Linux - Create and Delete User + Change Permission

As a root/admin user, manage other user account and accessing permision.

Create a new user account

• Add a new user called test

$ sudo adduser test

• Type and retype password of the new user

• Force the new user to change her password after first logon (expire the current one)

$ sudo passwd -e test

Delete an existing user account

• Use the userdel command as follows:

$ sudo userdel test

• To remove home directory and mail spool too, enter:

$ sudo userdel -r test

Create Working Directory for New User (in /mnt)

Remark: There are two harddisks mounted to the department sever. We need divide the users into different disks and balance the space usage. Take /mnt/disk1 as example,

• Create new directory, named by user

$ sudo mkdir /mnt/disk1/test

• Change the ownership of the directory

$ sudo chown -R [username] [user directory]

$ sudo chown -R test /mnt/disk1/test

Change Permission

• Only the owner of the directory can read/write/excute it

$ sudo chmod -R 700 /mnt/disk1/test
