  • 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.

    fish, the friendly interactive shell, is a commandline shell intended to be interactive and user-friendly.

    fish is intentionally not fully POSIX compliant, it aims at addressing POSIX inconsistencies (as perceived by the creators) with a simplified or a different syntax. This means that even simple POSIX compliant scripts may require some significant adaptation or even full rewriting to run with fish.

    Fish is not the worst in this regard, because:

    • The defaults are pretty good, so you don't typically need a config file for it to be usable.
    • As of version 4.0, Fish is (experimentally) available as a single executable for download from their GitHub page. So, even on hosts where you can't install anything, you may still be able to copy that executable file onto there and use it.

    But there may still be situations where it's annoying, like if you're working in a container, then you likely don't want to mount your fish executable every time.

    But I also have to say I don't find it too big of a deal.
    I still use Bash for scripting (just throw a #!/bin/sh or #!/bin/bash at the top of your script, like you should anyways), and then for interactive use, not that much of the shell syntax comes into play anyways.
    And if I ever do need to copy a complex Bash command into an interactive shell, I can just run bash, then run the command in there and then exit back out.
