OmniSwitch AOS Release 6 Switch Management Guide

You can recall commands shown in the history list by using the exclamation point character (

) also called 

“bang”. To recall the command shown in the history list at number 4, enter !4 (bang, 4). The CLI will 
respond by printing the number four command at the prompt. Using the history list of commands above, 
the following would display:

-> !4

-> show temp 

You can recall the last command in the history list by issuing the 

 (bang bang) syntax. The CLI will 

respond by printing the last command in the history list (

) at the prompt as shown here.

-> !!

-> show history 

Note. When you use !n or !! to recall a command in the history list, you must press the Enter key to 
execute the command.

You can configure the number of history commands saved by the switch for display by the show history 
command. The range for the 

 value is 1 to 30. To view the history parameters, use the 

 command.

-> history size 30

-> show history parameters

History size: 30

CurrentSize: 10

Index Range: 1-10 

The values in this display are defined here:

• History Size: The number of commands the switch will save for display by the 

command.

• Current Size: The number of commands currently saved by the switch, ready for display by the 

 command.

• Index Range: This value indicates the index range of the commands for this CLI session currently 

stored in the history buffer.

In the above example, the switch is set to display 30 commands. However, when the show history 
parameters command was issued, only ten commands had yet been issued. Since only ten commands had 
been issued during the current login session, the index range shows 1 to 10. This is because the commands 
in the buffer are the first through the tenth commands issued during the current login session. 

Note. The Partial Keyword Completion feature described on 

 works within the CLI history buffer.
