macro to invoke shell command

[Peter Lee]

I'm having trouble writing a macro to perform a grep-find
command. Basically I just want to grep the current word in the
buffer. I would like to be use grep-find for this.

This doesnt work.

(defun grep-cur-word (&optional arg)
  "grep-find on the current word"
  (interactive "p")
  (grep-find (current-word)))

The defaults for my grep-find are:
find . -iregex ".*\.cpp\|.*\.c\|.*\.h\|.*\.idl\|.*\.rc\|.*\.tl[ih]"
-print0 | xargs -0 -e grep -n -i -e 

So normally I would M-x grep-find <ret>
and it would display:
find . -iregex ".*\.cpp\|.*\.c\|.*\.h\|.*\.idl\|.*\.rc\|.*\.tl[ih]"
-print0 | xargs -0 -e grep -n -i -e 

Then I just fill in the word at the end enclosed in quotes:
find . -iregex ".*\.cpp\|.*\.c\|.*\.h\|.*\.idl\|.*\.rc\|.*\.tl[ih]"
-print0 | xargs -0 -e grep -n -i -e "m_dwTicks"

My lisp is very weak and would appreciate any help. I just want to be
able to put cursor on word and hit a key to make the above happen.

Any ideas?

Thanks.
