I'm trying to install Fish Shell on an updated Amazon Linux machine, I keep getting the error:
Requires: hostname
I tried both repositories offered on the Fish Shell website for CentOS 6 and 7, delete both before trying the other. Nettools is installed, it's a standard Amazon Linux install, so it has all the basics. If anyone can help it would be appreciated! Thanks in advance!
See https://github.com/fish-shell/fish-shell/issues/2062
Both a strength and weakness of fish is that it depends more heavily on external commands than shells like bash or zsh. You need to explicitly install whatever package provides the hostname command for your OS. In the future we intend to make the dependency implicit when installing fish.
