NAME

renice − alter priority of running process by changing nice

SYNOPSIS

renice pid [ priority ]

DESCRIPTION

Renice can be used by the super-user to alter the priority of a running process.  By default, the nice of the process is made “19” which means that it will run only when nothing else in the system wants to.  This can be used to nail long running processes which are interfering with interactive work. 

Renice can be given a second argument to choose a nice other than the default.  Negative nices can be used to make things go very fast.

BUGS

If you make the nice very negative, then the process cannot be interrupted.  To regain control you must put the nice back (e.g. to 0.)
