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
