hehe yeah the license agreement. In the Linux world that's basically, "here's the stuff, do what you like with it". There's nothing hidden about it. Almost everything is under the GPL or GPL2 license (some under the Apache license), not a difference license for each and every little thing. Since all you need to remember is to credit the source, you're free to give it away as is, modified or any combination thereof so long as you make the source code freely available, just don't try to sell stuff you got for free or claim it's your work when it isn't. Any software that has proprietary licenses, like the vNvidia or AMD graphics drives, make you scroll through the license just the same. The difference is that there's no need for you you to do that for EVERY piece of software. In some cases in Linux Land, there IS NO LICENSE AGREEMENT. The software is free for you to do with as you please and not covered by ANY license.
As for "most people", when Windows hit the market "most people" using computers were comfortable and familiar with the command line. The GUI took a long time for people to accept it. You just think the gui is easier because you're accustomed to seeing pretty pictures rather than using commands. Once you change how you think (remember nothing can be "better" if it's not DIFFERENT) and think about commands rather than clicking icons, you can do more and faster. Even Windows sys admins use the command line (and shell scripts) for that reason. "Most people" don't even realize they have a choice of what operating system they run let alone begin to grasp just how flexible the alternatives really are.
As for install options, classic Linux and Unix software installs consist of extracting a folder into your folder of choice (usually /home/<username>/<folder> or /usr/opt/<folder>) and just running the thing. No registry, no installer just unpack it (zip etc) and run it, which is how the BOINC installer from Berkley runs.
Shoota, take notes:
sudo dpkg -i <package>.deb
To remove the package simply change the -i switch to -r (for "remove")
If you don't want to type out the whole thing just use the * wildcard ie:
sudo dpkg -i package*.deb
and it will install every .deb package in the current directory that starts with "package".
let me decode that for you:
sudo ~ "super user do"
dpkg "debian package" package management utility
-i ~ "install"
Those files aren't self extracting and it was a mistake for you to assume they were. They are an ordered archive file with some additional information added that allows the package management utilities to put everything where it's supposed to be as well as keep records so that it can all be removed automatically.
Not being able to install anything anytime isn't a fault with the OS, it's a feature that Windows is trying to emulate with it's UAC. User level security, or more specifically the lack of it, has been a massive security issue for Windows since the beginning.
