Community rules (click to expand)

1. Follow the site-wide rules

2. Be civil
  • Understand the difference between a joke and an insult.
  • Do not harrass or attack users for any reason. This includes using blanket terms, like "every user of thing".
  • Don't get baited into back-and-forth insults. We are not animals.
  • 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.
    • 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, no politics, no trolling or ragebaiting.
    • 4. No recent reposts
  • Everybody uses Arch btw, can't quit Vim, <loves/tolerates/hates> systemd, and wants to interject for a moment. You can stop now.
    • 5. πŸ‡¬πŸ‡§ Language/язык/Sprache
  • This is primarily an English-speaking community. πŸ‡¬πŸ‡§πŸ‡¦πŸ‡ΊπŸ‡ΊπŸ‡Έ
  • Comments written in other languages are allowed.
  • The substance of a post should be comprehensible for people who only speak English.
  • Titles and post bodies written in other languages will be allowed, but only as long as the above rule is observed.
    • 6. (NEW!) Regarding public figuresWe all have our opinions, and certain public figures can be divisive. Keep in mind that this is a community for memes and light-hearted fun, not for airing grievances or leveling accusations.
  • Keep discussions polite and free of disparagement.
  • We are never in possession of all of the facts. Defamatory comments will not be tolerated.
  • Discussions that get too heated will be locked and offending comments removed.
    • Β 

    Please report posts and comments that break these rules!

    Important: never execute code or follow advice that you don't understand or can't verify, especially here. The word of the day is credibility. This is a meme community -- even the most helpful comments might just be shitposts that can damage your system. Be aware, be smart, don't remove France.

    It's safe because it's sudo! Like sudo rm -rf /*

    At one of my prior positions they outsourced all the junior engineers to this firm that only had windows desktop support experience.

    Actual escalation I got:

    contractor: I am trying to remove this file that is filling the drive but it won't let me

    me: show me what you are doing.

    contractor (screenshot): # rm -f /dev/hdc

    another one did rm -rf /var to clear a stuck log file, which at least did solve the problem he was having.

    After that I sent out an email stating that I would not help anyone who used he rm command unless they consulted with a senior first. I was later reprimanded for saying I wouldn't help people.

    I've heard that before. "No. I won't close the circuit breaker while you're holding the wires." "Boss!..."

    Back in the olden days we used to nfs mount every other machines file system on every machine. I was root and ran "rm -rf /" instead of "./".

    After I realized that it was taking too long, i realized my error.

    Now for the fun part. In those days nfs passed root privileges to the remote file system. I took out 2.5 machines before I killed it.

    I still do. With NFS4 even more than ever. Won't let it go unless for a SAN.

    much?

    Like I said, olden days.

    Holy smokes. That must have been before 1989 (that's when RFC1094 was released, explicitely prohibiting to map the root user to UID 0). I thought, I was old...

    I did this in a cleanup script in a make file with an undefined path that turned the pointed dir to root after a hardware change

    thank rngesus I was in a user account with limited privileges

    Anyone remember that nvidia fix where a space slipped in like: rm -rf / nvidia ?
