UPDATE!!!!

I thank you all! I finally broke my self of those horrible habits and have found the wonderfull miracles of the FH, mkdir calls etc... I'm no longer using system()!

Hello dear monks. I am currently working on creating a small Bulletin Board System with simple implimentations such as a Bulletin Board, IM, and the abbility to run the lynx browser. Am am doing this all in PERL and BASH. Untill now everything was going just fine. I have this code to read the current chat which resides in a txt file called chatlog.txt

#!/usr/bin/perl

system("clear");

$on = "true";
while ($on = "true") {
    system("clear");
    system("cat chatlog.txt");
    system("sleep 3");
    }

This works just as expected! BUT, then I have this piece of code!

#!/usr/bin/perl

system("clear");

$on = "true";
while ($on = "true") {
system("read $in");
system("echo "$in" >> chatlog.txt);
}

Now this should work just fine. When I run this kind of thin in bash directly throught the terminal it does, but when I run it from the file it dosen't echo the $in to the txt file. Please try and see for your selves... If somebody could solve this I'd apreciate it.
