Hello. I have installed Zenwalk, but I have a problem (probably designed that way, but I don't like it

) :
A non-root user can't see programs that require root privileges (in terminal). For example, when I type
I get
Code:
bash: netpkg: command not found
. This goes for all commands that require root privileges, which is annoying

(can't see them, can't use auto-complete with them, etc)
In Fedora, I get an error message when I try to use a program that requires more privileges than I've got, but in Zenwalk, I don't even see those with sudo! I have to log in as root (or use su)... Any idea on why this is, and how to fix it?
Thank you in advance, and sorry if I misspelled something. My spell checker is broken too
