2.14) How do I ring the terminal bell during a shell script?

      The answer depends on your Unix version (or rather on the kind of
      "echo" program that is available on your machine).

      A BSD-like "echo" uses the "-n" option for suppressing the final
      newline and does not understand the octal \nnn notation.  Thus
      the command is

        echo -n '^G'

      where ^G means a _literal_ BEL-character (you can produce this in
      emacs using "Ctrl-Q Ctrl-G" and in vi using "Ctrl-V Ctrl-G").

      A SysV-like "echo" understands the \nnn notation and uses \c to
      suppress the final newline, so the answer is:

        echo '\007\c'
