Just realized I can just use "..." to go back two directories! Is this a zsh feature? (lemmy.ca)

I accidentally discovered that both "cd ..." and "..." work, and moreover, I can add more dots to go back further! I'm using zsh on iTerm2 on macOS. I'm pretty sure this isn't a cd feature. Is this specific to zsh or iTerm2? Are there other cool features I just never knew existed??

I'm so excited about an extra dot right now.

Each instance of . is a relative level to your current directory. ‘cd .’ changes your directory to your current directory. ‘cd ..’ (edit: on mobile this keeps changing to three periods but it should just be two) changes it to the directory above, ‘cd ….’ would change it to three directories above. This is standard in *nix (Unix and Linux) operating systems

Edit 2: this is very wrong

No, it very much isn't.

Yeah you’re right. I wrote this before sleep and after sleep it’s hilariously wrong lol. Oh well I’ll leave it as a cautionary tale
