grep AND search for multiple words in files
I have text (xml actually) files. Some files contain 'foo', some contain 'bar', some contain neither and some contain both. It's the both I'm interested in.
How do I do an AND search on words in files in folders (recursively) with grep? I'm using git bash in windows, so either a cygwin or win10 solution works.
I had thought pipeing to grep would work as it seems to be the solution for multiple text on a line, but I don't think I've changed it to work for files correctly.
This is what I tried:
$ grep -rnw . -e 'foo' | grep -e 'bar'
Can someone tell me how to fix my grep call?

To find lines which contain both:
find . -type f -exec awk '/foo/ && /bar/' {} +
(Maybe add { print FILENAME ":" FNR ":" $0 } before the closing quote if you want the filename and the line number.)
To find files which contain both;
find . -type f -exec awk 'FNR==1 { foo=0; bar=0 }
foo && bar { print FILENAME; nextfile }
/foo/ { ++foo }
/bar/ { ++bar }' {} +
