Couldn't agree more. I did the same. Big improvement in performance and I have a better idea of how to customize as per my preference.
I was also worried about random code getting downloaded to my machine and getting executed.

Thanks for showing us how to test that. My standard ohmyzsh takes 0.185 seconds.
~ time zsh -l -i -c 'echo "test"'I use powerline-shell in zshell, and was also extremely annoyed by the delay.
So, I decided to rewrite https://github.com/banga/powerline-shell in go, and the performance is amazing.
The latency went down from several seconds to 200µs (except when git is used, then it’s ~4ms), and it’s fast enough.
The repo is at https://github.com/justjanne/powerline-go. Here’s a small video showing just how different the latency is: https://s3.kuschku.de/public/2017-08-21_16-43-41.mp4. Disclaimer: Although the original was MIT, I licensed my rewrite under GPLv3.
Improving the latency of software is just such an amazing quality-of-life improvement, it was well worth those 10 hours of work.

Pretty sweet collection of zsh shortcuts and tips.
Who cares if it's old, if it's still relevant?
Is there something out there now that is better than zsh?

I cannot claim that it is better than zsh in every aspect yet, but it is getting there.

Super interesting! Totally worth a post in itself IMHO.

No one has yet implied that it's irrelevant because it's "old".
However, my view is that we are generally chronological beings at heart, and knowing the year that something was posted (if it wasn't the current year) is a useful to aid in determining whether we may have seen it before or whether it may be particularly relevant to our interests.

Fish is pretty sweet. The biggest annoyance IMHO is that you have to use env to set environment variables inline to execution.
My biggest issue with fish is that it has no way of letting me kludge the last command like bash does. I have muscle memory for bash shorthands like !$ For last word of the last command I executed or !! For the whole line.
It still catches me out with its sub shells too sometimes. ( () is equiv to $() in bash )
Also. No control+R
Otherwise I think it's a beautiful shell and I keep using it.

The fish philosophy is that instead of "!!" you can use the up arrow to bring up the last command from history and then edit it directly.
And the up arrow already does something similar to ctrl-R by default. No need to have a separate hotkey for that behavior.

What would control+R do for you that isn't just part of the fish autocompletion?

I don't think the env thing is that big of a problem with Fish. For me, the most annoying thing is that it doesn't interoperate well with programs that output POSIX shell strings that you are expected to eval. One particularly annoying example is pkg-config.
Agreed, this isn't that annoying; i largely have no issues with fish at all.
However, I particularly found it difficult to get working with nix, unfortunately.

I tried fish for a while some years ago, and left it when I noticed that its pipes were fake. Second command in a pipeline couldn't read any input until first command finished running. That made it useless for things like `strace ... | grep ...`. Trying it now, it seems they've fixed that.
I remember that I was interested in it for its multiline command formatting and history. Since then, though, I've learned that zsh also has support for multiline command history, and its vi keybindings support multiline editing for a single command. It's like every command line is a little multiline vi buffer. For this reason, I've chosen my prompt so that the command starts at the first column.

Been a fan of fish mostly for its typeahead autocompletion. I do miss that it doesn't have some of the Bash features others have mentioned, but it's a feature I haven't been able to replicate in other shells yet.
grml's zsh config is so good that I never wanted to change anything in it (it's default in Arch liveusb)

oh-my-zsh is really good. The only thing I needed to do was set DISABLE_UNTRACKED_FILES_DIRTY="false" which is a default that really makes no sense

I spent a few hours on this about a year back and went from over 2s to about 0.15s for a full run of an interactive login shell (`time zsh -l -i -c 'echo "test"'`). No functionality lost, at least none that I actually used and cared about.
Definitely one of the best quality of life improvements I've made to my setup in recent years.
