-.TH NICE 1
-.SH NAME
-nice \- invoke command with higher or lower scheduling priority
-.SH SYNOPSIS
-\fBnice\fP [\fB\-n\fP increment] \fIutility\fP [\fIargument\fP...]
-.SH DESCRIPTION
-The
-.B nice
-utility runs \fIutility\fP at a different scheduling priority than
-the default. The nicer the process is to others (the higher the
-increment), the less favourable the scheduling is. Super-users
-can give a negative increment, meaning scheduling is more favourable
-than the default.
-.SH OPTIONS
-.TP
-.B \-n \fIincrement
-the increment value sets how nice the invoked command will be. 0 is
-the same priority as regular processes. 10 is the default.
-The range is -20 to 20.
-.SH SEE ALSO
-getpriority(2), setpriority(2)
