Highlight a region, try to filter it with "grep xzy" via menu [Tools,
Shell Command on region] results in output in the minibuffer ok!
Trying this with M-| and nothing (useful) happens?

For what it's worth, I can't reproduce this.  Latest trunk,
x86_64-unknown-linux-gnu:

emacs -Q
C-SPC
M-<
M-| grep th RET

The grepped lines are shown.

Please provide a more precise recipe.

Thanks Chong for the response,

the reason for my bugreport was at the first look, a confusion about 
"bar" | and "brokenbar" ¦ which i didn't recognized until then.
My german keybord shows an brokenbar but emits a bar. I think its ok so far.

$ xmodmap -pke | grep bar # gives
keycode 94 = less greater less greater bar brokenbar bar

To create the keycord M-| i have to hold ALT (means Meta) hold AltGr to 
get the bar on german keycap <>| and even press <>| .
Examining this keycord with C-h k gives a reaction as if i had pressed 
nothing.

Typing a | in an ordinary buffer or on a linux-console works here. ???

With the help of xev I found that the keycord M-| emits nothing (in my 
configuration) so it may be no emacs problem.

I have exactly the same problem (German keyboard, Debian Wheezy).  I
don't think it's Emacs related (because of the xev behavior you see).

Some time ago, I couldn't type C-M-~.  Now, it suddenly works (?)
without any intervention.  Instead, M-| doesn't work.  Quite
mysterious.

At least, ESC |  works as a workaround for M-|.

That's because most keyboards can't process these three keys together
(lookup keyboard ghosting).  You need to use the ESC prefix instead of
the meta key.  If M-~ also doesn't work, then there might be a problem
with your X configuration and the mapping of the "Alt Gr" key, but I
think your problem is simply ghosting.  In any case, Emacs can't do
anything about it, it simply never got the keypress you think it should
be getting (most likely it'll see ALT_L and SHIFT_L3 pressed and
released, which means nothing to do).


Regards,
Achim.

I have updated etc/PROBLEMS with this information.  Thank you.
