nice — Run a command at a different priority
Format
Description
Options
Localization
nice [–n number] command-line nice [–number] command-line
tcsh shell: nice [+number] [command]
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
commands, pipelines, command substitution, and other special structures.
nice in the tcsh shell
In the tcsh shell, nice sets the scheduling priority for the tcsh shell to number, or,
without number, to 4. With command, nice runs command at the appropriate
priority. The greater the number, the less cpu the process gets. The super-user may
specify negative priority by using:
nice -number ...
command is always executed in a sub-shell, and the restrictions placed on
commands in simple if statements apply. See “tcsh — Invoke a C shell” on page
626.
–n number
Lowers the current priority by number. On systems supporting higher
priorities, a user with appropriate privileges can 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.
nice uses the following localization environment variables:
v LANG
v LC_ALL
v LC_CTYPE
v LC_MESSAGES
v NLSPATH
See Appendix F for more information.
