  or slightly more effective:

  find . -type f |xargs grep char_string /dev/null

  it's also more poratable because -H is not as widely supported as the
rest of the above (of course, talking about debian, it is supported...)

  also note that 2> works only in sh-derived shells, in csh-derived
shells:

  (command > /dev/tty) >& /dev/null
