VI EXECUTION

While writing shell scripts in vi, have you ever considered the time wasted by going in and out of vi to test your commands by executing them on the command line.

To increase your productivity, it would be a lot quicker if you could execute these commands from within the editor and view their output before writing them to your script.

This is possible and quite straight forward. Enter the following within vi

:!testscript

(i.e. colon exclamation mark)

Then enter your command as you would at the $ or # prompt.

The command executes, the result is displayed and you are propmted to press return to continue.
