help with Linux commends needed

[Joseph Tandl]

I am "exploring" Linux and, because I am a complete greenhorn (with Linux and programming of any kind), I need to find documentation for all simple line commands that are needed to open, unzip, move, compile, save, etc, files in text mode. 

I am working with Red Hat 7.3, for which I had to download nVidia kernel, GLX and driver rpm, tar and gz type files in an attempt to get X windows to work. (The files are now in a partition shared between Win2000 and Linux on a PC that has an nForce420D chipset in its MSI K7N420Pro socket A motherboard. I have to get them into Linux and do with them whatever it takes to make them work.)

Can you point me to website(s) or person(s) with such knowledge?
