QNX is a POSIX OS, and is basically a very robust OS for appliances and such. Basically it runs on an ~8kb microkernel that is modular and 32bit. The microkernel is fabulous in that it deals with only abt 14 system calls and the 4 main functions - process scheduling, interprocess & network comms, and interrupts. To top it off QNX is a realtime OS. The difference between QNX and UNIX is very marginal in feel, in fact there's an X server for QNX floating around. Its however very Windoze friendly as well, as it supports ELF filesystems like CIFS, NFS...

My suggestion to learn QNX is to selectively learn the specific tools that QNX natively offers. For example check out: http://staff.qnx.com/~docs/comline.html
This of course is to add on to basic *NIX syntax that you have to learn. Most of the shells like the Bash2 etc are in fact ported to QNX as well.
