    Can someone explain this one a little more.
    I did a quick look in programming perl and Advanced perl programming and did not see anything like this.

    Thanks
      Hi, sorry for the terse answer!
      Its the syntax for combining this
      open(FH, "<$file"); binmode(FH, ":crlf");

      The :crlf bit just tells perl to look for varients of line-ending sequences & turn them all into "\n".
      there is more info in the Cammel book.

      Update
      In the "open" documentation, Page 754 in the 3rd edition.

        Thanks, Must be time to retire my 2nd Ed. and get the 3rd.
        I also did a little more RTFM and found it in perlfunc.

        This may seem like a trivial thing to some but I always assume my input files are unix based therefore I fight this problem more often than I would like to admit.

        I've converted files using unix tools and converted lines in a sloppy way that always got the job done but seemed like more of a hack than anything. I really needed something quick (starting to sound like the usual case for me? Re: Don't go all PerlMonks on me -- leaving for a long weekend (AGAIN), in less than an hour (AGAIN)).

        This was so simply and worked with almost a simply cut/paste (I only changed the file handle). I was going to do sloppy programming (I was told to read documentation, but really wanted to test and troubleshoot if it threw an error) but this worked like a charm - clean and concise without the use of confusing regular expressions.

        Thank you so very much.
