My earlier post about deleting the first N lines was answered by this one-liner site {below}. I wasn't including any redirection; doing so finally resolved the problem. Now I need to delete every line from the 19th or so to the last line. Question one, can anybody explain the following syntax? What do "P", "D" "ba" represent, in other words?
# delete the last 10 lines of a file sed -e :a -e '$d;N;2,10ba' -e 'P;D' # method 1 sed -n -e :a -e '1,10!{P;N;D;};N;ba' # method 2 Question two, can sed do its thing inline? thanks in advance, gary -- Gary Kline [EMAIL PROTECTED] www.thought.org Public Service Unix http://jottings.thought.org http://transfinite.thought.org _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
