    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

    [–] [email protected] 48 points 1 month ago* (last edited 1 month ago)

    Well it is also in linux memes

    [–] [email protected] 30 points 1 month ago

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

    [–] [email protected] 13 points 1 month ago (1 children)

    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!

    And they use arch btw

    [–] [email protected] 76 points 1 month ago (3 children)

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

    [–] [email protected] 24 points 1 month ago

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

    [–] [email protected] 4 points 1 month ago (1 children)

    There’s even performance to sword and shield.

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

    [–] [email protected] 30 points 1 month ago (1 children)
    > 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?

    [–] [email protected] 15 points 1 month ago (1 children)

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

    [–] [email protected] 9 points 1 month ago (1 children)

    Heh, inferior system keeps copying.

    [–] [email protected] 5 points 1 month ago* (last edited 1 month ago) (1 children)

    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

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

    [–] [email protected] 22 points 1 month ago (2 children)
    [–] [email protected] 5 points 1 month ago

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

    [–] [email protected] 3 points 1 month ago

    A fine purveyor of internet memeology, you are.

    [–] [email protected] 25 points 1 month 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.

    [–] [email protected] 16 points 1 month ago (4 children)

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

    [–] [email protected] 48 points 1 month ago* (last edited 1 month ago) (2 children)

    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.

    [–] [email protected] 13 points 1 month ago (1 children)

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

    [–] [email protected] 12 points 1 month ago* (last edited 1 month ago) (1 children)

    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"

    [–] [email protected] 1 points 1 month ago (1 children)

    i dont get why you can't just do sudo rm -fr /

    [–] [email protected] 3 points 1 month ago

    because it won't let you do that:

    elvith@testvm:~$ sudo rm -fr /

    rm: it is dangerous to operate recursively on '/'

    rm: use --no-preserve-root to override this failsafe

    [–] [email protected] 2 points 1 month ago

    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.

    [–] [email protected] 18 points 1 month ago* (last edited 1 month 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

    Everything is bloat mfs be like:

    [–] [email protected] 12 points 1 month ago (1 children)

    You wouldn't download /boot, would you?

    [–] [email protected] 8 points 1 month ago* (last edited 1 month ago)

    Basically

    Obscure

    Optimal

    Trojan

    Remove it now

    [–] [email protected] 11 points 1 month ago (4 children)

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

    [–] [email protected] 17 points 1 month ago* (last edited 1 month ago) (2 children)
    rm ./—rf\ \*
    

    Am I missing something?

    [–] [email protected] 12 points 1 month ago

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

    [–] [email protected] 3 points 1 month ago* (last edited 1 month ago) (2 children)

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

    [–] [email protected] 3 points 1 month ago (1 children)

    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.

    [–] [email protected] 1 points 1 month ago

    I always forget about the single quotes.

    [–] [email protected] 1 points 1 month ago

    If you do want to try, just start a docker container and try inside there. That should negate all risk

    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.

    [–] [email protected] 3 points 1 month ago

    Backslash is allowed too - how do you escape that?

    It's backslashes all the way down

    [–] [email protected] 2 points 1 month ago

    Just use double backslashes for each backslash

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

    [–] [email protected] 9 points 1 month ago

    Tecnically true
