Search engines did not help much here. Any SED solution would be nice.
sed -e '/pattern1/{/pattern2/d;}' inputfile
will work. Also, there are options with awk/perl.
AWK: awk '!(/pattern1/ && /pattern2/)' inputfile
Perl: perl -ne 'next if (/pattern1/ && /pattern2/); print;' inputfile
With sed and perl, we have the added advantage of inplace editing.
With awk, only GNU awk has it (at least that's what I remember).
Thanks
