[ScreenOS] How to create aliases



Article ID: KB12290 KB Last Updated: 05 Oct 2019Version: 4.0

The purpose of this article is to provide instructions for creating aliases for the ScreenOS command line interface.


ScreenOS is capable of using alias commands similar to that found in most Linux command line shells. Aliases can be used to create a shorthand command for longer, more complex commands that are used repeatedly.


To create an alias for a command, log into the command line via the console port or SSH/Telnet.

Use the command:

set alias <alias command> <full command>


set alias db "get db stream"

The example above creates an alias called "db". When "db" is entered on the command line the command "get db stream", which retrieves the contents of the debug buffer, is executed.

Another example of using aliases is documented here below:-

You can use a 'show' command to display the equivalent of a 'get' command using the 'set alias' command. 


NS-> set alias ?
<string>             alias name (up to 16 characters)
NS-> set alias show ?
<string>             alias definition
NS-> set alias show get
NS-> show db str
