Ask HN: Is there a GUI for bash shell?
ncurse, dialog, zenity[2]. i/o buffering may be an issue [3a,3b]
Assuming using same account, use history command to show past commands[0a, 0b]
'load random example' on shellcheck using own custom examples from history command.[1]

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:

Regex support to list modules in .cabal?
I have also seen some projects on github like ShellCheck which first make a library, expose all the modules and then simple add that do build-depends of the final executable. Is this the recommended approach than having just one executable and adding all the modules to other-modules:?

Shellcheck finds bugs in your shell scripts

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.

And finally, checkbashisms if you intend on making pure posix scripts that are compatible with debian/ubuntu's dash. It is part of the debian's devscripts suite, but is often individually packaged in other distros.

Or you could learn from a guide written by people who have suffered decades of experience of the pitfalls of shell scripting and have shared their woes.

I support projects like this for purposes of exploration and practice. But don't expect people to use it when there are already well established projects out there like: https://github.com/mvdan/sh

similar to shellcheck?
There are also: - shfmt - sh - bash language server - bashate
- shfmt - formatting comments issue
