in reply to How can I grab the last 2 lines of a file?

Normally, I'd suggest a pure Perl solution, such as the one AppleFritter suggested but in this case I'll suggest a mixed perl/shell solution that needs only 1 line of code.

my ($id, $name) = split {$/}, `tail -2 /path/to/file`;

    Clever solution ++

    ... if you're on a *NIX system, or on a system that otherwise has the tail executable installed somewhere in its PATH.

      Hi Monks!
      I came across this post and it seems very helpful to a snippet of code i am trying to put together...Actually, I am interested in exactly the same thing as requested here, with the exception of removing these N (e.g. 2) lines from the file...It this possible?

        This it! See truncate.

        But you need to know the start of the lines to be dropped (see tell ), so the same techniques apply like described in this thread.

        edit

        Of course much easier if the length of the lines to be skipped are already known.

        Cheers Rolf
