All of the suggested solutions are great, but ... If a file is too large to slurp in to memory, use mmap. It's perfect for the task and allows for the most natural solution. There are at least two mmap modules on CPAN. Of course, since I was not at the meeting, this may well have been discussed and I could be a day late! ;) -Gyepi _______________________________________________ Boston-pm mailing list [EMAIL PROTECTED] http://mail.pm.org/mailman/listinfo/boston-pm
