NICE(1) General Commands Manual NICE(1) NAME nice -- execute a utility at an altered scheduling priority SYNOPSIS nice [-n increment] utility [argument ...] DESCRIPTION The nice utility runs utility at an altered scheduling priority, by incre- menting its "nice" value by the specified increment, or a default value of 10. The lower the nice value of a process, the higher its scheduling pri- ority. The superuser may specify a negative increment in order to run a utility with a higher scheduling prority. Some shells may provide a builtin nice command which is similar or identi- cal to this utility. Consult the builtin(1) manual page. EXAMPLES $ nice -n 5 date Execute utility `date' at priority 5 assuming the priority of the shell is 0. # nice -n 16 nice -n -35 date Execute utility `date' at priority -19 assuming the priority of the shell is 0 and you are the super-user. DIAGNOSTICS If utility is invoked, the exit status of nice is the exit status of utility. An exit status of 126 indicates utility was found, but could not be exe- cuted. An exit status of 127 indicates utility could not be found.

STANDARDS The nice utility conforms to IEEE Std 1003.1-2001 ("POSIX.1"). HISTORY A nice utility appeared in Version 4 AT&T UNIX. FreeBSD 4.7 June 6, 1993 NICE(1)
