Obviously, the shells use their own internal echo and don't call /bin/echo. sh and dash give me $ echo -ne "\033" | od -x 0000000 6e2d 2065 0a1b 0000006 i.e. echo is actually echoing the switch "-ne", followed by a space, ESC and newline. In bash, I get tom@tom-desktop:~$ echo --version --version tom@tom-desktop:~$ /bin/echo --version echo (GNU coreutils) 7.4 Copyright © 2009 Free Software Foundation, Inc.

I'll be using /bin/echo now to make sure the same echo is used in bash and sh. -- To unsubscribe from this list: send the line "unsubscribe linux-msdos" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
