1. Follow the site-wide rules

2. Be civil
  • Understand the difference between a joke and an insult.
  • Do not harrass or attack members of the community for any reason.
  • Leave remarks of "peasantry" to the PCMR community. If you dislike an OS/service/application, attack the thing you dislike, not the individuals who use it. Some people may not have a choice.
  • Bigotry will not be tolerated.
  • These rules are somewhat loosened when the subject is a public figure. Still, do not attack their person or incite harrassment.
  • 3. Post Linux-related content
  • Including Unix and BSD.
  • Non-Linux content is acceptable as long as it makes a reference to Linux. For example, the poorly made mockery of sudo in Windows.
  • No porn. Even if you watch it on a Linux machine.
  • 4. No recent reposts
  • Everybody uses Arch btw, can't quit Vim, and wants to interject for a moment. You can stop now.

  • Please report posts and comments that break these rules!

    No, this is a very old joke that uses the fact the command has "fr" in it to trick people about what the command does. Joking aside, here's what the command actually does:

    rm is the command to delete files and folders

    -f is the force modifier. This means it'll keep going even if it encounters problems and just delete as much as it can

    -r is the recursive modifier. That means it'll go down every folder it sees in the target and delete the contents as well, and delete the contents of folders of folders, etc.

    / is the target. This is the root of the filesystem. If you're used to Windows, that's like targeting C:.

    Put it all together, and this command basically deletes your whole filesystem. A safeguard was put in place a while back due to people meming about this and causing newbies to delete their whole system. Now it won't work unless you put in --no-preserve-root, which tells rm that yes, you really mean it, please delete my whole system.

    /* as the target works around that safeguard, because technically deleting everything in root is not the same as deleting root itself.

    Oh, like a more sophisticated version of the old "put your phone in the microwave"joke!

    Thank you, kind person.

    Or the less destructive, "Press Alt+F4 to triforce."
