You can use your shell's own built-in job control, but my preference is
to use system schedulers for any lengthy processing.
Using shell job control allows you to access and monitor multiple tasks.
However:
- I tend to lose track of shells, particularly under X, where I may
have 26 windows open with sessions on three or four different
systems.
- Using shell job control means you'll get periodic output to your
screen. And may have to "rescue" jobs (run noninteractively, they'd
simply fail).
For quick jobs, I'll generally resort to using at or batch. A favorite
is:
$ echo 'command -args' | batch
...which submits a command and its argument to the batch processor. The
job runs when system load permits, and emails me a notification when
it's completed.
$ at now
> command -args
>^D
...is another alternative. I cron regular tasks.
There are also more sophisticated batch systems available, though I've
very limited experience with them.
