Let us look at how to remove the error cpulimit: command not found. With the support of our Apache hosting support services at Bobcares we will now learn how to remove the error.

Error: cpulimit: command not found

The cpulimit command is a Linux utility for limiting a process’s CPU consumption.

This is important if you want to guarantee that a process does not spend too much CPU time, or if we want to reduce the impact of a CPU-intensive task on overall system performance.

Here’s an example of how to use the cpulimit command:

# cpulimit -p PID -l LIMIT

The CPU utilization of the process with the supplied PID will be limited to the set limit (expressed as a percentage of the CPU’s total capacity). For example, if we set a restriction of 50%, the process will be prohibited from using more than 50% of the CPU’s time.

It is crucial to remember that reducing a process’s CPU consumption may have an impact on its performance and lead it to take longer to finish its duties.

As a result, the cpulimit command should be used with caution and only when absolutely required.

If we get the following error when using the command cpulimit:

cpulimit: command not found

Depending on our distribution, we can try installing the following package:

Debianapt-get: install cpulimit
Ubuntuapt-get install cpulimit
Alpineapk add cpulimit
Arch Linux pacman -S cpulimit
Kali Linux apt-get install cpulimit
Fedora dnf install cpulimit
OS Xbrew install cpulimit

cpulimit Command Examples

Below given are some of the use cases of the command line:

1. Restrict an existing PID 1234 process to just using 25% of the CPU:

   # cpulimit --pid 1234 --limit 25%
2. Restrict an existing program to the name of its executable:

   # cpulimit --exe program --limit 25
3. Start a software while limiting its CPU use to 50%:

   # cpulimit --limit 50 -- program arg1 arg2 ...
4. Start a software while limiting its CPU use to 50%:

   # cpulimit --limit 50 --background -- program
5. If the program’s CPU consumption exceeds 50%, kill the process:

   # cpulimit --limit 50 --kill -- program
6. Reduce the CPU use of it and its descendant processes such that none exceed 25%:

   # cpulimit --limit 25 --monitor-forks -- program
