This is a tail -f and the log file is a dhcp log so it has A LOT of lines not only 10 :)

    Here's a live example for you:

    $ tail -f multtable.txt 0 9 18 27 36 45 54 63 72 81
    The code that generated that was:
    for ix in 0 1 2 3 4 5 6 7 8 9 do for iy in 0 1 2 3 4 5 6 7 8 9 do n=`expr ${ix} '*' ${iy}` echo $n >> multtable.txt done done
    That makes 100 lines. I do a "tail -f" and I see the last 10 lines all day long until someone writes to it. While I can't comment on the data set you are working with I can tell you about the behavior of most *nix commands.

    Should cpanminus be part of the standard Perl release?
