The problem most probably is caused by your command shell
(COMMAND.COM, I assume) seeing the | character and deciding that you
want to pipe from one command to another.  You'll have to use *double*
quotes to avoid that interpretation, in command.com:

        egrep "a|b" myfile.txt

Single quotes don't mean a thing to command.com.
