Terminal/iTerm Autocomplete “greyed” functionality

auto-completeitermterminal

Not too sure how to describe this… but I saw this on a person's computer a cafe today and didn't get a chance to ask him what plugin/application he was using —

I think it best to illustrate with an example:

Say there's a directory with three folders, 'kitty', 'doggie', and 'frog'.

Typing cd f would make the letters rog appear after the 'f', but rog would be in a lighter color of text (a greyed color) — it was a sort of "visible autocomplete", not sure what else to call it. Anyone know how to achieve this? Thanks.

This is a feature of the fish shell (Friendly Interactive Shell).

fish's scripting syntax is also quite a bit different from bash and zsh's. If you use zsh, you can also try the zsh-autosuggestions plugin on Github.
