Within subcommands, typing Enter or Return at an empty prompt returns you to the main 
command. 

You can use the Control-C keyboard shortcut at any time within a subcommand to 
immediately exit return to the top level of the CLI.

History

The CLI keeps a history of all commands you type during a session. Use the Up and Down 
arrow keys on your keyboard, or the Control-P and Control-N key combinations, to scroll 
through a running list of the recently-used commands. 

Command Completion

The IronPort AsyncOS CLI supports command completion. You can type the first few letters of 
some commands followed by the Tab key, and the CLI completes the string for unique 
commands. If the letters you entered are not unique among commands, the CLI “narrows” the 
set. For example:

For both the history and file completion features of the CLI, you must type Enter or Return to 
invoke the command. 

Configuration Changes

You can make configuration changes to IronPort AsyncOS while email operations proceed 
normally. 

Configuration changes will not take effect until you complete the following steps:

1. Issue the 

commit

 command at the command prompt.

2. Give the 

commit

 command the input required.

3. Receive confirmation of the 

commit

 procedure at the CLI.

Changes to configuration that have not been committed will be recorded but not put into 
effect until the 

commit

 command is run. 

Note — Not all commands in AsyncOS require the 

commit

 command to be run. See Chapter 

1, “AsyncOS CLI Quick Reference Guide,” for a summary of commands that require commit 
to be run before their changes take effect.
