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. :-) Best regards, Paul To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
