comment bash's builtin time accepts %E - what's going on?
Indeed! Though I'm pretty sure something is wrong (with the blame falling on the man page maintainers) if we really have to go to the source code to see the explanation for this.

comment Why do I have to make my own drivers?
fair point - I should say, if there isn't a package available that contains the driver, then you have to download it manually. If the manufacturer, or whoever provides the driver, has a prebuilt binary package, you use that; if they provide the source code, then you need to compile it. That much is OS-independent. However it's conventional to provide only binary packages for Windows and Mac, whereas it's more conventional to provide source code for Linux, probably due to the wide variety of configurations Linux systems can have.

comment Why do I have to make my own drivers?
You install drivers using apt-get the same way you'd install any other program. You just need to figure out the package name that corresponds to the driver you need, and make sure it's in one of your repositories. If there isn't a package available that contains the driver, then you probably need to compile it from the source code, but that's no different from how things work on any other OS.

*NIX doesn't require you to compile your own drivers. In Linux distribution in which packages aren't compiled from source (most prominently Ubuntu), you download precompiled drivers and programs using the package manager.

comment How do you remember command options?
I fully agree with this answer, though I think it's worth emphasizing that it is normal to have the few most common options to common programs memorized, just because you use them so often. Like rm -i -f -r, ln -s, df -s -h, cp -r -i, ls -l -h -a, etc. (the list varies from person to person).

comment Can GPL software be bought by a company and still released as GPL?
One thing that might be worth clarifying: that the GPL only requires you to distribute software under the GPL if you are going to distribute it at all, but it doesn't require you to distribute it, period. I've seen people get confused by that.

comment How to make user passwords shown as a clear text in Linux?
@user78050 because the root user has no reason to know the passwords of other users, and it would be a major security risk to allow them to do so.

@vinc17 huh, I thought I did a test that showed otherwise but you're right. I've changed the answer.

comment How can I tell when a file was compressed?
@Networker I don't believe so, because this is asking for when (not whether) the file was compressed.

comment Flash Player on Linux
It is possible to take the Flash plugin from Chrome and use it in Chromium. I don't know the exact details of how, but Gentoo at least packages it in this way, so you can install a package containing the Flash and PDF plugins for Chromium.

comment How can I view a reference or cheat sheet of the basic bash syntax, in the linux terminal?
@SamuelLampa if you use the bash man page enough (it doesn't take that much) you'll get a feel for its structure, so you can tell what's in there and about where it is before you actually look it up.
