    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

        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

              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?))
