# Simple kernel module
Simple kernel module programmed for kernel version `6.8.0-51-generic`. This repository was created in order to understand how to program a kernel module, compile, load and remove it.
## Compilation process
Compile the module using make
```shell
$ make
```
Once compiled load it into the kernel
```shell
sudo insmod hello-1.ko
```
Now using the `lsmod` command you can see it, if you want to see the `Hello World` string you can use `sudo dmesg`.
```shell
$ sudo dmesg
...
[ 7659.352222] Hello, world 2
...
```
To remove the module from the kernel you can use `rmmod`.
```shell
$ sudo rmmod hello-1
```
