To reassure yourself, run: 

C-x C-f ~/.emacs.d/init.el

If it opens your config file, you're good. If not, you should move your config 
into that location.

It looks like the command grep is not in your path. 

To ensure that it is, open the terminal where you usually run grep from and 
type: 

which grep 

Note the path (if grep is installed).

Then in Emacs: 

M-x eshell RET
which grep RET
echo $PATH RET

Check if grep is found in Eshell's path. If it isn't, you should add it.

Hope it helps
