Displaying extended ASCII characters in output of octal dump as hexadecimal
When I run octal dump (od) I notice that extended ASCII characters are displayed incorrectly as ordinary characters. For example, the extended characters 191, 196, and 218 are displayed as '?' , 'D' and 'Z' respectively. I thought od was 'anding' the each character with 127, but I've been informed that this because my shell/terminal is not configured to display non-ASCII characters.

Cygwin commands in the Windows command line
Hi - I've noticed for sometime that Cygwin commands such as "ps" and "ls" (now) work in the Windows command line (cmd), and I'm not sure if its because something extra I installed on/did to my machine. (In fact, the command "pwd", when run in the cmd, shows a Cygwin path like /cygdrive/c/Documents and Settings/my_name.) Is this as a result of tighter integration of Cygwin with cmd?

Re: Creating superuser (root) in Cygwin
You cannot just create a superuser in cygwin because cygwin is a translation layer for UNIX applications. Cygwin is not actual UNIX and there are limitations. Basically cygwin is using the host machine's security model rather than unix's own native security model and porting is not straight forward for some applications. It is even worse when it comes to WIndows 9x than with Windows NT where as 9x has no security model of its own (that I am aware about). The passwd and group files are there for compatibility and allows some applications to work. At least that is my understanding. Thanks Robert.
