Major Tom, This is Job Control - page 4
Acting Nice with the Linux System
The usage of
cron is pretty obvious: Repetitive automation. I
batch processing to really be helpful when you have a
job to run repetitively--say, a hardware information gathering script, for
example. I have used
at extensively to rerun cronjobs that may
have had a glitch or (as I mentioned earlier) simply to keep my terminal freed
up. If performance is not an issue and you wish to keep the terminal free,
just put the job(s) in the background.
With a little time and practice, using simple job control and batch processing can provide more productive time on your system.
