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 is barebones, you should see this one
- yash: yet another shell!
- zsh: the default shell on macos
There are 20+ year versions there of many of these and all recent versions. These should cover many popular and niche use cases.I'm looking for general feedback and overall portable shell discussion. Thanks!
