cpulimit

linux

A tool to throttle the CPU usage of other processes.

Options (6)

-p, --pidboolean

Limit an existing process with PID 1234 to only use 25% of the CPU

Example: cpulimit {{[-p|--pid]}} {{1234}} {{[-l|--limit]}} {{25%}}

-l, --limitboolean

Limit an existing process with PID 1234 to only use 25% of the CPU

Example: cpulimit {{[-p|--pid]}} {{1234}} {{[-l|--limit]}} {{25%}}

-e, --exeboolean

Limit an existing program by its executable name

Example: cpulimit {{[-e|--exe]}} {{program}} {{[-l|--limit]}} {{25}}

-b, --backgroundboolean

Launch a program, limit its CPU usage to 50% and run cpulimit in the background

Example: cpulimit {{[-l|--limit]}} {{50}} {{[-b|--background]}} -- {{program}}

-k, --killboolean

Kill its process if the program's CPU usage goes over 50%

Example: cpulimit {{[-l|--limit]}} 50 {{[-k|--kill]}} -- {{program}}

-m, --monitor-forksboolean

Throttle both it and its child processes so that none go about 25% CPU

Example: cpulimit {{[-l|--limit]}} {{25}} {{[-m|--monitor-forks]}} -- {{program}}

Limit an existing process with PID 1234 to only use 25% of the CPU

cpulimit [-p|--pid] 1234 [-l|--limit] 25%

Limit an existing program by its executable name

cpulimit [-e|--exe] program [-l|--limit] 25

Launch a given program and limit it to only use 50% of the CPU

cpulimit [-l|--limit] 50 -- program argument1 argument2 ...

Launch a program, limit its CPU usage to 50% and run cpulimit in the background

cpulimit [-l|--limit] 50 [-b|--background] -- program

Kill its process if the program's CPU usage goes over 50%

cpulimit [-l|--limit] 50 [-k|--kill] -- program

Throttle both it and its child processes so that none go about 25% CPU

cpulimit [-l|--limit] 25 [-m|--monitor-forks] -- program
