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?

Between-lines relations are not easy to look for with grep, which is a line filter. You could use a regex that spans lines, but I find this annoying because of all the flags you have to set.
Grep has a switch for printing the filenames instead of matching lines. You can put each in a file. Once you have both files, you can use comm to do the union.
grep -r . -e 'foo' > foo.txt
grep -r . -e 'bar' > bar.txt
comm foo.txt bar.txt -12
If you don't want the temp files, you can use the command inline: https://linux.codidact.com/posts/288328/288329#answer-288329 However, I simply put the files in /tmp/ where they get automatically wiped at next system shutdown.
