Writing A Shell Script

Your assignment is to write a simple shell script called whereami. When invoked, this script will print out the user name of the current user, the name of the current machine, the full path name of the current working directory, the current time, and a listing of the contents of the current directory. Output from whereami should follow this example:

Your are         : edwards
You are on       : bohica.cs.vt.edu
Current directory: /home/edwards
The time is      : Sun Mar 30 20:18:00 EST 1997
Current directory contents:
1206-old/       bin/            invd2.dat       skel/           working/
A5.html         configs/        invd3.dat       sum3/
Bugs.txt        gnuemacs-lib/   invd4.dat       tools
Mail/           invd1.dat       nsmail/         whereami*

Remember that your shell script must start with a proper "bang line":

    #!/bin/csh -f
