Just on your first suggestion, this also means that if a person or process can drop a file (unknown to you) into your ~/bin/ then they can wreak havoc. Eg they can override `sudo` to capture your password, or override `rm` to send your files somewhere interesting, and so on. Btw on the second suggestion, I think there's a command named `command` that can help with that sort of thing, avoids recursive pitfalls.
The issue of rootless malicious command overrides is solved by typing the whole path, such as "/bin/sudo".

You can use an alias, which takes priority over $PATH. e.g. I have this in .zhsrc to override the "claude" executable to run it in the OS sandbox: alias claude="sandbox-exec -f ~/agents-jail.sb ~/.local/bin/claude --dangerously-skip-permissions"
How does your sandbox ruleset look? I've been using containers on Linux but I don't have a solution for macOS.
My goal is to prevent Claude from blowing up my computer by erasing things it shouldn't touch. So the philosophy of my sanboxing is "You get write access to $allowlist, and read access to everything except for $blocklist".
I'm not concerned about data exfiltration, as implementing it well in a dev tool is too difficult, so my rules are limited to blocking highly sensitive folders by name.

#125Using commas in filenames feels kind of weird to me, but I do use a comma as the initiator for my Bash key sequences. For example: ,, expands to $ ,h expands to --help ,v expands to --version ,s prefixes sudo You put keyseqs in ~/.inputc, set a keyseq-timeout, and it just works.
would an alias just work in this use-case?
openssl ,v
to expand to... openssl --version
readline seems like the way to go.Then again most of the examples OP gave are usually available as short options, and aliasing ,s to sudo is certainly possible. So the only one which makes sense to me is ,,=$. But it's probably not worth the trouble to my muscle memory.

#126I didn't like the idea. I prefer the alternative approach: _I_ decide the order of dirs in the PATH env. If I introduce an executable with a name, that overrides a system one - I probably do that intentionally. If I introduce an alias (like `grep='grep --binary-files=without-match --ignore-case --color=auto`) that matches the name of a system binary - I probably do that intentionally. And if I EVER need to call grep…
Either adding your script directory in front of the PATH, or creating `alias` that provide a full path to your script where a conflict exists, makes a whole lot more sense to me. I've never had this collision problem yet, despite appending my script directory to the end, but I'll use either of the above solutions if that ever becomes a problem.
You use shadowing to fix issues where you install some software that expects you to have a sane and ~recent version of some tool like git, but you don't as your system provides that binary and unfortunately it is either not sane (not GENERALLY sane [while it could be sane for system scripts]) or not recent enough. In that case the program's function would simply fail if it would call the system's binary and you shadow the binary with your version to fix that.
> adding your script directory in front of the PATH
That's a poor advice for the scripts you call relatively frequently. Instead, (as a general approach, we aren't discussing some particular script) don't use shadowing for scripts: just pick a non-conflicting script name and append the script's dir to $PATH.

#127I tried a variant or this idea so many years ago after I leaned git and rearranged some of my personal tools as subcommands (like git) of a single executable named "dude," It went weird pretty quickly...

#129I appreciate the idea, but the comma just looks horrible to me as part of a filename. I can imagine someone unfamiliar with the naming scheme to get confused. I'd prefer to use underscore (when writing BASH scripts, I name all my local variables starting with underscore), but a simple two or three letter prefix would also work. I don't like the idea of a punctuation prefix as punctuation usually has a specific meanin…
I use my_ as a prefix.
I would replace underscore with “-“ or “.”

If I ever wanted to achieve what you initially wanted to achieve - I could use something like
alias -s sh=sh
alias -s bash=bash
alias -s zsh=zsh
Just like I do bind .txt and .conf to 'less', .pdf to 'qpdf', .json to 'ijq', video formats to 'mpv' and so on.
