NICE(1L)

NAME
nice - run a program with modified scheduling priority

SYNOPSIS
nice [-n adjustment] [-adjustment] [--adjustment=adjustment] [command [arg...]]

DESCRIPTION
This manual page documents the GNU version of nice. If no arguments are given, nice prints the current sheduling priority, which it inherited. Otherwise, nice runs the given command with its scheduling priority adjusted. If no adjustment is given, the priority of the command is incremented by 10. The superuser can specify a negative adjustment. The priority can be adjusted by nice over the range of -20 (the highest priority) to 19 (the lowest).

  OPTIONS

-n adjustment, -adjustment, --adjustment=adjustment
    Add adjustment instead of 10 to the command's priority.

The long-named options can be introduced with `+' as well as `--', for compatibility with previous releases. Eventually support for `+' will be removed, because it is incompatible with the POSIX.2 standard.
