I am new to perl. I had a look at ur node, what does '-f' stand for in the statement
unlink $temp_file_name if -f $temp_file_name;
and what is '$|' variable?

    -f is a file test operator used to see if a file is plain text. In my code, I was just deleting the file if it existed, and probably should have used -e. More information on file test operators can be found here.

    As far as $|++, this stops the buffering of the output. $|=1 is cleaner in this case, so I've updated my old node. For more info on $|++ and $|=1, here are some interesting, relevant nodes.
