Looking for some basic info on file locking and when to use it. From what I understand, file locking prevents a file from being accessed by two or more processes at the same time.

I'm a bit ignorant on processes so I need some clarification. Let's say I've got a .cgi file on my server that asks for a password and checks it against the password in a text file. The password file is shared by a couple of different scripts.

So is file locking needed in this situation? Or is it impossible for the password file to be accessed simultaneouly because only one .cgi script can be run at a time? Or am I totally f***** up on all this?

$PM = "Perl Monk's";
$MCF = "Most Clueless Friar";
$nysus = $PM . $MCF;
