Grep - How to suppress the "Is a directory" line?

Question

When running

grep 'string' *

I'm getting the following messages:

grep: some-directory: Is a directory
grep: other-directory: Is a directory

How to suppress those messages?

Also, redirecting error messages to /dev/null. I.e. `grep 'string' * 2> /dev/null` – CPH Jul 23 '21 at 15:13
`grep -d skip 'string' *` – Jul 24 '21 at 05:21
