> When you start typing a command-line in Fish that matches a previously-typed command, it automatically shows the rest of the line as an available completion, and pressing ^F or the right arrow will complete it for you. ^R is more powerful, though; it matches at any point in previous commands, not just at the beginning. > The lack of this functionality actually really kills my ability to use any other shell. You can achieve that behavior in readline (which is used by bash, python shell, etc.) by changing the up/down arrows from previous-history/next-history to history-search-backward/history-search-forward. In ~/.inputrc: "\e[A": history-search-backward "\e[B": history-search-forward Note that you can still use ^P/^N for previous-history/next-history (or you can remap "\C-p"/"\C-n" as well).

That's how it works in Fish as well. user@system ~> echo wow wow user@system ~> echo something something user@system ~> wow█ ...press the up arrow and the current line becomes... user@system ~> echo wow█

  In bash, you hit Ctrl-R on the empty prompt and type "w": (reverse-i-search)`w': echo wow Hit return to execute, or any motion keys to start editing. It was the first thing I missed in Fish.

    I'm not sure how that is functionally different to mintplant's example? In fish you just type 'w' hit the up arrow and then hit enter to execute or any motion keys to edit. The same number of keypresses as well. Am I misunderstanding?

      Discoverability. With fish i would have to type something that would be a good match to the command i want to re-run before pressing up. With bash i type ctrl+r and start typing and i can continue to type until it's narrowed down to the correct command.

    In fish, you type "w" on the empty prompt and hit Up: > echo w̲ow Hit return to execute, or any motion keys to start editing. As long as you don't move sideways, you can repeatedly press up or down to navigate history. The underline is actually a highlight hinting at the substring match in the line. The difference is that typing an additional character after having moved in the history will start editing, appending the character to the line, instead of appending to the criteria. What I miss in all of them is looking for a fuzzy match instead of a substring match.

> kills my ability to use any other shell zsh definitely has this command, which I absolutely adore to be honest. ^R is one of my favourite features of the shell in general.

> You can achieve that behavior in readline No you can't. What I specifically described was the autocomplete of the line, not the ability to search history (which is manual complete instead of autocomplete).
