you could do 10 commands on nothing more than variations on grep:
grep -r <string> ... as you mentioned above
grep -rw <string> ... must be separate word
grep -rwl <string> ... print only file name, which inspires
$ vi $(grep -rwl <string .)
that last one using command substitution to take the output of the
grep command, and make it the arguments to the vi command. i use that
last variation -- using grep to generate the arguments for another
command -- literally on a daily basis.
