How do I make this an alias?

[KDen]

I installed bat and gave it a try. Here’s some info that might help.
I got the same result. Worked directly from the command line but permission denied as an alias.

However, I tried it in Fish Shell and it works. Aliases in Fish Shell are actually functions. So that got me looking.
From my understanding zsh and bash alias are a bit more limiting than other shells

Aliases will only be replaced at the beginning of the command prompt. Also additional arguments will be appended after the replacement.If you need to insert additional arguments somewhere in the replacement, you cannot achieve that with aliases.

So you need to create a function instead of an alias

function last2() {
	bat $(find ~/.updates/  -print | tail -n2)
}
