NICE(1)                 GENIX Programmer's Manual                 NICE(1)



      NAME
           nice, nohup - run a command at low priority (sh only)

      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.  The syntax of nice is also
           different.

      FILES
           nohup.out standard output and standard error file under nohup

      SEE ALSO
           csh(1), nice(2), renice(8)

      DIAGNOSTICS
           Nice returns the exit status of the subject command.

      BUGS
           Nice and nohup are particular to sh(1).  If  you  use  csh(1),  then
           commands  executed  with "&" are automatically immune to hangup sig-
           nals while in the background.  There  is  a  builtin  command  nohup
           which  provides  immunity  from  terminate, but it does not redirect
           output to nohup.out.

           Nice is built into csh(1) with  a  slightly  different  syntax  than
           described  here.   The  form  "nice +10" nices to positive nice, and
           "nice -10" can be used by the super-user to give a process  more  of
           the processor.
