Bash shell problem

[gmorton]

Hi everyone

I've been trying all day to find out how to do the following and I'm having no luck. Any help would REALLY be appreciated.

I have a bash script that generates a log file, taking sar measurements at regular intervals in an endless loop. How can I assign a shortcut key that will call a function that I have written to do some cleen-up tasks before terminating. Control-c terminates my shell but, obviuosly, no clean-up is done. My function is quitter() and i've trieed the following, which doesn't work:

bind -x '"\C-q":quitter'

Thanks
Grant

look at trap, as you can direct the script to execute your stuff when your chosen keys are hit.

If you are running at regular intervals as a loop, why don't you cron the job? That way you can run your process with clean-up at whatever your intervals are. It's nice and tidy and built-in. You also don't need to be logged in.

As cdlvj says, the best way is trap.
Trap ^c and cleanup. That's pretty
standard.
