Some other options: 1. Piping into `fzf -m` (use tab to toggle selections and built-in search to filter options). 2. Percol https://github.com/mooz/percol (also has filtering, use ctrl-space to toggle selection).

Related: percol utility allows to narrow a process output interactively https://github.com/mooz/percol I use it all the time to select a command from my shell history. It is a very convenient addition to zsh-autosuggestions (one of those things that you use hundreds times per day without even thinking about it).

You seem like the kind of person who'd appreciate Percol[1]. It's fantastic for shell history. I have it bound to Ctrl+R: history | percol --prompt-bottom --result-bottom-up I'm using fish, so the whole thing looks like this: function _percol_key_bindings function __percol_ctrl_r set tempfile (mktemp) history | percol --prompt-bottom --result-bottom-up >$tempfile and commandline (cat $tempfile) commandline -f repaint rm -f $tempfile end # Bind Ctrl+R to percol history function for now bind \cr '__percol_ctrl_r' end [1]https://github.com/mooz/percol/

They use this tool extensively at Spotify. I saw a presentation by https://twitter.com/jooon, when I was over there in September last year. It is a really cool tool. Especially since they use JSON internally for almost all of their data representations. Jq + Percol[1] is kind of cool. [1] https://github.com/mooz/percol - was on HN a few days ago.

It's great for tab-completion of remote paths for scp & friends. It does have a few quirks though. One that I've noticed is (IIRC) that closing a shared session isn't sufficient to pick up new groups membership when you reconnect. You actually need to kill the master connection as well[0]. The syntax for shutting down a master connection is a bit clunky as well: ssh -O stop -S ~/.ssh/mux/socketname hostname I've been meaning to make a little script or 2 that finds the current mux sockets and tests them with -O check and give you a list of simple IDs you can 'ssh-mux-kill $id' or something. In fact, it'd probably be a nice use for percol[1] [0] There might be other ways of refreshing group memberships, but I don't know of any. [1] https://github.com/mooz/percol
