Well, "--" means "treat everything that follows as a filename / directory, not
a flag, even if it begins with a dash" so that wasn't really very relevant here
after all.
You started by using double quotes, in which special characters like "!" get
interpreted. ("!" is special to Bash, not to Grep.) Since you didn't want that,
using single quotes is the solution to suppress the special meaning.
You also weren't specifying what to search, hence stdin was being searched,
hence grep's warning that you asked for a recursive search (which is applicable
only to directories) but you didn't specify any directories.
