There are two spaces here, where there ought to be only one.  I also
note that "\" and "|" are on the same key on my keyboard.  I'm
guessing you're accidentally typing "ps -ef |\ grep foo".  So bash is
trying to run a command called " grep", which doesn't exist.  I guess
the error message would be clearer if the command name were enclosed
in quotes.

If this is not the case, check the value of $PATH and the output of
"which grep" the next time this problem occurs.
