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!


    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.

    If the strings don't contain characters that help define a variable, like an underscore, how is it better practice to use curlies? It's it just for consistency? Have you had any style guides or linters critique the use of variables without them?

    More than anything, I find that it's a good habit to maintain in order to avoid simple mistakes. It also makes variables easier to spot in code and maintains consistency.

    foo=ding
    foobar=dong
    
    echo \$foobar
    
    

    Brackets make it explicit what you're trying to do. Do you want "dingbar" or do you want "dong"? I forget what the actual behavior is if you don't use brackets here, because I always use brackets for this reason now

    [–] subtext@lemmy.world 5 points 1 year ago (1 children)

    I believe the actual behavior here would be printing “dong” as the shell interpreter is greedy in its evaluation of variables.

    the actual behavior here is to echo the literal string "$foobar", because the $ sign is escaped. so no variable expansion will take place at all.

    Oh lol. It doesn't show the $ at all on my mobile app till I escaped it

    [–] vrighter@discuss.tchncs.de 2 points 1 year ago

    ah, so it's up to the client. I'm using jerboa, in this case

    You should use markdown's inline code (single `backtick`) and

    block code
    (triple backtick)
    

    tags. They are consistent across most markdown renderers (except Reddit's, which uses four-space indentations (like, who the fuck thought that was a good idea?))

    [–] RazorsLedge@lemmy.world 1 points 1 year ago

    I did use triple backticks
