echo

SYNTAX
      
        echo [-n] [string ...]
  
  Options
               -n     Do not print the trailing newline character.	 This may also be
	   
              achieved by appending `\c' to the end of the string, as is done by
	   
            iBCS2 compatible systems.
To produce a default beep:
echo '^G^G^G^G'
where you get the literal ^G characters (which represent ASCII 7, the BEL character) by typing "ctrl-v ctrl-g".
The echo utility exits 0 on success, and >0 if an error occurs.
