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 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!

    Wait you guys don't sudo echo o > /proc/sysrq-trigger?

    [–] SteveTech@programming.dev 34 points 1 year ago (3 children)

    I think you'd have to do echo o | sudo tee /proc/sysrq-trigger, otherwise sudo only works for the echo, not the write.

    Holy shit the reason for tee never really clicked until I saw this post. I’d used it in pasted commands, but it had always seemed superfluous.

    It writes to a file like >, and echos it back at the same time; in this case the latter isn't needed (we're just using it to write with sudo), but it's good to know.

    echo c | sudo tee /proc/sysrq-trigger 🫣

    Ah I guess I just use sudo bash a lot 😅
