Yes this is Basic Unix Command Line suff. But a lot of Unix users don't go beyond typing the command to run the program. Forking, Piping, Scripting, is more then what they really use. An some of the times these people who don't understand this are actually smarter then most of us. Say a Physicist who uses Unix to test their math or run complex simulations. Also there are a lot of people using Linux/Unix who were never formally taught how to use it. So they stick in the GUI, or Find and install programs that a simple small script can acomplish. I know you want to do your "I am an Alpha Geek" while thumping your chest. But if an article gets posted and you really don't care, then don't read it and move along. Because getting an article on information that you already know isn't a big deal, this is far more mature then say the latest Cool PC Mods.

Not everyone on Slashdot is at the same level as everyone else. While I've known all the stuff in the article for 10-12 years, I'm certain there's a significant number of people here that have no idea about process forking, or what the init process is.

While there will always be space for newcomers, there's a standard underneath it becomes somewhat pointless and adds needlessly to the signal to junk/noise ratio to consider adding an article. A newcomer's guide to Unix is one thing, but a brief overview of a small part of the system which will be useless to the majority of Slashdot readers, and will be too lacking in context for newcomers, fits well below that standard.

And TFA does not even include a link to one of the most important process viewing programs around - lavaps - which shows processes running on your system in a lava-lamp-esque display.
While the article is a bit elementary for most unix users, there are those who are not unix users who might need someday to know this.

On a side note, the new school of thinking works great with typical hack attempts. For example, if a user from systema (afgst) launches a remote exploit attempt, the new school suggests that you launch an attack against systemIRQ (interrupt request, for example). SystemIRQ has nothing to do with the attack,

You're vastly overestimating the CS curriculum, at least at my local State uni, if you think that UNIX anything is taught in the 100-level courses.

I have recently gone back to school to finish up my CS degree after having worked in the industry for several years and I'm surprised at the ignorance of UNIX/Linux's usefulness from people who have already taken a UNIX/Linux course in my school. It seems profs are jumping straight into bash scripting without properly introducing what UNIX really is, what the difference between UNIX and Linux is, how it is used today, why it is important to learn it, how it is different than Windows, the philosophy behind UNIX, how it is useful as a tool, etc. All students are being exposed to is a command line and some scripting. No context in the technology whatsoever. It is then not surprising that students come out of those courses thinking UNIX and Linux are useless since Windows/Macs do it better, easier. This results in them erasing whatever little knowledge they acquired as soon as exams are done with.

Um, I don't care if they are in a DOS/Novell shop. This is basic stuff and are also concepts that have relevance in all OSes.
As for Apple or MS shop? Ok, Apple uses a BSD interface to a Mach kernel and is very much a *nix architecture. In the MS Shop, NT also includes a full BSD subsystem that is used for running *nix applicait

I thought that the slashdot community was supportive of people migrating away from windoze to the linux world. TFA covers things that are not obvious to people that don't have *nix experience. It was a nicely written article. It might spur discussion on further basic knowledge needed to deal with linux. The whole community of "nerds" includes slide-rules to slashdot. Not every nerd is a sysadmin. To me this was useful. I already had learned 75% but had forgotten some and a bit was new and might be handy. That is "stuff that matters" to me. If nothing else cranky sysadmins, when posed with a question about something this basic, could roll their eyes condescendingly and give a link to this handy page.
The better question is why is this posted under "devcelopers"?
