entry unique enough to be associated with a single command, as demonstrated below.

VX# rec
TEST# reconfigure

To enable command completion, you only need to type enough characters to make the command entry unique.

Command Recall

To recall commands in the history buffer beginning with the most recent command, press Control+P . Repeat the key sequence to recall successively older commands.

To return to more recent commands in the history buffer after recalling commands with Control+P , press Control+N or the up and down arrows. Repeat the key sequence to recall successively more recent commands.

Showing Additional Arguments

If too few arguments are entered, the CLI responds with Incomplete command . Press Control+P to repeat the previous command entry. Then add a space and a question mark (?) to show the additional arguments.

VX# show alarm ?
catalogs Show the alarm catalog file settings
log Show the alarm log file settings
VX# show alarm

When no more arguments are needed, CLI indicate this with <cr>.

VX# show alarm log ?
&nbsp;VX# show alarm log
