Find all files which contain specific text and print these file names to the console

If a file contains either word “some” or word “text” then print its name

# q = quiet; that means that grep will exit with status "0" (success)

# if a file contains either word "some" or word "text"

find . -type f -exec bash -c "grep -q -e some -e text {} && echo {}" \;

let a = 10, b = 20;

[a, b] = [b, a];
