$ indicates that the string following is an env variable, but you just have a closing quote, so bash is confused.
If you want the literal character $ in your command, you must escape it: \$
Edit: afaik my answer does not change based on the fact that this is fish instead of bash or zsh. The $ is outside of the single quotes, and is thus being interpreted as an env var anchor.
Of course. It could work totally different from bash.
To be fair I saw some cool fish stuff and thought about using it but when maintaining a few thousand servers with bash its not viable to load an alternative shell to all of them.
They are not identical, but more they are quite compatible, most of Bash syntax and built-in commands work on Zsh as well. From what I’ve heard, Fish differs from them a lot. I use primarily Zsh, but sometimes run Bash if I need it for something (before ** started working on Zsh, I used Bash globstar when I needed it, for example).

The actual folder is 'folder'$'\003' .
In that case, I think you want
Note the double escape before
003, which will render to the character literal\Alternatively, start typing
And then hit tab until
fishautocompletes the directory you want to kill, and run it.Side note: i would absolutely not tolerate directories named like that lol
Thanks for the tip.
Is this some school task...? Why is there a folder with such a name 😅
Apparently yes. I'm learning things on my own.
how did you decide which parts to quote..?
I simply copied down the commands in the lesson.
might have been clearer to just link to that
This syntax works for me on Bash and Zsh. Your shell might have a different way of writing escape sequences.
Bash and Zsh are identical ??

fish expected a variable name after $
