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 priority. Some shells may provide a builtin nice command which is similar or identi- cal to this utility. Consult the builtin(1) manual page. ENVIRONMENT The PATH environment variable is used to locate the requested utility if the name contains no `/' characters. EXIT STATUS 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. EXAMPLES Execute utility `date' at priority 5 assuming the priority of the shell is 0: nice -n 5 date Execute utility `date' at priority -19 assuming the priority of the shell is 0 and you are the super-user: nice -n 16 nice -n -35 date COMPATIBILITY The traditional -increment option has been deprecated but is still sup- ported. SEE ALSO builtin(1), csh(1), idprio(1), rtprio(1), getpriority(2), setpriority(2), renice(8) STANDARDS The nice utility conforms to IEEE Std 1003.1-2001 ("POSIX.1").
