Unix Tip #4392- March 21, 2014

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.
