nice — run a program with modified scheduling priority

Examples (TL;DR)


nice [OPTION] [COMMAND [ARG]...]


Run COMMAND with an adjusted niceness, which affects process scheduling. With no COMMAND, print the current niceness.  Niceness values range from -20 (most favorable to the process) to 19 (least favorable to the process).

Mandatory arguments to long options are mandatory for short options too.

-n, --adjustment=N

add integer N to the niceness (default 10)

NOTE: your shell may have its own version of nice, which usually supersedes the version described here.  Please refer to your shell's documentation for details about the options it supports.
