I am frustrated (HELP)
 

HELP!!
I'm trying to install a driver for the PCI wireless adaptor but failed many times.
here is how I did it. log-in as root, download the driver via download manager to /tmp directory. and then the manufactory website says to use "tar zxvf" command to unpack the driver file (don't unpack the driver files to root directory), ok so I typed "tar zxvf"in the terminal...doesn't work and I also try "tar zxvf FILE NAME"....doesn't work either...><...

well, do I need to switch from ROOT to /tmp in the terminal since I save the file to /tmp.....anyways, I need some helps SOS..

cd /tmp
tar -zxvf filename.tar.gz

Thanks...I should have thought of "cd"....
what kind of program/file should I save to /usr instead of /tmp

personal choice... i don't save anything to /usr

--but nor do i use /tmp

I will download to my ~, and if i plan to install, move to /usr/src for decompression/compilation/installation
