This is not specific to Cygwin in any way, so it's kind of off-topic for
this mailing list.  I suggest you google for regular expression
tutorials, as this is the basis for how grep operates.

If it were me I would use grep -P "^\S+\s+yyyy" but there are numerous
ways to accomplish this and it would depend on the specifics of the data
that you're trying to match.
