NAME
       nice - set program priority

SYNOPSIS
       nice(incr)

DESCRIPTION
       This interface is obsoleted by setpriority(2).

       The  scheduling priority of the process is augmented by _i_n_c_r.  Positive
       priorities get less service than normal.  Priority 10 is recommended to
       users  who  wish to execute long-running programs without flak from the
       administration.

       Negative increments are ignored except on  behalf  of  the  super-user.
       The priority is limited to the range -20 (most urgent) to 20 (least).

       The priority of a process is passed to a child process by _f_o_r_k(2).  For
       a privileged process to return  to  normal  priority  from  an  unknown
       state,  _n_i_c_e  should be called successively with arguments -40 (goes to
       priority -20 because of truncation), 20 (to get to 0), then 0 (to main‐
       tain compatibility with previous versions of this call).
