Is Linux a multiuser OS

Answer 1

Yes Linux does support the creation of multiple user accounts.

If you wish to learn to use the command line, these commands are how you create a new account along with a password.

1) useradd "new account name"

2) passwd "name of new account"

you will be prompted for a password then asked to retype it.

to delete a user type:

userdel "name of account"

to delete the account and all the accounts files type:

userdel -r "name of account"

All of the commands I've listed must be run by the root account.

Answer 2

yes it is. Linux is a multiuser OS.
