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!

    rm: remove [file name 1]?

    [–] [email protected] 17 points 3 weeks ago (1 children)

    I ran the command without sudo first. It had a bunch of permission errors removing stuff in /tmp. So I retried but with sudo

    /tmp is world-writable. If you get permission-errors, you should become suspicious.
    Also, whenever you write "sudo rm -rf" you should quadruple-check if that's really what you want to do.
    Non-interactively deleting entire directories in root space isn't something you should have to do normally.

    /tmp might be world writable but everything created in there belongs to the respective users.

    TIL. Makes sense, though.

    [–] [email protected] 3 points 3 weeks ago

    Exactly! if a service running under root creates a file, it belongs to root. if that file has permissions that don't allow other users to write (most do), then you can't delete it without sudo afaik

    Agreed, I should have been more careful. Fortunately it was just my downloads folder.
    In wanted to clear my /tmp, because I'd run out of space there for extracting an ISO file. It lives on a tmpfs, so space is quite limited.
