what are shell commands in qnx 6.3

I am newer to qnx 6.3 and wonder which document I can find these shell commands.

By the way, I am starting to develop device driver for intel-based 82527 CAN controller. Does someone know some sample code or some template I can follow?

Any suggestion is very appreciated.

The builtin shell commands are described in the entry for ksh in the Utilities Reference. This book also describes the various utilities, managers, and configuration files. If you’re new to QNX Neutrino, you might want to start with the Neutrino User’s Guide. You can find these books in the installed documentation (in $QNX_TARGET/usr/help/product), or on the QNX website.
