The error message shows that the compiler has been successfully found, just that it can't find the source code (hello.f90). You need to use an editor like vi to create a fortran source file named hello.f90 and try the compiler again.
As to learning Unix, I'm partial to "Essential System Administration". Others will point you to the "Unix System Administrator Handbook". From what you've said, I think the second one would be a better choice. I've read them both and in my opinion ESA is more for someone who's done administration before and has a good frame of reference.
You don't need to do everything in the book since you're not administering a server, however either will be a good reference in how things Unix work.
I'll have to leave fortran references to someone else though. It's been 20 or so years since I touched fortran

what's the point of having loopback when you can just ping your local ip address? for example if my ip is 1.1.1.1, why can't i just do ping 5 1.1.1.1 instead of ping 5 127.0.1.1? it seems to me the only point in having it is for the sake of convenience? (2 Replies)

NAME
gvrng - An interactive, introductory programming language.
SYNTAX
gvrng [world file | program file]
DESCRIPTION
Guido van Robot is a project developed by advanced high school students for use by their peers as a learning tool and precursor to the fur-
ther study of programming with Python. It is a minimalistic programming language providing just enough syntax to help students learn the
concepts of sequencing, conditional branching, looping and procedural abstraction. It's biggest strength is that it permits this learning
in an environment that combines the thrill of problem-solving with instant visual feedback. In short, it is an interactive, introductory
programming language that is excellent for learning the basic concepts of programming, applicable in any high-level language. Best of all,
it's a whole lot of fun, too!
At this point, you are probably asking yourself, "What is GvRng, specifically?" The gist of it is that it is a robot represented by a tri-
angle on the screen that moves around in a world made up of streets and avenues, walls and "beepers", which Guido can collect or set. His
actions are completely guided by a program written by the user.
