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.
    •

    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 fork-bomb your computer.

    My install of Endeavour doesn't have it, and I haven't been able to figure out what package to install to add it. Also haven't tried very hard cause it's just a minor convenience but if anyone knows ...

    Oooh it's cause I'm using fish isn't it? Is there a way to add it?

    Had to check since this is something I've been wondering myself, but apparently not possible. From the fish FAQ:

    Because history substitution is an awkward interface that was invented before interactive line editing was even possible. Instead of adding this pseudo-syntax, fish opts for nice history searching and recall features. Switching requires a small change of habits: if you want to modify an old line/word, first recall it, then edit.

    However, for the use case here, with sudo:

    As a special case, most of the time history substitution is used as sudo !!. In that case just press Alt+S, and it will recall your last commandline with sudo prefixed (or toggle a sudo prefix on the current commandline if there is anything).
