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.
That’s definitely not standard. Maybe your distro or shell has this configured that way. The actual standard thing is that each directory has entries for
.and.., as you can see inls -a.Yup, that’s what I’ve always understood. Seems like this is zsh-specific, since using the default Terminal app with zsh also works. Do you know if other shells (fish, csh, etc.) support this syntactic sugar? Anything else zsh has that I should know?
Well, I’m a
fishguy, so there’s two things I can tell you:fishdoes not support this particular syntactic sugar.fish-like autosuggestions inzshvia this: https://github.com/zsh-users/zsh-autosuggestionsThough I use fish as well, this is some good info 👍.
Eshell, the Emacs shell, supports this feature out of the box, regardless of the OS it runs on.
