System Bootup:
If you have a computer which has UNIX operating system installed on it, then you simply need to turn on its power to make it live. As soon as you turn on the power,
system starts booting up and finally it prompts you to log into the system, which is an activity to log into the system and use it for your day to day activities.
Login Unix
When you first connect to a UNIX system, you usually see a prompt such as the following:-
login: |
To log in
- Have your userid (user identification) and password ready. Contact your system administrator if you don't have these yet.
- Type your userid at the login prompt, then press ENTER. Your userid is case-sensitive, so be sure you type it exactly as your system administrator instructed.
- Type your password at the password prompt, then press ENTER. Your password is also case-sensitive.
- If you provided correct userid and password then you would be allowed to enter into the system. Read the information and messages that come up on the screen something as below.

You would be provided with a command prompt ( sometime called $ prompt ) where you would type your all the commands. For example to check calendar you need to type cal command as follows:-

Change Password
All Unix systems require passwords to help ensure that your files and data remain your own and that the system itself is secure from hackers and crackers. Here are the steps to change your password:-
To start, type passwd at command prompt as shown below.
Enter your old password the one you're currently using.
Type in your new password. Always keep your password complex enough so that nobody can guess it. But make sure, you remember it.
You would need to verify the password by typing it again.
$ passwd
