But whats your end goal? What is it going to do at the end? -----Original Message----- From: Pat Rice [mailto:[EMAIL PROTECTED] Sent: 13 September 2007 14:16 To: Chas Owens Cc: beginners@perl.org Subject: Re: adding data to a file before it gets regexed
Thanks Chas for the reply what I'm trying to do is add the file name to the start of the string beign placed in the array, I havent used hashes so I'm not fiormlar with using hashes, but I am open to using them. The reasion I am trying to add the string to the line, is so that I can use it in a regex afterwards, so it will break out what file was assiated with the line, as I have a list of files that i am adding together. I'm using opendir to get a list of files, then opening the files using open, but I want to add the file to the string.
