how to install kext from usb stick in terminal

Hey thanks alot for your help guys , these info's really help me out, i was having a hard time finding some console commands for terminal with google.

Do any of you know a site where you can learn more of these commands ?
i've come across some pages on google with lots of commands but with the little knowledge of terminal i have it's hard to use then without knowing what they mean

To install kext, driver for example your chipset controller or graphic card, you need some basic console commands. This is a basic, usual routine to install some kext.
Suppose that kext is in the root of your usb drive. If not, just point to the folder containing the kext by adding /~FolderName/ before ~DriverName.kext

Become 'su' first

sudo -s

You can list your Partitions/Volumes with

ls /Volumes

Copy kext:

cp -r /Volumes/USBPartitionName/~DriverName.kext /Volumes/~LeopardPartitionName/System/Library/Extensions

*Do the same for every kext you want to install.

Change permissions and ownership to new installed kext(s).

chmod -R 755 /Volumes/~LeopardPartitionName/System/Library/Extensions/Kextname.kext
chown -R root:wheel /Volumes/~LeopardPartitionName/System/Library/Extensions/Kextname.kext

*Do the same for every kext you installed.

Remove cache and rebuild:

rm -rf /Volumes/~LeopardPartitionName/System/Library/Extensions.mkext
kextcache -k /Volumes/~LeopardPartitionName/System/Library/Extensions

Reboot.

If your in Single User Mode by booting with -s you can mount your USB thumb drive like this.

Boot into Single User Mode without the USB thumb drive plugged in.

1. Allow for the modification of files by typing:

/sbin/mount -uw /

2. Make a directory in Volumes to mount to. We will call it "usbstick" by typing:

mkdir /Volumes/usbstick

3. Before we plug it in we need to make reference to what other drives we see in /dev by typing (You might want to write them down):

ls /dev/disk*

4. Now plug in the usb thumb drive, wait a second then look for a new addition by typing:

ls /dev/disk*

5. Now lets mount it. Lets say you there are two new additions disk4 & disk4s1. Type the following (replace msdos with hfs depending on how the usb thumb drive is formatted. If you use it on a PC too then its msdos):

mount -t msdos /dev/disk4s1 /Volumes/usbstick

Then you can access your usb thumb drive at /Volumes/usbstick

If you are getting a basic understanding of the commands that Milanca posted then you should be able to supliment them with your USB thumb drive's location.
