shell-versions

A linter, not yet. You can use what I use: https://github.com/alganet/shell-versions It's a container with lots of shells that you can test. Like esvu but for the shell. Might have a little outdated docs, hit me with an issue if you use it and face any problems (I'm also the author).

Reviving a dead PHP bytecode vm for embedded systems: https://github.com/alganet/PHL --- Bootstrapping from an x86 image that is mostly source text (based on live-bootstrap): https://github.com/alganet/abuild --- Image with many shells, for testing script for portability: https://github.com/alganet/shell-versions

> and I didn't realize it was still maintained ksh _was_ unmaintained for ages. It stopped effectively in 2012, with some very small attempts at reviving it in 2016, 2018 and 2020. Then it was picked up for active development in 2021, and it lives here now: https://github.com/ksh93/ksh If you didn't already, you should open an issue there with your findings. -- Shameless plug: I keep some docker images with all those versions for testing, and many other shells too both historical and active (including osh!) https://github.com/alganet/shell-versions/blob/main/.github/...

https://github.com/shellfire-dev https://github.com/shellspec https://oils.pub/ There's probably more. The shell has a ____wide____ userbase with many kinds of users. Depending on your goal, the rabbit hole can go very deep (how portable across interpreters, how dependant on other binaries, how early can it work in a bootstrap scenario, etc).

shell-versions serves the same niche of nvm or esvu, but for shells. It is an indispensible tool for anyone who wants to write portable shell scripts. All shells are built and included in a single 40MB docker image (no manuals, no completions, just the interpreters). There are two image flavors: - latest: contains the two latest versions of each shell. - all: contains all shells we can build. The list of interpreters is: - bash: requires no introduction - busybox ash: the default busybox shell, other busybox tools not built - dash: the de facto shell for scripts - ksh93: the fastest most complete bytecode interpreted shell to be abandoned by AT&T - mksh / loksh / oksh: different distributions of the BSD port of the public domain ksh88 - osh: the oil shell, a python-based avant-garde interpreter - posh: if you think dash
