Wouldn't that be because it's escaping the '.' for the shell but not grep?

So 'grep \\. /etc/passwd' will output only the lines that contain a '.'

Using [.] does indeed treat it as a literal.


Yes, '.' inside square brackets isn't a wildcard.

To keep it simple, why not surround your entire regex with single-quotes.
