Newbie Student Need Help!

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!

lchage(1)						      General Commands Manual							 lchage(1)

NAME
lchage - Display or change user password policy SYNOPSIS
lchage [OPTION]... user DESCRIPTION
Displays or allows changing password policy of user. OPTIONS
-d, --date=days Set the date of last password change to days after Jan 1 1970. Set days to -1 to disable password expiration (i.e. to ignore --mindays, and --maxdays and related settings). Set days to 0 to enforce password change on next login. (This also disables password expiration until the password is changed.) -E, --expire=days Set the account expiration date to days after Jan 1 1970. Set days to -1 to disable account expiration. -i, --interactive Ask all questions when connecting to the user database, even if default answers are set up in libuser configuration. -I, --inactive=days Disable the account after days after password expires (after the user is required to change the password). Set days to -1 to keep the account enabled indefinitely after password expiration. -l, --list Only list current user's policy and make no changes. -m, --mindays=days Require at least days days between password changes. Set days to 0 or -1 to disable this requirement. If this value is larger than the value set by --maxdays, the user cannot change the pasword. -M, --maxdays=days Require changing the password after days since last password change. Set days to -1 to disable password expiration. -W, --warndays=days Start warning the user days before password expires (before the user is required to change the password). Set days to 0 or -1 to disable the warning. EXIT STATUS
The exit status is 0 on success, nonzero on error. NOTES
Note that "account expiration" (set by --expire) is distinct from "password expiration" (set by --maxdays). Account expiration happens on a fixed date regardless of password changes. Password expiration is relative to the date of last password change. libuser Nov 8 2012 lchage(1)
