Scrubbing through the video, this hurts my soul

echo $(echo $STRING | sed 's/World/Bash/')

For variables bash has PE forms:

echo ${STRING/World/Bash}

I miss these too much when I try Fish.

I wish that string command and also their math command were just general-purpose utilities pre-installed on all systems.

Tried to script something with sed the other day and was so confused why my regexes weren't matching, until we realized you need to pass --regexp-extended to get modern-day regex.

And then I later tried to calculate an average, which bc decided to round down, because it was presumably doing integer math. I actually ended up running python -c "print($total / $count)", because I could not be arsed to work out, if there was some flag to make bc work properly.

I'm fine with these tools continuing to exist for legacy purposes, but I would like a modern replacement just about now.

But I am using Fish. It's like you don't even know me!

I use Nushell, yes, I know I'm insane.
