what if one wants the output to be a list of file names, such as what you get
when using grep -l.

when using grep -l.

sorry the previous solution is wrong. it just proves one thing:
for every complex problem there is a solution that is simple,

here's the correct one, hopefully
grep -l aaa `grep -l bbb files-to-grep`
