Problem with character class using grep on Windows

I'm trying to use grep on Windows to search all files in the current directory for the word foo followed by any white space.

I tried:

grep foo\s *

But it doesn't work. It matches foos though. I was under the impression that \s should match a white space. Indeed it does in other regular expression testers.

I also tried grep foo\\s * grep "foo\s" * and countless other attempts.

What am I missing?

I'm using GNU grep 2.5.4 on Windows 10 in cmd.exe

It seems there is a bug with the handling of \s in grep up to version 2.5 grep regex whitespace behavior

You have several alternatives to it

grep "foo[ \t] *
grep "foo[[:space:]]" *

or if you dont care about tabulation

grep "foo " *
