Why not use bash-completion? The running example you gave is dangerous - you could end up running one or more of the wrong executables.
I wouldn't do this personally, but if I did, I think I'd at least pipe the results to head -n 1
to only act on the first result.
What about FZF? For example, I want to play a video file without digging through my files, I type fflpay and press ctrl-t which opens a fzf fuzzy finder. Type the incomplete name and select it. I would suggest this at least for the second example as running the wrong executable may get you in trouble. This is on the fish shell but I think other shells have similar possibilities. I also use this ctrl-t thing in combination with nvim or even cd.
Linux
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
