It may be a "not-so-attractive" tip for most of you, but I find it really useful when I want to edit a specific file (that is located alongside several ones, like a picture or a text file). Or when I've finished compiling something and I want to find the binary file asap. Saves me lots of time on really slow pcs (like a rpi zero).
Why not use bash-completion? The running example you gave is dangerous - you could end up running one or more of the wrong executables.
