We have even fought hard to defend your privacy in legal cases; however, we've done it with almost no financial support -- paying out of pocket to continue providing the service. Due to the issues imposed on us by advertisers, we also stopped hosting most ads on the forums many years ago. We hope you appreciate our efforts.

1. To find out what shell you're using:
$echo $SHELL

2. To see what shells are available on your system,
$ls /usr/bin/*sh

3. To change your prompt to appear more like the DOS prompt
$PS1=">"
A C shell user would use the following command to change a prompt:
$set prompt="Mr. XYZ>"

4. To change the delete character (to remove the characters of a command entered), use the stty erase command
$stty erase [Del]
[Del[ refers to the physical act of pressing the Delete key.

5. If you make several errors and want to erase the entire line, type the @ character(shift 2). This presents you with a new prompt:
$lssset@
$
For Korn shell user, use the Esc key instead of the @ key to erase a line.

6. To change your password:
$passwd

7. To display one month calendar:
$cal
To see the calendar for an year, type
$cal 2007

8. To see who else is logged onto the system,
$who

9. To get more information about all users who have currently logged in, use the finger command:
$finger
To know about specific user,
$finger xyz

10. To display online-manual pages associated with UNIX commands use man command
$man ls
$man man

11. To reboot the system
$reboot
