Seriously this is a joke. Do NOT try this

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
- Well it is also in linux memes
- Technically correct because you can’t make an account without the server.
- I have no way to confirm or deny this, it may as well be true for all I know

  Welcome!
- And they use arch btw
Thank you. My entire OS was so bloated now I have so much performance to spear.
- I'll bet your boot process is a lot shorter too.
- There’s even performance to sword and shield.
  
  because it's spelled spare right? I got a joke
If you don't need the French language pack, you can remove it with "sudo rm -fr /*".
It's asking for a password. What do I type? Sorry if this is a stupid question, I'm new to this Linux stuff.

  why is the password ******* lol
  
  A fine purveyor of internet memeology, you are.
> sudo rm -rf /* Remove-Item: A parameter cannot be found that matches parameter name 'rf'.

- Does powershell have sudo? What does that do on windows, show a uac prompt or something?
  
  It does now, since February this year. And yes it does show an auc prompt.
  
  It's available here: https://github.com/microsoft/sudo
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.
Does this really work? Wouldn't rm remove itself in /bin early in the process?
- 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.
  
  I thought - - no-preserve root also needed to be added as an argument for self destruct to completely work.
  
  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.
- 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)
  
  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
  
  That’s not the reason why it continues. It’s because there’s still a file descriptor open to rm.
- 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.

  Go on then ... try it.
  
  Or don't because you will erase your system. (Hint: it's in the asterisk)
- rm doesn't remove things from memory, and binaries as small as rm can typically be entirely loaded into memory while running. Programs typically only run from memory, not the disk directly.
Everything is bloat mfs be like:
You wouldn't download /boot, would you?

  Remove it now
Never create a file named "-rf *" unless you really plan on keeping it.
- rm ./—rf\ \*
  
  Am I missing something?
  
  I'm not sure that you belong in this thread :)
  
  I'm not going to try it but... rm "./-rf *" would do the same? rm "./-rf \*" maybe?
- 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.

  It's backslashes all the way down
  
  Just use double backslashes for each backslash
- rm ./-rf
- if you use fish you can tab-cycle tour way to the file
Tecnically true
Don't tell me what to do!
- 💥
Joke's on you, I never figured out how to leave vim!
Why would you want that?
Please type this into my brain God
