Once you've logged in

After you've logged in, the system automatically runs the /home/username/.profile script.

This script lets you customize your working environment without affecting other users. For more information, see Configuring Your Environment.

To change your password:

Use the passwd command. This utility prompts you for your current and new passwords; see Managing your own account in Managing User Accounts.

To log in as a different user:

Enter login at the command prompt, and then enter the user's name and password.

Note: The su (switch user ID) utility also lets you run as another user, but temporarily. It doesn't run the user's profiles or significantly modify the environment. For more information, see the Utilities Reference.

To determine your current user name:

Use the id command.
