# cpulimit
> A tool to throttle the CPU usage of other processes.
> More information: <http://cpulimit.sourceforge.net/>.
- Limit an existing process with PID 1234 to only use 25% of the CPU:
`cpulimit --pid {{1234}} --limit {{25%}}`
- Limit an existing program by its executable name:
`cpulimit --exe {{program}} --limit {{25}}`
- Launch a given program and limit it to only use 50% of the CPU:
`cpulimit --limit {{50}} -- {{program argument1 argument2 ...}}`
- Launch a program, limit its CPU usage to 50% and run cpulimit in the background:
`cpulimit --limit {{50}} --background -- {{program}}`
- Kill its process if the program's CPU usage goes over 50%:
`cpulimit --limit 50 --kill -- {{program}}`
- Throttle both it and its child processes so that none go about 25% CPU:
`cpulimit --limit {{25}} --monitor-forks -- {{program}}`
