Using the CLI CLI Services

OmniSwitch 6250/6450 Switch Management Guide May 2012 page 6-12

Recalling the Previous Command Line

To recall the last command executed by the switch, press either the Up Arrow key or the !! (bang, bang)

command at the prompt and the previous command is displayed on your screen. You can execute the

command again by pressing Enter or you can edit it first by deleting or inserting characters.

In the following example, the ls command is used to list the contents of the /flash/switch directory of the

switch.

-> ls

Listing Directory /flash/switch:

drw 2048 Jan 1 1980 ./

drw 2048 Jan 3 19:23 ../

-rw 308 Jan 1 1980 banner_default.txt

9850880 bytes free

To enter this same command again, use the Up Arrow key. The ls command appears at the prompt. To

issue the ls command, press Enter.

-> ls

The Up Arrow key and the !! (bang, bang) command displays the last command line entered even if the

command was rejected by the switch.

For more details on using the !! command, refer to “Command History” on page 6-15.

Inserting Characters

To insert a character between characters already typed, use the Left and Right Arrow keys to place the

cursor into position, then type the new character. Once the command is correct, execute it by pressing

Enter. In the following example, the user enters the wrong syntax to execute the show microcode

command. The result is an error message.

-> show microcode

ERROR: flash: no such directory

To correct the syntax without retyping the entire command line, use the !! command to recall the previous

syntax. Then, use the Left Arrow key to position the cursor between the “r” and the “c” characters. To

insert the missing character, type “o”.

-> !!

-> show microcode

To execute the corrected command, press Enter.
