NAME

renice - change the priority of a running program  

SYNOPSIS

renice [{+-}inc] [=prio] pid ...  

DESCRIPTION

Renice modifies the kernel's internal process table to change the 'nice' value of the listed process IDs. The priority may be increased, decreased, or set to an absolute number. Only the super-user can increase the priority of a process, or change the priority of another user's process.  

OPTIONS

Giving -inc causes the priority to decrease by `inc'. Giving +inc causes the priority to increase by `inc'. Giving =prio causes the priority to be set to `prio'. The changes to the priority may be re-specified between process IDs. The default change is to add 5 to the 'niceness' of the processes (decrease its priority by 5).  

EXAMPLES

$ nroff -man -T37 renice.1 > /tmp/renice.manpage &
[1] 1234
renice 1234
These commands start a nroff in the background, and then change its priority so that it will not slow down work done in the foreground. The same effect would have resulted from typing 'nice' before the nroff command, but this example assumes that the user 'forgot' to lower the priority until the program was already running.
