Simplifying Complexity, One Answer at a Time!
Rules
$ 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.
They are using fish, FYI. Not sure how much of a difference this makes.
Fish is different ?
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.
The actual folder is 'folder'$'\003' .
In that case, I think you want
rm -rf "'folder'\$'\\003'"
Note the double escape before 003, which will render to the character literal \
Alternatively, start typing
rm -rf \'fo
And then hit tab until fish autocompletes 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.
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 ??
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).
how did you decide which parts to quote..?
I simply copied down the commands in the lesson.
fish expected a variable name after $
