    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

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

            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

    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.

      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.

          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”

              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

        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), 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.

      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)

          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.

            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.
