#posixshell — Public Fediverse posts

After a hiatus (life got in the way), the BetterScripts POSIX Suite has a major update and a marginally less awful name: shtoolkit.

- What: A library of tools for POSIX-compliant shells.
- Why: Existing shell libraries tend to trade off portability, scope, or documentation quality.
- Where: https://github.com/BetterScripts/shtoolkit

Not every project needs this - but if you write portable shell scripts, it might save you some reinvention.

Happy to announce that I just published my #PolyglotScript v2.0.0 research report for #cli #commandline #shell. It consolidates #batchfile, #PowerShell, and #POSIXShell together into 1 single file that can run anywhere, everywhere without requiring to install anything.

Tested on #linux, #windows, and #macos. For #FreeBSD, still pending because GitHub does not officially facilitate #FreeBSD yet.

Check it out at:

#Poll: Curious about people's attitudes towards shell scripting.

Two part question:

1. Are you a DEVeloper (or working in a development-heavy role), OTHER-IT worker (such as a sysadmin, architect, anything in a non-development-heavy role), or NON-IT (accountant, doctor, whatever)
2. Do you HATE shell scripting, are you INDIFferent towards (or ignorant of) shell scripting, or do you LOVE it?

Should've made this a long time ago:

function ciglob {
    #case-insensitive glob generator
    echo "$*" |while read -N1 c; do
        case "$c" in
            [a-zA-Z])   echo -n "[${c^^}${c,,}]";;
            *)          echo -n "$c"
        esac
    done
}

~ $ ciglob "Hello, world!"

(Not the most useful example, but I did have a use case in mind when I wrote it ;)

🤔 Ah, the noble pursuit of reinventing the wheel with a POSIX shell in 2023! Kalua promises to turn your Wi-Fi #dreams into a reality (assuming you can navigate the labyrinthine #GitHub pages without losing your mind). 🌐 And don't worry, it's equipped with all the #buzzwords you need to impress your local IT club. 😂

I have figured out what's going on. My mental model was "processes launched by a shell inherit the file-descriptors of that shell", which is NOT TRUE. The *real* model is "processes launched by a shell inherit the file-descriptors of that shell, except when the process is launched from a non-interactive shell with the background operator (&), in which case the process' stdin is set to /dev/null".
