NAME

nice, nohup − run a command at low priority

SYNOPSIS

nice [ −number ] command [ arguments ]

nohup command [ arguments ]

DESCRIPTION

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 number 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 responding to interrupts by or stealing the input from the next person who logs in on the same terminal.
