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.

Actually cd isnt a program. Your present working directory is managed entirely by the shell. If you type "type cat" in the terminal it will tell you its a program, but "type cd" says its a shell builtin. So yes, cd depends on the shell and zsh has some awesome quality of life features. This is not something you can do in bash.

I totally forgot! Makes sense that the implementation is shell-specific.
