pairing this with yaegi [1] would be interesting. You could having a REPL open doing os operations and when you get the data looking like you want, you select which lines to save to a file. [1] https://github.com/traefik/yaegi

Not OP, but the usual talking points were covered pretty well in this thread from yesterday: https://news.ycombinator.com/item?id=42884337 To sum it up, the biggest complaints are error handling, null handling, and dependency management. And y’know, being backed by a company of ghouls hellbent on extracting value for themselves at the expense of society.

dependency management in Go is best in class what are you talking about? go mod is that good.

I use Go a lot and I completely disagree. I have also used Ruby a lot and even though I prefer writing Go most of the time (it depends on the task) bundler is far better.

go mod is the second best I've used for sure, but if someone releaed bundler-but-for-go I'd switch to it in a heartbeat.

That’s why you install gnu-coreutils. Eliminate the difference.

Why shouldn't it be as easy to write system administration programs in Go as it is in a typical shell? 1. Shell scripting offers infinite functionality. You can shell script with any program in any language. All it needs to do is take input and produce output. And if the functionality doesn't exist, you can create it on the fly, without having to follow any of the traditional rules of programming. 2. Shell scripting…

You can run a shell command from a language you like so they're just as flexible. Go and many other languages have Exec (or equivalent).

The major reason shell scripting is nice is because its portable with a copy/paste and HelloWorld.sh doesn't need a compiler or a VM or even any preceding incantation to run.

As much as I hate that this is where my hopes are, I do hope that Powershell gets to a point where you can write single C# files and run them.

D language rdmd wrapper allows to compile-and-execute directly [1].

Together with intuitive function calling facility using Uniform Function Call Syntax or UFCS you can easily has natively compiled scripting environment [2],[3].

This site is horrible. Every comment here is trying their hardest to systematically dismantle this library out of existence through the use of nihilistic mind-games about what "shell scripting" "really" "is". All because they don't like a programming language that much.

You can write executable “scripts” in C by JIT compiling them with the shebang.

Tcc has the `-run` flag for easily doing this with a normal-ish shebang.

With a nasty polyglot preamble of C and bash at the top of your file, you can do it with any compiler.

LLMs are pretty good at using the standard utilities.

That, combined with reading the man pages if it doesn’t work first try has been really effective for me.
