## 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)`
|
