Looking at the man page for everything in /bin that matches the pattern
*.exe find the following that may be of interest.  Testing to see if these
actually work is left as an exercise for the OP.  :-)

pcregrep - a grep with Perl-compatible regular expressions.

grep, egrep, fgrep - print lines matching a pattern
 -w, --word-regexp
        Select only those lines containing matches that form whole
        words.  The test is that the matching substring must either be
        at the beginning of the line, or preceded by a non-word
        constituent character.  Similarly, it must be either at the end
        of the line or followed by a non-word constituent character.
        Word-constituent characters are letters, digits, and the
        underscore.
