No such thing. Ask away!

!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must be legitimate questions. All post titles must include a question.

All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.



Rule 2- Your question subject cannot be illegal or NSFW material.

Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding META posts and joke questions.

Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.

On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.

If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.



Rule 7- You can't intentionally annoy, mock, or harass other members.

If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.



Rule 10- Majority of bots aren't allowed to participate here. This includes using AI responses and summaries.

You have it backwards.

rm -fr /* removes the French language pack that comes preinstalled on your system.

/j

Creating a quick test vm isn't that hard, go nuts.

[–] CallMeAl@piefed.zip 9 points 5 hours ago

Surely you can tell us, Codewizard!

[–] remon@ani.social 6 points 6 hours ago (2 children)

It will delete everything in the directory after that, without asking for further confirmation.

[–] 0xKesh@lemmy.dbzer0.com 6 points 6 hours ago (1 children)

Unless it's on /, where preserve-root should be kicking in, unless the bypass flag is used (can't remember this one)

[–] Havatra@lemmy.zip 3 points 5 hours ago* (last edited 5 hours ago)

Not all systems have the preserve-root flag enforced, actually... I accidentally did the rm -rf / in a bash script (the variable for the path returned empty), and it irreversibly deleted a bunch of my system, including sudo and a big part of /etc, before I realized and did Ctrl+C. However the damage was done, rendering the system both unusable and unbootable. Fortunately I managed to recover some data, as the drive was not encrypted.

Edit: Yes, like a fool I ran the script as sudo... I am now older and wiser.

[–] Successful_Try543@feddit.org 2 points 5 hours ago* (last edited 5 hours ago) (1 children)

No, it does nothing.

$ mkdir test
$ cd test
~/test$ touch 1 2 3 4 5
~/test$ rm -rf
~/test$ ls
1  2  3  4  5

If you dont specify the -f option, which among other things tells rm to be quiet, it throws an error:

$ rm -r
rm: missing operand
Try 'rm --help' for more information.
[–] remon@ani.social 1 points 5 hours ago* (last edited 5 hours ago) (1 children)

Because you're using it on nothing.

$ mkdir test
$ cd test
~/test$ touch 1 2 3 4 5
~/test$ cd ..
$ rm -rf test
$ ls

No more test folder.

[–] Successful_Try543@feddit.org 3 points 5 hours ago* (last edited 4 hours ago) (1 children)

Exactly, but that wasn't the question.

[–] remon@ani.social 1 points 4 hours ago* (last edited 4 hours ago) (1 children)

What are you talking about? The does exactly what I said it does.

It only does nothing for you because you used it incorrectly (in the wrong folder without the required argument).

[–] Successful_Try543@feddit.org 2 points 4 hours ago (1 children)

The question is:

what happens when you give the command in the command line rm -rf ?

rm -rf * or here rm -rf test are different commands.

[–] remon@ani.social 1 points 4 hours ago* (last edited 4 hours ago) (1 children)

rm is the command, -rf are the flags and "test" is an required argument. So no, they are not different commands.

[–] Successful_Try543@feddit.org 2 points 4 hours ago (1 children)

No, the argument is not required, the command is valid. It's intentional and a neat feature that rm -rf alone without a specified file does nothing.

See e.g.: https://unix.stackexchange.com/a/553741

[–] remon@ani.social -1 points 4 hours ago* (last edited 4 hours ago) (1 children)

It does nothing because you used the wrong syntax but also set the flag that suppresses the output of syntax errors ...

Imagine someone would asked "What does a toaster do?"

I say "It toasts bread".

You come in with a picture of bread in a toaster and say "It does nothing".

I tell you "You have to press the button".

"You say "oh well, that wasn't the question, a toaster with the button pressed is basically a different device!"

Insert <Futurama not sure if trolling ...> meme.

You should obviously improve your reading skills.

The File argument is optional.

rm [OPTION]... [FILE]...

[–] remon@ani.social -1 points 4 hours ago (1 children)

Sure. And you should start learning basic bash skills.

[–] bizarroland@lemmy.world 3 points 4 hours ago (1 children)

Alright, I've read both of you guys' arguments. You're both right, but you're both talking about different things.

Successful try is responding with a literal direct computer-like response for OP's question. They are adding no additional qualifiers to the specific exact question that was asked, which is to say that the answer to OP's question is, it does nothing.

Reman, you were saying that anybody who was trying to use this command would obviously add a subject, would put the test or something else to it, would make an adjustment to the command in order to make it work and actually function.

And that is correct in practice, but that doesn't answer the question that was being asked literally. It answers the question the way a senior programmer would answer the question of a junior programmer.

Successful try's answer is the answer a computer would give.

So can you both please stop fucking arguing, hug it out, and move on?

[–] remon@ani.social 1 points 3 hours ago (1 children)

Successful try’s answer is the answer a computer would give.

I enjoy giving overly pedantic and technically correct answers as much as the next guy, but doing it on !nostupidquestions@lemmy.world seems like a dick move.

Watching this back and forth while I’m eating my chips 😅

rm -rf

For even more fun, add a single / at the end.
