I want to make a perl script that will authenticate a user when he
logs in by askin him for his account name, if he enters it correct it
will allow him in, if not it will kill his shell ( Basically I put
this script to run in /etc/profile so it will run on any login, and
actually the user is already logged in, but if he enters a name NOT in
my array, it will kill his shell and kick him out... Should I usean
'awk' command in the script.. any suggestions ??? Thanks alot...

OK, but why? Didn't 'login' just do that for you?

why not just give them /dev/null as a shell? or lock their accounts?

for perl advice, you would be better off at comp.lang.perl.misc, but unless you
need to do something besides kick them out, letting them that far in is a bad
idea...you will need to trap signals and such to ensure they can't break out of
the script, and it is unnecessarily complex...and shelling out to yet another
program is just going to make it messier...

So once I log in - I can read /etc/profile and see what all the accounts in
the array are?
Huh?
