    I have personally been using it for about 4 maybe 5 years now. I started with redhat 9, and moved to fedora core 4, somewhere along the line became an ubuntu convert.

    I am by no means a linux expert, but I can also help answer questions.

    For those of you who don't know, linux is only the kernel (the brain) of your operating system, meaning any features and pretty eyecandy(compiz fusion) are uhh.. We'll call it "homebrew" almost everything for linux is "homebrew"

    which is why it is viewed as a better operating system by a lot of people

    In linux there is no C:\ drive instead you have / Which is called your root directory, drive letters actually don't exist in linux.
    instead, you have what are called mountpoints, most newer operating systems do all this for you, but back in the day you had to mount it yourself.
    it used to be everything was mounted in /mnt but newer linux distro's are putting things in /media (not sure when that change took place)

    you also have a home folder this is like documents and settings in windows XP

    your home folder has your name on it, and this is like my documents

    Linux is mostly 2 letter commands
    the 2 absolute most common commands are
    cd and ls

    you might recognize cd, and ls is actually dir

    if you ever see a command and you don't know what it is, type man "command

    like man ls

    although not as common as it used to be, you will sometimes see files that need to be compiled, and will come in a compressed tar.gz
    wikipedia has a good list of commands for dealing with basic linux stuff,

    also linux commands are CASE sensitive keep that in mind.

    ok I am out of ideas post questions and I will answer them.

    don't forget there is about 20 different commands usually for the same single command. I used to code Linux boot configs years back. I barely remember any of those commands anymore haha.

    One thing everyone should check out - UUID's for mounting partitions.

    Instead of using /dev/sda1 for your external hard drive you could use UUID=9294784382747 (the numerical string is unique to the partition on the drive.) This is so if you have more than one external device and you mount it with fstab it will have different mountpoints every time you switch the external drive. See, if you don't use UUID, Linux thinks that external HDD A is the same as external HDD B. If you use the UUID, Linux knows the difference

    It comes in handy when you want to mount two externals at once, etc.
