handling parenthesis and quotes

[Adam]

Am using Emacs and Slime in Linux, and looked 
thru the Emacs and Elisp manuals, but so far 
haven't found how to do this trivial thing; 
to dispatch a grep line to a Lisp subprocess:- 

(shell "grep -i "(define " ~/mydir/myfile?.lisp") 

Have tried ' and \ and \: but ask how I should  
include " or ( in such a line.
