have you tried using Tie::File it works great for me when reading and writing to files. Here is what I came up with:
#!perl use strict; use warnings; use Tie::File; my @log; my @archive; tie @log, 'Tie::File', "C:/WINDOWS/U.S. Robotics 56K Voice INT PnP.log +"; tie @archive, 'Tie::File', "H:/ppp_stats.log"; push @archive, @log; $#log = 0; pop @log; #otherwise the first line of the file #gets left there, untie @log; untie @archive;
I did acouple of test runs on small files and it worked for me, but you might want to run some test before using it as working code. Feel free to make any edits. I make no promise that this will work for you, but it worked when I ran it.

Update: I didn't put the use diagnostic in my code, I'm not sure what that does, I've never seen it before.

Update: as nothingmuch pointed out to me instead of finding the length of @log and subtracting that from $#log, I can just set $#log to 0, much easier :)

Update: now it won't leave the blank line in the log file, not sure if thats the best way to do it, but it works

to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
