Google ZX – A tool for writing better scripts
If I want to write better shell scripts I usually run shellcheck and adjust accordingly or if I need facilities not provided by the shell i switch to a full fledged programming language. Ans oh yes, `sh` is present almost on every BSD and Linux box for free so I consider it an important thing to at least be comfortable with.

How I use Nix in my Elm projects
When I run nix-shell at the root of the project it puts me in a Nix shell that contains, among other programs, caddy and shellcheck. Notice that in the shellHook I add the project's shell scripts to the PATH. So once I'm in the Nix shell I can, among other things:

Shellcheck finds bugs in your shell scripts
The error checks can be pretty arcane:
https://github.com/koalaman/shellcheck/wiki/Checks
zsh was originally supported, but unceremoniously removed: https://github.com/koalaman/shellcheck/issues/298
I've had great experiences with this tool, but, for some reason, this issue always makes me question taking too great a dependency on it.

Is there a syntax checker?
Similar to for instance shellcheck to check the syntax of shell scripts, is there an equivalent for the set of roff commands typically used in a (Linux) man page? I'm aware that e.g. pandoc permits the conversion of an other format (e.g., org) to both roff man and roff ms.

shellcheck, whilst not a script itself, I do find it useful when writing them.

The Bun Shell
I agree. I’ve written about this before but this is what murex (1) does. It reimplements some of coreutils where there are benefits in doing so (eg sed, grep etc -like parsing of lists that are in formats other than flat lines of text. Such as JSON arrays)
Mutex does this by having these utilities named slightly different to their POSIX counterparts. So you can use all of the existing CLI tools completely but additionally have a bunch of new stuff too.
Far too many alt shells these days try to replace coreutils and that just creates friction in my opinion.

Jaq – A jq clone focused on correctness, speed, and simplicity
This is exactly what Murex shell does. It has lots of builtin tools for querying structured data (of varying formats) but also supports POSIX pipes for using existing tools like `jq` et al seamlessly too.

The Case for Nushell
Stable is a problem because a lot of these shells don’t offer any guarantees for breaking changes.
My own shell, https://github.com/lmorg/murex is committed to backwards compatibility but even here, there are occasional changes made that might break backwards compatibility. Though I do push back on such changes as much as possible, to the extent that most of my scripts from 5 years ago still run unmodified.

Nushell.sh ls – where size > 10mb – –sort-by modified
This is similar to how my shell works. It still just passes bytes around but additionally passes information about how those bytes could be interpreted. A schema if you will. So it works as cleanly with POSIX / GNU / et al tools as it does with fancy JSON, YAML, CSV and other document formats.
It basically sits somewhere between Powershell and Bash: typed pipelines like Powershell but without sacrificing familiarity with all the CLI commands you already use day in and day out.
https://github.com/lmorg/murex
As an aside, I’m about to drop a massive update in the next few days that will make the shell even more intuitive to use.

VanadiumOS: Portable, multi-user Unix-like OS
It's possible without any kernel changes. My shell (https://github.com/lmorg/murex) already supports doing that.
The way it works is it uses fd3 to communicate schema information so it can natively support all the existing "dumb" pipes without any modification but any new tools can be written to send objects instead (albeit byte encoded).
It's not as elegant as PowerShell sending .NET objects natively, but then PowerShell doesn't work with existing CLI tools natively (it needs wrapper scripts to convert them into PowerShell commands). Whereas my shell is fully backwards compatible while still supporting a suite of additional functionality too.

Shell Script Best Practices, from a decade of scripting things
> getting the shell quoting hell right
Shameless plug coming, it this has been a pain point for me too. I found the issue with quotes (in most languages, but particularly in Bash et al) is that the same character is used to close the quote as is used to open it.m. So in my own shell I added support to use parentheses as quotes in addition to the single and double quotation ASCII symbols. This then allows you to nest quotation marks.
https://murex.rocks/docs/parser/brace-quote.html
You also don’t need to worry about quoting variables as variables are expanded to an argv[] item rather than expanded out to a command line and then any spaces converted into new argv[]s (or in layman’s terms, variables behave like you’d expect variables to behave).
