backtick in double quotes doing sneaky command substitution is a very funny shell scripting bug. very feasible to make that error unless you are really judicious about avoiding double quotes where pawsible

@aescling Sneaky command substitution? Isn't that the intended behaviour, that backticks always invoke a command and substitute its input, e.g. echo "Today is `date`"?
@vaporeon_ @aescling It's not obvious when you've never written bash before and did not know that ` was a command substitution and then accidentally wrote a script that called itself
@vaporeon_ @wallhackio i made a point of not teaching him backtick because you can’t quote it to purrevent splitting
@vaporeon_ @wallhackio (he did know this at some point though actually; it’s at least been mentioned to him on the fediverse befur. he just furgor)
@vaporeon_ @wallhackio i’m very much the type of cat to write code like it’s getting checked by a fairly strict linter at nearly all times
@wallhackio @aescling Whatever textbook or website or manual you use for learning Bash didn't mention the backticks? I use those all the time...
I forgot the difference between
`...`and$(...), though, maybe æscling can remind me? Is it just that the$(...)can be nested and the backticks can't?
