Not everyone knows this stuff. Were you born with a Unix manual preloaded into your ROM? I wasn't.. my manufacturer thought that VMS would be the next big thing :(.

Maybe this will help some newbies make better use of their Linux systems. If you can only use the GUI, then Linux isn't much better than Windows for most tasks. It's when you learn to use the shell properly that it really starts to kick ass.

Switch your shell to one with auto-completion and go through each letter of the alphabet, hitting tab after each one and then viewing the manual page for each command you don't already know.

Wow. That's a neat trick.

Re:exciting (0)

Anonymous Coward | about 7 years ago | (#18665199)

Haha, but it does raise a question. Does the wall executable on AIX not only broadcast to logged users? Conversely, why would someone set gid on the wall command when the executable bit is already set for all users?

Any AIX gurus?

Re:exciting (1)

cortana (588495) | about 7 years ago | (#18665617)

I thought the setgid bit on the executable causes it to run with 'tty' as its gid; which presumably gives it the privilige to write to the various tty devices under /dev.

Re:exciting (0)

Anonymous Coward | about 7 years ago | (#18665897)

Yes, I checked on a FBSD box where /dev/tty is 600. My linux boxes all have /dev/tty set to mode 666.

Curiously /usr/bin/write is SGID TTY on every machine I checked.

Is there any reason for the relaxed /dev/tty permissions on linux?

Sadly though, there are probably people graduating from "computer science" programs who only know of 'processes' as something you get after pressing Ctrl-Alt-Del and clicking on the "Task Manager" button.

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.

Fortunately, my school uses gnat for the first tier of programming and gcc / javac for the second tier (the canonical form of the submitted assignment must run on the reference system in the lab, but you're free to develop using your own set of the GNU toolchain). I've had one higher-level course where the professor mandated Visual C for submitted assignments, but I still did all the work in GCC and stopped by the lab to compile the programs before class (since it was all just straight C programs with text or file I/O).

Re:They don't know how to spell "UNIX".... (0)

Anonymous Coward | about 7 years ago | (#18665405)

I can't speak for everyone, but at my school (SUNY Buffalo), all of the CS labs run Linux and your first lab in Intro I is configuring your user account with the command line. Submission of assignments is done via a command-line script and you have to ssh to one of the CS servers to read class anouncements. Maybe not all CS programs require knowledge of UNIX, but some certainly do.

loconet (415875) | about 7 years ago | (#18665855)

I think one of the big problems is not so much the lack of content offered in the classroom. The bigger problem I see IMHO is the lack of interest from students as a result of a poor introduction into what UNIX really is and how it will come to play in their careers (ie: beyond their gaming desktop).

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.

This is an article in a series (labeled Introductory to Intermediate) designed to introduce to the O/S. The first article in the series [ibm.com] talks about how to use find! You can't point at an O'Reilly book and call Stupid because you know what it talks about. The article is well written and explains processes perfectly for the intended audience, and not everyone is born with the intrinsic knowledge of how every O/S in the world works. Readers on this site want a world of O/S choices, but are so willing to bash an article that will help accomplish just that? And just because it gives a quick, sentence overview of PS and LS? Unbelievable.

The article may or may not belong on the front page, but claiming someone's illiterate for not knowing stuff like this, especially if they were in an Apple or MS shop? Heaven forbid.

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 applicaitons on servers and also for extending the interoperability between Windows and non Windows environments.

If anyone hires someone that doesn't understand basic 'computing principles', they are hiring computer 'illiterate' techs. PERIOD.

I was referring to the specific O/S implementation details outlined in the article, not the basic freshman year, "What is a process?" My fault for not being more specific in the closer, but I still stand by my statement.

If you hire someone who is supposed to be working with Windows/*NIX interoperability and hadn't a clue how UNIX works, then you have a problem and, yes, the new guy is illiterate for the task he is given. If you hire a developer to make a .NET application for a specific Windows architecture, then I wouldn't consider the user illiterate for not knowing the processes and binary code Unix launches on startup. At least, not in the incompetent sense that the word is being used here.

