- 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://software.codidact.com/posts/288326 However, I simply put the files in `/tmp/` where they get automatically wiped at next system shutdown.
