CPULIMIT

NAME

cpulimit -- limits the CPU usage of a process

SYNOPSIS

cpulimit TARGET [OPTIONS...]

DESCRIPTION

TARGET must be exactly one of these:
−p, −−pid=N

pid of the process

−e, −−exe=FILE

name of the executable program file

−P, −−path=PATH

absolute path name of the executable program file

OPTIONS
−l, −−limit=N

percentage of CPU allowed from 0 to 100 (mandatory)

−v, −−verbose

show control statistics

−z, −−lazy

exit if there is no suitable target process, or if it dies

−h, −−help

display this help and exit

EXAMPLES

Assuming you have started ‘foo −−bar‘ and you find out with top(1) or ps(1) that this process uses all your CPU time you can either
# cpulimit −e foo −l 50

limits the CPU usage of the process by acting on the executable program file (note: the argument "−−bar" is omitted)

# cpulimit −p 1234 −l 50

limits the CPU usage of the process by acting on its PID, as shown by ps(1)

# cpulimit −P /usr/bin/foo −l 50

same as −e but uses the absolute path name
