Telecom CCNA: - Command Shortcuts
http://telecomccna.blogspot.com/2008/06/command-shortcuts.html
Saturday, June 28, 2008. Take a look at this command. It backs up the current configuration and saves it so that the router will use it next time it boots up:. That's a big hunk of typing. More typing means more time and more errors, so to save time, we can use. Truncation. As long as the truncation provides enough information for the IOS to figure out what command you are trying to enter, you can reduce the amount of typing you have to do, saving yourself time:. That's a big savings in typing effort.
