By default, the applicable processes -are specified by their process IDs. When a process group is specified -(see -.B -g -), the request applies to all processes in the process group. If the -requested increment would raise or lower the nice value of the -executed utility beyond its limits, then the limit whose value was -exceeded is used. When a user is reniced, the request applies to all -processes whose saved set-user-ID matches the user ID corresponding to -the user. Regardless of which options are supplied or any other factor, -renice does not alter the nice values of any process unless the user -requesting such a change has appropriate privileges to do so for the -specified process. If the user lacks appropriate privileges to perform -the requested action, the utility returns an error status. -The saved set-user-ID of the user's process is checked instead of its -effective user ID when renice attempts to determine the user ID of the -process in order to determine whether the user has appropriate privileges. -.SH OPTIONS -.TP -.B \-g -interpret all operands as unsigned decimal integer process group IDs. -.TP -.B \-n -.I increment -specify how the nice value of the specified process or processes -is to be adjusted. The increment option-argument is a positive or -negative decimal integer used to modify the nice value of the -specified process or processes. positive increment values cause a -lower nice value. Negative increment values may require appropriate -privileges and cause a higher nice value. -.TP -.B \-p -interpret all operands as unsigned decimal integer process IDs. -The -.B \-p -option is the default if no options are specified. -.TP -.B \-u -interpret all operands as users. If a user exists with a user name -equal to the operand, then the user ID of that user is used in further -processing. Otherwise, if the operand represents an unsigned decimal -integer, used as the numeric user ID of the user. -.SH EXIT VALUES -On successful completion 0 is returned, a value which is >0 is -returned on error. -.SH FILES -.TP -.I /etc/passwd -used to map user names to user ID's. -.SH CONFORMING TO -The -.B renice -utility is IEEE Std 1003.1-2001 (POSIX.1) compatible. -.SH EXAMPLES -.TP -.I "renice -n 5 -p 987 32" -.PP -Adjust the nice value so that process IDs 987 and 32 would have a -lower nice value. -.TP -.I "renice -n -4 -g 324 76" -.PP -Adjust the nice value so that group IDs 324 and 76 would have a -higher nice value, if the user has the appropriate privileges to do so. -.TP -.I "renice -n 4 -u 8 sas" -.PP -Adjust the nice value so that numeric user ID 8 and user sas would -have a lower nice value. -Useful nice value increments on historical systems include -19 or 20 (the affected processes run only when nothing else in the -system attempts to run) and any negative number -(to make processes run faster). -.SH AUTHOR -Written by Lorenzo Cogotti. -.SH SEE ALSO -.BR nice(1) +.Nm +utility is compliant with the +.St -p1003.1-2008 +specification.
