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.

    Jokes on you, I use zsh, your silly bashisms have no power here.

    [–] [email protected] 4 points 8 months ago (1 children)

    Are you sure it doesn't work on zsh? It's valid POSIX shell code, and like bash, zsh is a superset of POSIX, at least if I remember correctly.

    This is not to goad you into destroying your filesystem. Replace the rm with something relatively harmless like echo "BANG! You're dead!" if you decide to test it.

    Key here is the outer [] and interaction of $[], test doesn't have == by default in standard posix, so no this isn't posix shell or bourne compatible. Tis but another bashism. I could probably force zsh into a more bourne mode to try it but its definitely not portable bourne shell its bash.

    $ [ $[ $RANDOM % 6 ] == 0 ] && echo rm || echo ok
zsh: = not found
$ zsh --version
zsh 5.9 (x86_64-pc-linux-gnu)

    == should be -eq for this to be posix/bourne portable, you could use = but -eq is for numeric comparisons so not quite right.

    fish and nu are the superior shells

    [–] [email protected] 1 points 8 months ago (1 children)

    Is fash like that fish shell only more fetch? zsh is obviously the best, its the omega end to shell names with the z (in latin alphabets so there).

    yeah i meant fish
