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
     incrementing 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 priority.

     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 iden‐
     tical 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.

STANDARDS
