nice: Run a command with modified scheduling priority
nice prints or modifies the scheduling priority of a job.
nice [option]... [command [arg]...]
If no arguments are given,
nice prints the current scheduling
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. You must have appropriate privileges to specify a negative
adjustment. The priority can be adjusted by
nice over the range
of -20 (the highest priority) to 19 (the lowest).
Because most shells have a built-in command by the same name, using the unadorned command name in a script or interactively may get you different functionality than that described here.
The program accepts the following option. Also see 2. Common options.
On older systems,
nice supports an obsolete option
`-adjustment'. POSIX 1003.1-2001 (see section 2.5 Standards conformance) does not allow this; use `-n adjustment'
