The first argument is the _priority_ value to be used. The other arguments are interpreted as process IDs (by default), process group IDs, user IDs, or user names. *renice*'ing a process group causes all processes in the process group to have their scheduling priority altered. *renice*'ing a user causes all processes owned by the user to have their scheduling priority altered. + +If no *-n*, *--priority* or *--relative* option is used, then the priority is set as *absolute*. + +== OPTIONS + +*-n* _priority_:: +Specify the *absolute* or *relative* (depending on environment variable POSIXLY_CORRECT) scheduling _priority_ to be used for the process, process group, or user. Use of the option *-n* is optional, but when used, it must be the first argument. See *NOTES* for more information. + +*--priority* _priority_:: +Specify an *absolute* scheduling _priority_. _Priority_ is set to the given value. This is the default, when no option is specified. + +*--relative* _priority_:: +Specify a *relative* scheduling _priority_. Same as the standard POSIX *-n* option. _Priority_ gets _incremented/decremented_ by the given value. + +*-g*, *--pgrp*:: +Interpret the succeeding arguments as process group IDs. + +*-p*, *--pid*:: +Interpret the succeeding arguments as process IDs (the default). + +*-u*, *--user*:: +Interpret the succeeding arguments as usernames or UIDs. + +include::man-common/help-version.adoc[] + +== FILES + +_/etc/passwd_:: +to map user names to user IDs + +== NOTES + +Users other than the superuser may only alter the priority of processes they own. Furthermore, an unprivileged user can only _increase_ the "nice value" (i.e., choose a lower priority) and such changes are irreversible unless (since Linux 2.6.12) the user has a suitable "nice" resource limit (see *ulimit*(1p) and *getrlimit*(2)). + +The superuser may alter the priority of any process and set the priority to any value in the range -20 to 19. Useful priorities are: 19 (the affected processes will run only when nothing else in the system wants to), 0 (the "base" scheduling priority), anything negative (to make things go very fast). + +For historical reasons in this implementation, the *-n* option did not follow the POSIX specification. Therefore, instead of setting a *relative* priority, it sets an *absolute* priority by default. As this may not be desirable, this behavior can be controlled by setting the environment variable POSIXLY_CORRECT to be fully POSIX compliant. See the *-n* option for details. See *--relative* and *--priority* for options that do not change behavior depending on environment variables. + +== HISTORY + +The *renice* command appeared in 4.0BSD. + +== EXAMPLES + +The following command would change the priority of the processes with PIDs 987 and 32, plus all processes owned by the users daemon and root: + +*renice +1 987 -u daemon root -p 32* + +== SEE ALSO + +*nice*(1), +*chrt*(1), +*getpriority*(2), +*setpriority*(2), +*credentials*(7), +*sched*(7) + +include::man-common/bugreports.adoc[] + +include::man-common/footer.adoc[] + +ifdef::translation[] +include::man-common/translation.adoc[] +endif::[] -- cgit v1.2.3
