Shell Programming and Scripting

Is there anyone here that can help me with my unix assignment? I've been working on it for 3 days now. It is regarding writing a script. I've got a few questions that I need some answers. Please someone who are willing to help add me to their msn messenger: ****************

In one part of the assignment, I have to create a script called "validUser.sh". So if I was to run the script, I would type "validUser.sh username" from the shell, and the script is supposed to take the username and search for that in a database. My problem is I don't know how to take the 2nd option: validUSer.sh --> username <--
and search for it! It will only work if I run the script from the shell, then type the username.

ex.
$ validUser.sh
username

Won't work likt this:

$ validUser.sh username


How do I make the script so that I can run it from the shell like so: "validUser.sh username" .. and it will automatically search for the username?

I got more other questions.. but it's too complicating to write them all here. So please someone add me to msn.


Thanks!
