Trying this out myself, I noticed that it wasn't being run interactively. To make that work, you need to redirect the source directly into a
sh
process. Piped execution doesn't support interactivity.This PR updates to use process substitution syntax. As discussed in fish-shell/fish-shell#5181, fish (my preferred shell) uses a different syntax, so I added special instructions for that. I also removed instructions for
fetch
, because I thinkwget
andcurl
cover the vast majority of use cases.
