# cpulimit-daemon
A daemon to continuously limit the CPU utilization of one or more processes to a specific percentage.
Unlike other tools, cpulimit-daemon can also limit processes that did not exist at the time of
launching cpulimit-daemon by constantly monitoring running processes and applying limits on the fly.
# How to use
To use this script you have to download it from this repo.
## Requirements
Since this script relies on [cpulimit](https://github.com/opsengine/cpulimit), it has to be available on your system.
On Arch Linux it can be installed using
```shell
sudo pacman -S cpulimit
```
## Usage
```
>> ./cpulimit-daemon
Usage: cpulimit-daemon [-f] -e "myprocess.*-some -process -arguments" -p 100
```
## Parameters
| Name | Type | Description |
|------|---------|-------------|
| `-f` | Flag | Whether to apply the expression to the full command (including arguments) |
| `-e` | ERE | Expression to match processes with |
| `-p` | Integer | CPU usage percentage limit |
## Examples
```shell
sudo ./cpulimit-daemon -e chrome -p 50
```