Re:What the flying f*ck? (1)

backbyter (896397) | about 7 years ago | (#18664899)

I agree that the article is beneath intermediate and advanced users of *nix .

As a noob, *nix illiterate, etc., I appreciated the article. I've had some past experience on a *nix box. I know very little. Of course, I didn't know a whole lot of JCL before I started working with mainframes either. I wouldn't expect anyone not familiar with a mainframe to immediately know the error codes produced by the system or what an initiator is either.

Like a previous posted has pointed out, due to the slashdot communities love of *nix you're getting windows converts here to this site. You can either help them along or drive them back to MS loving hands. I'm sure some of the converts are pretty sharp, and just might become the next big thing for *nix adoption by the mainstream.

I think most of the younger generation couldn't tell you how to list a directory using Windows command line. Why? They haven't had to. Since there's still a lot of work in *nix that can only be done by the command line, I say keep on posting articles like this. Maybe put them in a "Linux noobs" section, but at least help the prospective converts.

With several businesses now owning their own Unix mainframes, and with some futurists speculating that hobbyists may one day have full-fledged Unix systems in their basements, a detailed understanding of Unix operation -- including its intricacies, like these "processes" -- becomes increasingly important, even for people not charged with the operation of one of these computational goliaths.

Yea you are a big man now. You read an article and you understood it before you read the article. So you feel inclined to instult the fact that some people may not know this.
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.

The firehose is unfortunately implemented with Javascript. Some of us keep JS turned off because of its inherent problems with Security. It is the second biggest cause of problems right behind MS Windows.

And, sorry, noscript doesn't cut it. That's a bandage on top of something fundamentally broken.

I'm really disappointed with Slashdot on this; it's not difficult to implement the firehose without javascript. It seems they were too lazy to do so.

That's also the reason why I don't use digg. Granted, I'm not missing much. But if the folks at digg aren't technically competent to do things without relying on javascript, they can't possibly offer anything of technical interest.

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.

As a post-lesson extra credit bonus, after learning about ps, top, etc. they can try the commenting command named after the GWBASIC "REM" which stood for remark. The command you want is "sudo rm / -rf" which tells the machine to go into superuser ('cause you're a really super guy) and make remarks with a slash (remember, DOS uses forward slashes, unix uses backslashes) and the last part will note that the remarks you're making are going to be Really Funny!

Really, the article is great in explaining your manager how Unix processes work. It's a down-to-earth introductory explanation of processes and has some interesting information (which we all know, because we're all POSIX guru's) for newbie's and junior sysadmins switching to Linux/Unix/AIX

This is a great article (0)

Now, will someone tell me how to create a QProcess from the GUI thread of a multi-threaded Qt 4 application without the new process crashing?

Lavaps (1)

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.

Integrating the OS and browser is so last decade (0)

Cool people integrate the os and web *server.*

"You can view the entire list of processes using ps -a -w -x. (The format and specific flags of the ps command vary from UNIX flavor to UNIX flavor. See the online documentation for your system to find specifics.) -a selects all processes running on a tty device; -x further selects all processes not associated with a tty, which typically includes all the *perpetual system services*, such as the *Apache HTTP server*..."

Segfaults (5, Funny)

If it helps, you can think of a process as its own sovereign nation, with borders, resources, and gross domestic product.
Does this mean that illegal immigrants are responsible for my processes segfaulting?

Only on a system without memory protection. With memory protection, segfaults stop programs that generate illegal emigrants.

Re:Segfaults (2, Funny)

This is the traditional method. However, the new school of thinking is to use the "wall" program to limit access. E.g.,:

[gwb@usa] wall
Stay out, all of you!
^D

Message from gwb@usa:
Stay out, all of you!

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, but that doesn't matter.

This is true. In this case you need to use the "alien" program to convert the RPM (Revolutions Per Minute) package so that it can work with your system.

I saw slashdot transformed into Digg, with "slashdotit" links everywhere. That was supposed to be a joke, right? Because it's only funny the first time.
