## Users
Check users by looking at `/etc/passwd`
### Add users
Basic usage:
`# useradd -m (user)`
Important options:
```
login name -> by default
group -> -G //separate multiple by commas: group1,group2
with home dir -> -m
shell -> -s
full name -> -c
```
Example more complicated usage:
`# useradd -m -c "Bruno Huber" -s /bin/bash -G buchhaltung,sudo bruhub`
### Add user to groups
Add user to more groups:
`# usermod -a -G (group1),(group2) (user)`
Alternative command:
`# gpasswd -a (user) (group)`
### Remove user from group
`# gpasswd -d (user) (group)`
## Groups
Check a user's groups with `id (user)`
### Create group
`# groupadd (group)`
### Rename group
`# groupmod -n (new_group) (old_group)`
### Delete group
`# groupdel (group)`
