Ah, yes. This served me fairly well for some time. However, I also needed to remember the actual tool I used for the job. Was it ffmpeg? ffprobe? gifsicle? was it ImageMagick's convert? Not too bad if these are the only tools, but I also use pandoc, BluetoothConnector, pdftotext, qpdf, multiple AppleScripts, qrencode, system_profiler, fb-rotate, duti, sips, git... Bash history also remembers failed attempts, so I need to filter those out as I recall the successful one...

Wrapping the winning command with a memorable function makes it a bit easier for me to recall the right incantation via fuzzy searching. For example: "set default" (resolves to dwim-shell-commands-macos-set-default-app) vs "duti" (which I can never remember).
