    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.

            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?))
