Abbreviating a Command
You can abbreviate commands and keywords to the number of characters that allow a unique
abbreviation.
You can abbreviate the show command to sh. After entering the command at the system prompt, press
Return to execute the command.
Completing a Partial Command
The Tab key allows you to use the command-completion feature. When you enter a unique partial
character string and press the Tab key, the system completes the command or keyword on the command
line.
For example, if you enter co and press the Tab key, the system completes the command as configure
because it is the only command that matches the criteria.
