The most useful bash command of all: sudo apt-get -y install zsh; chsh -s zsh; exec zsh ;)

I kid, I kid! I actually like bash a lot. I really prefer it for scripting. Arrays are extremely useful but not specified in posix. Bash is pretty ubiquitous though.

I'm also curious if there are any bash partisans who prefer it over zsh and for what reasons.

I actually prefer fish, but I want to learn more bash because is is ubiquitous and a lot of bash stuff also works in fish.

You may also like NuShell. It's been designed from the ground up to be an intuitive and convenient shell language.

Wait, the other shells were designed to be obtuse and inconvenient? /s

Haha whoops, didn't want to imply that. I meant to say that it's intuitive for me, who finds bash syntax cryptic.

Can you tell me how to run a command and ignore an alias in NuShell? I don't really use nu but when i tried to write something in it, this was something that eluded me

Oh, if you want to avoid running a built in command like ls or cp and want to run the actual thing in /usr/bin, you prefix it with a ^, so eg ^cp -p.

Interesting. What does the ^ do in this situation?

And I just want to not respect an alias, so falls back to either builtin or path.

In zsh or bash I can prefix the command with the word command, or a backslash (directly before the command)

Fish is great! I used it for a while a long time ago but I ended up stopping because a few tools expected your shell to be set to something posix compatible. I wonder if the support is better now, I should give it a shot

I'm a serious bash scripter, I mean I do it both at work and as a hobby. And zsh arrays are better. Like you can use negative indecees and stuff. I have only written shell functions in zsh (my primary shell), and not thousands of lines of scripts like I have for bash. But if zsh had as good documentation and language servers I'd probably do many scripts in zsh instead. But I can't say for certain, as I am not as sure about performance in some situations and stuff.

Why don't I use posix shell if I care about performance? Because they are only faster in very simple scripts,
