Seek

• seek adjusts the current position of a filehandle

        use Fcntl ':seek';    # For SEEK_SET etc.

• Absolute position:

        seek FH, $position, SEEK_SET;

• Relative position:

        seek FH, $position, SEEK_CUR;

• Relative to the end of the file:

        seek FH, $position, SEEK_END;

• tell returns the current absolute position:

        my $position = tell FH;

        # read, write, and seek FH here ...

        seek FH, $position, SEEK_SET;

• This is guaranteed to put the handle back where it was at the time of the tell
