Whoah.

As already said above...unless you are doing things which you don't mention in your post (trying to get around some obscure quotas etc) you *don't* want to be doing what you are trying to do.

There shouldn't be a problem if ten people are running their own copy of 'main.pl'. Or if there are (due to access to shared resources or whatever) then simply renaming the file is unlikely to get around the problem. If it does, (perhaps due to a locking file based on the name of the script created when the script is run) it is probably better to find out why and remove that limitation in the script.

Remember - duplicating code == bad. If you find a bug in your script or otherwise improve/change it you have to remember to change every copy of your script. This is the main reason why library code and modules are good. (Note to viewers: the reason for using CGI.pm (or other library module) is not primarily to avoid you writing code, it is to get code that has been tested by lots of people and so is likely to be correct/not insecure.)
