I was going to ask what to do if i use windows, but then i realize this is Lemmy and that you need a Linux computer to make an account

[-] SaltyIceteaMaker@lemmy.ml 48 points 3 weeks ago* (last edited 3 weeks ago)

Well it is also in linux memes

[-] CarbonatedPastaSauce@lemmy.world 30 points 3 weeks ago

Technically correct because you can’t make an account without the server.

[-] elidoz@lemmy.ml 13 points 3 weeks ago

I have no way to confirm or deny this, it may as well be true for all I know

(my first comment on lemmy! yay!)

Welcome!

[-] CaptPretentious@lemmy.world 4 points 3 weeks ago

And they use arch btw

[-] EherNicht@feddit.org 76 points 3 weeks ago

Thank you. My entire OS was so bloated now I have so much performance to spear.

[-] Voroxpete@sh.itjust.works 24 points 3 weeks ago

I'll bet your boot process is a lot shorter too.

[-] acockworkorange@mander.xyz 4 points 3 weeks ago

There’s even performance to sword and shield.

[-] ooterness@lemmy.world 43 points 3 weeks ago

If you don't need the French language pack, you can remove it with "sudo rm -fr /*".

[-] rustydrd@sh.itjust.works 30 points 3 weeks ago

It's asking for a password. What do I type? Sorry if this is a stupid question, I'm new to this Linux stuff.

[-] wreckedcarzz@lemmy.world 22 points 3 weeks ago
[-] AllHailTheSheep@sh.itjust.works 5 points 3 weeks ago

why is the password ******* lol

[-] acockworkorange@mander.xyz 3 points 3 weeks ago

A fine purveyor of internet memeology, you are.

> sudo rm -rf /*
Remove-Item: A parameter cannot be found that matches parameter name 'rf'.

[-] Ghoelian@lemmy.dbzer0.com 13 points 3 weeks ago

Does powershell have sudo? What does that do on windows, show a uac prompt or something?

[-] DmMacniel@feddit.org 15 points 3 weeks ago

It does now, since February this year. And yes it does show an auc prompt.

[-] AsudoxDev@programming.dev 8 points 3 weeks ago

Heh, inferior system keeps copying.

[-] AVincentInSpace@pawb.social 4 points 3 weeks ago* (last edited 3 weeks ago)

Microsoft realized they were losing basically the entire software development market to Linux so they started adding features like a pretty alright terminal emulator and a shell that almost looks POSIXcompliant if you squint (and don't pass any flags to its built in commands) and trying ineffectually to hide the fact that they were basically on their knees saying BLEASE COME BACK WE NEED YOU

[-] mlg@lemmy.world 24 points 3 weeks ago

No that only reduces disk space which only really mattered for hard drives.

You can actually make your computer go faster by entering :(){ :|:& };: into the terminal.

It'll tell Linux to max out the CPU performance.

[-] crimsoncobalt@lemmy.world 17 points 3 weeks ago

Does this really work? Wouldn't rm remove itself in /bin early in the process?

[-] rbn@sopuli.xyz 48 points 3 weeks ago* (last edited 3 weeks ago)

I think it would continue even after it's own deletion as the binary is already loaded into memory, so process is not dependent on the file system. Still doubt that it'll complete successfully. Most likely the system crashes in the middle.

[-] kirk781@discuss.tchncs.de 13 points 3 weeks ago

I thought - - no-preserve root also needed to be added as an argument for self destruct to completely work.

[-] elvith@feddit.org 11 points 3 weeks ago* (last edited 3 weeks ago)

Yes, though you could also do rm -rf /* afaik to not need --no-preserve-root

Edit: I just realized that the * is already in the meme. So this should already work as is. Alternatively you could always use the good old way of "act now and remove all French roots of your system: rm -fr / --no-preserve-root"

as the binary is already loaded into memory

That’s not the reason why it continues. It’s because there’s still a file descriptor open to rm.

[-] SpaceCadet@feddit.nl 18 points 3 weeks ago* (last edited 3 weeks ago)

In Unix/Linux, a removed file only disappears when the last file descriptor to it is gone. As long as the file /usr/bin/rm is still opened by a process (and it is, because it is running) it will not actually be deleted from disk from the perspective of that process.

This also why removing a log file that's actively being written to doesn't clear up filesystem space, and why it's more effective to truncate it instead. ( e.g. Run > /var/log/myhugeactivelogfile.log instead of rm /var/log/myhugeactivelogfile.log), or why Linux can upgrade a package that's currently running and the running process will just keep chugging along as the old version, until restarted.

Sometimes you can even use this to recover an accidentally deleted file, if it's still held open in a process. You can go to /proc/$PID/fd, where $PID is the process ID of the process holding the file open, and find all the file descriptors it has in use, and then copy the lost content from there.

rm doesn't remove memory in RAM

Since you forgot to add - - preserve-root It won't go too far. But at some point the system wants to load a file that is deleted and the kernel will panic. System crash. Delete incomplete. But rest assured, the important stuff is gone.

[-] SpaceCadet@feddit.nl 5 points 3 weeks ago

Since you forgot to add - - preserve-root It won’t go too far

Go on then ... try it.

Or don't because you will erase your system. (Hint: it's in the asterisk)

[-] Johanno@feddit.org 2 points 3 weeks ago

Or was it non preserve. I never tried it though. I guess a vm should be fine to test it. On the other hand I don't care enough.

[-] SpaceCadet@feddit.nl 2 points 3 weeks ago* (last edited 3 weeks ago)

The flag is called --no-preserve-root, but the flag wouldn't do anything here because you're not deleting root (/), you're deleting all non-hidden files and directories under root (/*), and rm will just let you do it.

[-] Contort3860@links.hackliberty.org 1 points 3 weeks ago

Pretty sure it's --no-preserve-root or something similar.

Remove it now

[-] bandwidthcrisis@lemmy.world 11 points 3 weeks ago

Never create a file named "-rf *" unless you really plan on keeping it.

[-] dwt@feddit.org 17 points 3 weeks ago* (last edited 3 weeks ago)
rm ./—rf\ \*

Am I missing something?

[-] bandwidthcrisis@lemmy.world 12 points 3 weeks ago

I'm not sure that you belong in this thread :)

[-] one_knight_scripting@lemmy.world 3 points 3 weeks ago* (last edited 3 weeks ago)

I'm not going to try it but... rm "./-rf *" would do the same? rm "./-rf \*" maybe?

[-] dwt@feddit.org 3 points 3 weeks ago

Couldn’t get single quotes to type on my phone, but best to always use them for problems like that, to completely get rid of shell interference.

if you use fish you can tab-cycle tour way to the file

[-] RecluseRamble@lemmy.dbzer0.com 3 points 3 weeks ago* (last edited 3 weeks ago)

I've been using Linux as my main driver for a couple of years now but I didn't know the list of reserved file name characters is so short.

I didn't believe '*' is allowed. That alone is so error-prone, it's insane. Backslash is allowed too - how do you escape that? Sometimes I think they giggled while writing the specs.

[-] Revan343@lemmy.ca 3 points 3 weeks ago

It's backslashes all the way down
