Shell script compiler

Project mention: Execute a shell script by double-clicking? | /r/Ubuntu | 2023-05-05

You can turn a bash script into a binary with shc, it would work similarly to an appimage.
ast

AST - AT&T Software Technology

Project mention: A Generation Lost in the Bazaar (2012) | news.ycombinator.com | 2023-10-19

I suspect the intended point of comparison is the monolithic Unix of old, where the entirety of the code of the system is (hopefully, ostensibly, allegedly) developed with a single vision, except for the applications in the narrowest sense of the word (e.g. the particular piece of numerics you need to design your airplane or whatnot, but not the editor you used to write it, the cluster scheduler you used to run it, the typesetter you used to write down your results, or the 3D viewer you used to present them).
One example that’s just plain interesting to read to see what things people were exploring (because, let’s admit it, historical Unix source gets plain boring after a while) is AT&T Research’s https://github.com/att/ast.

ksh 93u+m: KornShell lives! | Latest release: https://github.com/ksh93/ksh/releases

Project mention: Faster Shell Startup with Shell Switching | news.ycombinator.com | 2024-01-16

David Korn's ksh93 was passed on to a new set of developers, who attempted to release a new version; AT&T rolled back these changes due to performance problems which raised questions of support status. It does appear that ksh93 development has resumed, and a new version was released late last year.

The independent pdksh spawned mksh, which is the default shell used in Android (as it has a BSD license); mksh appears to be very much active.

OpenBSD also forked oksh from pdksh. This is certainly well-maintained.
