If basic Solaris^TM commands do not work as expected on your OpenSolaris^TM system, it might be because /usr/gnu/bin path precedes /usr/bin path in your command path. For example:

% echo $PATH
/usr/gnu/bin:/usr/bin:/usr/X11/bin:/usr/sbin:/sbin

To perform the tasks in this guide, you might need to identify the correct command, for example: /usr/bin/chmod or /usr/sbin/zfs.
