POSIX shell is the worst language ever invented, that is still in widespread use.
Its dialect bash is even worse.
Prove me wrong.

its only purpose is to call commands and at most do a few basic things on a whim

Picrel. It's fast to prototype and test, it's globally accepted, it's understood by everyone. It's interoperable with other sysyems and doesen't require any setup

If you've actually seen any shell scripts, you would know that is false. More of your code is about working around bugs in shells than doing what your script is supposed to do.

That perfectly describes C and Unix including its shells.

I see where you're confused but Unix shell uses "C" to mean the standard C locale, not the C programming language. It's part of a shell script.
>That perfectly describes C and Unix including its shells.
It's funny because it's true.
I like it so it can't be that bad.
I agree, this is why I use a good language (Lua) for all my shell scripting stuff
[code=Lua]
ls '/bin' : grep(filter) : wc '-l'
[/code]
How does Lua perform against POSIX? I assume it's much faster than Python.
Lua can be much faster Python or Shell. Luajit proves that it can achieve C speeds for some tasks.
But its standard lib is too minimal and barely covers what standard C (without POSIX) can do. You might be able to write a good library for shell tasks, but that applies to any language.
You can use luaposix for all the posix functions. Luarocks has so many libraies for anything you need

With LuaJIT its much much much faster. Even base Lua its faster but LuaJIT is amazingly fast
Wow such subtle trolling.
We need the Wayland of bash.
im not trolling, I fricking love lua so much its unreal. I try and write everything in lua
Even though I wrote some Lua code and added Lua bindings to 2 or 3 programs, I'm unfamiliar with the : operator. What does it do? Your example looked made up.
In lua, the `:` operator passes in the table as its first argument, so like this
local my_table = {}
function my_table:some_function()
print(self)
end
my_table:some_function() -- will print table: <some address>
my_table.some_function("hello") -- will print hello
its best matched up with when you are doing OOP
Oh shit, it's the method syntax. I just forgot.
that would be powershell

So does this reimplement the tools, or just call them? It still misses one of two important properties:
>it's all integrated, like you can do "ls -h" or "man ls" to get help without needing anything else
>it can be implemented in any programming language without needing adaptation wrappers

Right, bash was made by a black man! Refuse bash!
zsh is where its at.
