Change root password

Q. How do I change the root password on a linux ( unix ) operating system ?

R. What you need to do in order to change the root account password on a linux or unix machine is:

- open a terminal an login as root ( if the system permits loging in as root )

or

- open a terminal, login with your account and type “su” to become root.

Enter the ( old ) root password to login

then type “passwd” and it will prompt you for a new password.

root@ibm:/# passwd

Changing password for root
Enter the new password (minimum of 5, maximum of 127 characters)
Please use a combination of upper and lower case letters and numbers.

New password: **********
Re-enter new password: **********

Password changed.

This should be all.

P.S. The password should be rather complex, containing numbers and letters. However try to pic one that you will remember easily, but not known by everybody.
