Hey,
It seems in don't have some commands that I've been asked to use in other threads to solve a problem such as modprobe, iwconfig and lsusb. There are probably others I don't have either.

When I try to use these, it says that the command is not found even though I do have man pages for them.

I tried using them as both a regular user and as the super user. I tried searching on this subject but all I get are threads that ask people to use these commands.

Any help would be appreciated, thanks.

By the way, I'm using Fedora Core 1.

The location of these utilities may not be in your path. I run Debian, but on my machine, modprobe is located at /sbin/modprobe. Use the find command to locate it on yours.
# find / -name modprobe
Then check your path to see if the folder is included. You should be logged in as root when you check this.
# echo $PATH

Thanks, that helped.

I'm not sure about the second part of your answer though. Is my path a group of folders that are searched for when a command is used? ie. if modprobe is typed, then it checks that group of folders for the command?

And if that's right, how do I add a folder to my path?

Thanks again for your help.

Yes, that's exactly it. To add /home/dubya/bin to your path type the following.
# PATH=$PATH:/home/dubya/bin
(where # is your command prompt) This is only temporary however. In order for the system to remember this, add the following line to ~/.profile
export PATH=$PATH:/home/dubya/bin
