describes. For details, see the MPE/iX NOTES section at the end of this man page.
nice runs a command at a different priority than usual. Normally, nice lowers the current
priority by 10.
The command-line must invoke a single utility command, without using compound com-
mands, pipelines, command substitution, and other special structures.
Options

user with appropriate privileges may use nice to increase priority by specifying a
negative value for number. For example,
nice -n -3 command
runs the command with an increased priority of 3.
–number
is an obsolescent version of –n number.

mand-line.
