RTFM:
        echo [-neE] [arg ...]
               Output the args, separated by spaces,  followed  by  a  
newline.
               The return status is always 0.  If -n is specified, the 
trailing
               newline is suppressed.  If the -e option is  given,  
interpreta-
               tion  of  the following backslash-escaped characters is 
enabled.
               The -E option disables the interpretation of these 
escape  char-
               acters,  even  on systems where they are interpreted by 
default.
               The xpg_echo shell option may be used to  dynamically  
determine
               whether  or not echo expands these escape characters by 
default.
               echo does not interpret -- to mean the  end  of  
options.   echo
               interprets the following escape sequences:
               \a     alert (bell)
               \b     backspace
               \c     suppress trailing newline
               \e     an escape character
               \f     form feed
               \n     new line
               \r     carriage return
               \t     horizontal tab
               \v     vertical tab
               \\     backslash
               \0nnn  the  eight-bit  character  whose value is the 
octal value
                      nnn (zero to three octal digits)
               \xHH   the eight-bit character whose value  is  the  
hexadecimal
                      value HH (one or two hex digits)
