Answer 1

try grep -wF

from man page:

 -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.



 -F, --fixed-strings
              Interpret  PATTERN as a list of fixed strings, separated by newlines, any
              of which is to be matched.  (-F is specified by POSIX.)
