Sorry, there's a lot of reading here, but I'm really confused!
tl;dr: Questions are highlighted.
Does anyone have handy a list of installed utilities in Ubuntu 15? I've done a few searches but I'm getting lots of results that differ from each other and that I feel aren't complete. I'm studying the tut on recommended linux apps, and its great, but I think I would be able to make better use of it if I could learn exactly what's already on my system.
Now for the embarrassing bit.
Maybe I'm overthinking this, but I feel that I lack a true understanding of what a utility is in linux. My understanding of a "utility" is that its a small executable/program that comes bundled with the os for the purposes of maintenance.
In my very small understanding of the computer universe, a utility is an executable/program like an "application" is, but an "application" is one that you download/install from a third party vendor for something unrelated to os maintenance.
I was confused when I first learned that "ls" was a "utility". I thought it was a "command". Isn't a command a direction you give a computer through the terminal?
So, if you made it through all that: Just how confused am I about the definitions of "utility" and "application"? I have this fear that an "application" just means stuff you buy for an expensive phone.
