# User Management Basic Commands
|
||
|
|
There are several commands that are crucial when managing users in Linux. Here are some of the most important ones:
|
||
|
|
|
||
|
|
1. `useradd`: This command is used to create a new user. For example: `useradd username`
|
||
|
|
|
||
|
|
2. `usermod`: This command modifies the properties of an existing user. For example, to add a user to a group: `usermod -aG groupname username`
|
||
|
|
|
||
|
|
3. `userdel`: This command deletes a user. For example: `userdel username`. Be careful with this command, it should be used with caution.
|
||
|
|
|
||
|
|
4. `passwd`: This command is used to change the user's password. For example, to change the password for a user: `passwd username`
|
||
|
|
|
||
|
|
5. `su`: This command is used to switch the current user to another user. For example, to switch to a user named "username", you would type: `su username`
|
||
|
|
|
||
|
|
6. `sudo`: This command is used to run commands with administrative privileges. For example: `sudo command`. It's equivalent to saying "run this command as the superuser".
|
||
|
|
|
||
|
|
7. `chown`: This command is used to change the owner of a file or directory. For example: `chown username filename`
|
||
|
|
|
||
|
|
8. `chgrp`: This command is used to change the group of a file or directory. For example: `chgrp groupname filename`
|
||
|
|
|
||
|
|
9. `groups`: This command is used to display the groups a user is a part of. For example: `groups username`
|
||
|
|
|
||
|
|
10. `id`: This command is used to display the user ID and group ID of a user. For example: `id username`
|
||
|
|
|
||
|
|
11. `whoami`: This command is used to display the current logged in user. Just type: `whoami`
|
||
|
|
|
||
|
|
12. `adduser`: This command is used to add a user (more user friendly than `useradd`). For example: `adduser username`
|
||
|
|
|
||
|
|
13. `addgroup`: This command is used to add a group. For example: `addgroup groupname`
|
||
|
|
|
||
|
|
14. `deluser`: This command is used to remove a user. For example: `deluser username`
|
||
|
|
|
||
|
|
15. `delgroup`: This command is used to remove a group. For example: `delgroup groupname`
|
||
|
|
|
||
|
|
Remember, the manual (`man`) pages are your best friend when learning about commands in Linux. You can access the man page for any command by typing `man` followed by the command name. For example, `man useradd` will show you the man page for the `useradd` command.
