Learn the ways of Linux-fu, for free

[syngrog66]

This is one of those HN 'anti-exemplar' posts where I can't tell if the people are serious and sincere or whether they are all involved in a satirical group troll or a self-promotion ring. Or both.

In broad strokes:

"Finally! After 20+ years now there's a way I can learn Linux!"

"If only a way I could 'save' this and revisit later... or a way to 'share' it with others... hmmmm..."

and someone just asked how to wipe a hard drive (?!)

etc

and 415 upvotes?

It is not April 1st, and I'm not on The Onion. If everyone is sincere, great, and good for you, but I'd love to know that.

Is it because school is out for the summer now? At least here in the US.

And I'm curious: did any one else have a similar reaction?

Actually I find that page relatively nice and well structured, not looking like some concated man pages from the 80s. And there are probably lots of experienced people (I know some) who had relatively little Linux contact before, who somehow ended up on it, doing web development exclusively on the app layer with occasional contact with the rest of the environment, who would be happy to have such a resource. It has an ok balance of in-depth understanding and concrete examples, which is not always true for man pages, and it is structured differently ("problem -> understanding -> solution" rather than "solutions -> understanding of the solutions -> find the correct problem").

I agree. It looks nice but that's it. It's full of errors and misinformation.

People would be FAR better off with "Linux for Dummies" which despite the name is an excellent book.

And it has a free "cheatsheet" : http://www.dummies.com/how-to/content/linux-for-dummies-chea...

I wish HN had a save post feature similar to Reddit. I'm not really a bookmark guy and this is exactly the kind of site I know would be a life saver some time in the future.

[kawera]

If you upvote a post you can access then later by clicking on "saved stories" in your profile page. There is a "saved comments" too.

Heh, bookmarks do not help. I am a compulsory bookmarker, but i suck at finding stuff i have bookmarked maybe a month ago...

[OneOneOneOne]

Good point. Does anyone have a good web based bookmark tool? I hop between a dozen machines on different networks so keeping bookmarks is kind of tedious.

>By default the echo command takes the input (standard input or stdin) from the keyboard and returns the output (standard output or stdout) to the screen.

This isn't right is it? Echo doesn't read anything from stdin:

    echo <<< HelloWorld
    

Does this command makes any sense?

    $ ls | grep *.txt /tmp
    grep: /tmp: Is a directory

I found the whole text-fu section quite confusing...

[jwilk]

This doesn't work either:

    $ echo The quick brown; fox jumps over the lazydog > sample.txt
    The quick brown
    bash: fox: command not found

[tangue]

Yes I wouldn't recommend this one. And the emacs part is useless (it's a half baked cut and paste of the tutorial)

This is a beautiful site for teaching the command line, while not being too over the top in its aesthetic...I'm on my iPad so I'm not seeing the issues others are having on mobile

"During this time other efforts such as BSD, MINIX, etc were developed to be UNIX like-systems. However, one thing that all these UNIX like-systems had in common was the lack of a unified kernel."

BSD and MINIX lack a Unified kernel? What?

[xchaotic]

Learn the CSS foo. Layout and navigation completely broken on mobile

[stinkytaco]

That's because this is the year of the Linux desktop. /s

(Yes, I know Android is linux, but you know what I mean you pedantic know-it-alls).

[edwcar13]

This is for OP if its their project. Feedback your mobile version needs work. I see that it's responsive, but a lot of the content is off the screen.

[simplexion]

Don't teach people ifconfig! It's all about ip now.

[HeadlessChild]

Yes, I can't stress this enough. I teach all the users at my company to use ip instead of ifconfig.

[ake1]

think some keys got mixed up here:

h or the left arrow - will move you left one character

j or the up arrow - will move you up one line

k or the down arrow - will move you down one line

l or the right arrow - will move you right one character

There are a lot of little typos (such as stating '..' and '-' arguments for 'cd' labeled as "previous directory" or suggesting Ubuntu uses Debian because it's made by Canonical). I wonder the best way to contact the author about revising these small but obviously not terrible errors.

[gravypod]

There doesn't seem to be any mentions about pacman in the package managers section.

It's a shame, I've felt wonderful switching to Arch based distributions just due to pacman.

On my Blackberry the site does not layout well. It might be worth looking at % of users coming from mobile and if you see a lot of that kind of traffic fixing the layout.

[satysin]

The fact your username is IE6 and you mentioned rendering issues makes me smile :)

[preek]

Renders nicely on my iPhone 6S.

[keeganjw]

I was just about to jump into the world of Linux and this is perfect.

[ApolloRising]

This is really well done. Can you talk a bit about how you built it?

[known]

Good one. Thank you.

[taivare]

Anyone offer advise on a good program for wiping the hard drive on an older PC - pentium / Duo core 2 ; 2009 for a fresh install of Ubuntu or some other Linux distro -install.

[ychompinator]

Spent ages trying to work out what the hell Linux-FU is ... then eventually realised it's like kung-fu .. wtf.
