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.
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
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?))
find “${HOME}/docs/”
You want the full path in quotes so that paths with spaces are handled properly. Brackets are good practice when concatenating strings.

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

I did use triple backticks
“Concatenating”….
…. That sounds either exceptionally painful or extremely fun.
Quite possibly both…
This shit fucked me up so much when i was learning linux stuff. Especially cause a lot of my file paths had spaces. This is the way.
The lesson for me was not to create paths with spaces. There are none in Linux unless you create them.
Too late lol.
