Check which groups you are in, and which are available:
|
|
|
|
```sh
|
|
groups
|
|
cat /etc/group
|
|
column -ts: /etc/group
|
|
grep $USER !$
|
|
```
|
|
|
|
Remove yourself from all groups, and add yourself back to only `mail`, `audio`, and your own group:
|
|
|
|
```sh
|
|
sudo usermod --groups mail,audio,$USER
|
|
```
|
|
|
|
Add yourself to the `docker` group, if there is one:
|
|
|
|
```sh
|
|
grep docker /etc/group
|
|
sudo usermod --append --groups docker $USER
|
|
```
|
|
|
|
Add yourself to the `games` group:
|
|
|
|
```sh
|
|
sudo usermod -aG games $USER
|
|
```
|
|
|
|
You are now legally permitted to play [games](shell/games.md).
|
|
|
|
The changes have not taken effect, so log into your own account again with `su`:
|
|
|
|
|
|
```sh
|
|
groups
|
|
grep audio /etc/group
|
|
|
|
sudo usermod -aG audio $USER
|
|
groups
|
|
grep audio /etc/group
|
|
|
|
su $USER
|
|
groups
|
|
grep audio /etc/group
|
|
```
