Problem with sed is that it has a set of advanced features that very few people ever work out how to use. Simple facts like the possibility of using another string delimiter probably get lost in the melee. The advanced features could probably be wripped out and I doubt if anyone would notice... -- Regards Cliff Sarginson The Netherlands [ This mail has been checked as virus-free ] To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-questions in the body of the message

If a zero-length extension is given, no backup will be saved. It is not recommended to give a zero-length extension when in-place editing files, as you risk corruption or partial content in situ ations where disk space is exhausted, etc. -- If you cc me or remove the list(s) completely I'll most likely ignore your message.see http://www.eyrie.org./~eagle/faqs/questions.html To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-questions in the body of the message

Unfortunately I deleted your other mail, asking how to remove lines
containing some text in a file, but this might be one of many
solutions:
# perl -e 'open(FD,file); while(FD) { if(!($_ =~ /texttolookfor/)) { print $_;
}} close(FD);' file.tmp
This has not been tested, so use it at your own risk. :-)
