Maybe awk could help here
awk '/pattern1/ {next} /pattern2/ {print FILENAME}' somefile.txt
to translate this: if pattern1 is found, we jump to find the 'next' pattern=
in
the file. If that is found as well, we print the FILENAME.
You can use this on all files using a bit of shell kungfu:
for f in *; do awk '<whatever here>' "$f"; done
