If no -n, --priority or --relative option is used, then the priority is set as absolute. -n ( POSIXLY_CORRECT) , , . -n, , . . , . --priority Specify an absolute scheduling priority. Priority is set to the given value. This is the default, when no option is specified. --relative Specify a relative scheduling priority. Same as the standard POSIX -n option. Priority gets incremented/decremented by the given value. -g, --pgrp . -p, --pid ( ). -u, --user . -h, --help . -V, --version . /etc/passwd ' , , , . , << nice>> ( ) , ( Linux 2.6.12) <> (. ulimit(1p) getrlimit(2)). - - -20 19. : 19 ( , ), 0 (<<>> ), - ' ( ). 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. renice ' 4.0BSD. 987 32, , daemon root: renice +1 987 -u daemon root -p 32 nice(1), chrt(1), getpriority(2), setpriority(2), credentials(7), sched(7) renice util-linux, Linux . util-linux 2.41 2025-03-29 RENICE(1)
