hi monks

I'm trying to check if a file exists, and if it does, increment the name and create a new one.

So if the file 07141998.html exists, I want to create 07141998_1.html

(of course I need to check if _that_ exists first...)

Here's how I do it:

$name = ..... # whatever
if (-e $name) {
for (my $i = 1; -e ($name = $name."_$i"); $i++) {}; # get unique name
}

I took the above code from a site...so i want to know how does the "e" works in the above code....can anybody help me understand it

Thanks
