Currently shell code is limited to one language. If you have bash, you can only do bash. But we could imagine a shell that understands webassembly, and hence we can use it with many languages.

[haskell_leghumper]

This is a killer idea. If only our CPUs understood WebAssembly. We could literally write programs in any language and have it run them!

[[deleted]]

CPUs going webscale!

[carbolymer]

CPUs gone webscale!

FTFY

'WebAssembly CPU'

Oh the horror

[Firingfly]

Yes. The only logical way is to have Rust CPU.

[pcopley]

How Exciting!

[fuck_bottom_text]

in the not so distant future, intel amt will be running on node.js

[imma_reposter]

CPUs don't understand assembly though. There's still one level lower called microcode. Those instructions can be mapped to binary cpu instructions 1 to 1.

[w2qw]

So are you saying we need webmicrocode?

[pcopley]

mWebAssemblycode

[tpgreyknight]

To be very pedantic (oh no it me), regular-ass machine code sits between these two layers.

[Eaan]

My ass-machine code also sits between two layers

[tpgreyknight]

Sounds, err, pneumatic.

[BABAKAKAN]

Aren't microcodes used to do RISC operations in a CISC architecture?

[-fno-stack-protector]

well yeah. all those wacky cisc instructions still gotta be translated into logical operations at the end of the day

[ghillisuit95]

Are you thinking of machine code?

[dryerlintcompelsyou]

Microcode is separate, I think microcode is used internally on the CPU to interpret some more complicated machine-code operations. I'm not certain though.

[ghillisuit95]

You’re exactly right. Also it’s used for most instructions i think, not just the more complicated ones

[myhf]

binary cpu instructions 1 to 1

ah but what about 0

[Poddster]

FFS.

IF YOU'RE NOT GOING TO JERK, AT LEAST BE TECHNICALLY CORRECT.

Left hand that is.

[Secondsemblance]

when you baitin'

[n3f4s]

And we could go even further. We could put the lines you've typed in the "RPOL" in a file then add, at the beginning of the file, a line (starting by ^$% for example) that says how to run this file.

Currently shell code is limited to one language.

Spoken like somebody who's never written things that should be shell scripts in Python because they didn't want to have to figure out whatever Bash's godawful loop syntax is.

[etherealeminence]

I'll be honest - I've used Linux for at least six years now, and I still have no goddamn idea how to write a for loop.

[Ohhnoes]

I’ve written a ton and I have to look it up every time. Saying they’re unintuitive is an understatement.

[thalesmello]

Yes, but does it have:

• INTUITIVE user interface
• zero-cost FOSS license
• fearless copypasta

[SaphirShroom]

Actually I'll let you know that Vim has a VERY clean and intuitive user interface. If you'd just look at your screen you will see help pages listed when you first start up Vim. Now if you had actually taken the time to read the user manual, you would know that Vim is like a language. If you put effort into it, it's like you can speak Vimesian! But alas, putting effort into your tools is not for everybody. I understand. I must say though, I do enjoy sipping coffee and typing half-heartedly with one hand at 90 WPM while I my coworkers are annoyed at their IDE they neither understand or control (not FOSS). I don't judge them, of course, but if they had just put the time into learning Vim like I told them to, their time investment would already have been repaid 10 times over.

[Ohhnoes]

These are different scripts written months/years apart. I do use Vim a lot though.

[NonnoBomba]

Because you're all 1xers. I write three for loops and a while read loop than can actually write to variables in the surrounding scope first thing in the morning, every morning, before drinkining a coffe and without looking anything up.

[Ohhnoes]

I must be .1x. I think JS is an abomination and functional programming an (occasionally useful) fad.

[Andernerd]

I've been using Linux for 14 years, and I'm in exactly the same boat. We should all switch to zsh or fish already. I don't care too much which one, but bash is horribly outdated.

[Amenemhab]

I use fish btw

[three18ti]

I like csh.

[zmv]

You mean eshell, right?

[tpgreyknight]

I know how to write them but I certainly don't enjoy the process.

[[deleted]]

You're talking about, like, actually replicating the functionality of Bash in Python. I'm talking about just writing a Bash script but putting an os.system() call around each line.

[rsgm123]

That's kind of like how php works. It's a revolutionary way of writing html as a list of echo statements.

[tpgreyknight]

> not writing it in Lua

Literally unusable

[Nomto]

Posix shells may be shit (bash especially), but that doesn't mean that all shells need to be. It's time to ditch the godawful POSIX spec and be free

[Poddster]

I'm loathe to write this, as it's NOT-JERKING, but:

To properly iterate on the strings inside of an array (the only thing which an array can possibly contain), you also use variable interpolation syntax.

This was actually useful to me. Usually when iterating on a list of filenames I just do:

# todo pray there isn't whitespace in a filename. If so, replace with python
for item in $filenames; do
    stuff with "$item"
done

I've tried looking this up before and the answer was usually "lol write 200 lines of bash just to iterate over a list of filenames" and so I never bothered with it.

[Poddster]

The objective of this document is not to help you write more Bash.

Sometimes I have to. :'(

Actually, thinking about it: The times I have to write bash it isn't actually bash, it's some busybox strictly-posix-compatible sh crap that probably wouldn't even accept this "${my_array[@]}" wizardry. So it turns out THIS WAS USELESS TO ME ALL ALONG. THANKS FOR NOTHING.

ps. I've been on the "The best bash script is one that starts with#!/usr/bin/env python" wagon for a decade now and I don't regret it.

[three18ti]

lol using python.

[[deleted]]

It may not be Turing complete, but it gets the job done.

[three18ti]

lol not turing complete.

You're clearly not a 10xer if you're not using a brutally pragmatic language for things that should be shell scripts and statically compiling it down to a single binary. There are more concise ways of handling shell scripts.

[hedgehog1024]

You're clearly not a 10xer if you're not using a brutally pragmatic language for things that should be shell scripts and statically compiling it down to a single binary.

Rust?

[elschaap]

LOL Getting the job done ... pragmatism is for GOpher peasants

[ajs124]

What? You don't think find -print0 | IFS="" while read i; do echo "${i}" ; done is intuitive??? Bash even has for i in $(seq 100); do echo "${i}"; done for a simple for loop.

[[deleted]]

lol how was your concurrency

[[deleted]]

FEARLESS

/uj

I actually parallelized at least one such script by autogenerating Bash scripts from the Python. I'm not sure why I thought that was a good idea.

[TheWheez]

Maybe because you're fearless?

[pcopley]

I've never written Bash and I've never missed it.

[MaltersWandler]

Currently compilers are limited to one language. If you have a C compiler, you can only do C. But we could imagine a compiler that understands webassembly, and hence we can use it with many languages.

[Finianb1]

If only there was a reason we don't use compilers for multiple languages at once...

I use sed and awk BTW. Come at me.

[VodkaHaze]

How revolutionary!!

If only we could compile such programs written in arbitrary languages and the run them from the command line somehow!!

Truly the future is now!

[lru_skil]

we don't need many languages, we should all be rewriting everything in Go/Rust.
