nice, nohup - run a command at low priority
nice [ -number ] command [ arguments ]
nohup command [ arguments ]
Nice executes command with low scheduling priority. If the number
argument is present, the priority is incremented (higher numbers mean
lower priorities) by that amount up to a limit of 20. The default num-
ber is 10.
The super-user may run commands with priority higher than normal by
using a negative priority, e.g. `--10'.
Nohup executes command immune to hangup and terminate signals from the
controlling terminal. The priority is incremented by 5. Nohup should
be invoked from the shell with `&' in order to prevent it from respond-
ing to interrupts by or stealing the input from the next person who
logs in on the same terminal.
