Works *absolutely* fine -- ie the same as in a dtterm (no emacs).

(of course, no "more", etc, but grep, find, etc all work
      exactly as expected.  Likewise pushd, popd, dirs, etc.
    (Although from time to time it gets confused, at which

M-x locate, M-x grep, M-x cd etc. 
Huh?

About M-x grep, I find it very useful to use normal
   grep/egrep/etc, *with -n*, and on *at least 2 files*
    (eg if just one to be grepped, then append /dev/null to
      get to the 2-or-more-files -- so as to get file-names
      at the left of the grep-output)
   and then, if desired, hack that file to remove lines,
     add marks to certain lines, etc,
   and THEN do M-x grep, and change the offered args to
    "`cat mygrep.out`"

I don't understand, so: Please expain, ie show examples where necessary.
