Hello!

If it is possible, the description is in the Arch Wiki (Fish Page) or it is in here (The Fish Manual).

Regards
Martin

Re: [SOLVED]how to change the error message in fish shell

This is where it's defined: https://github.com/fish-shell/fish-shel … .fish#L176

There's even a conditional for pkgfile, a utility on Arch that can search for packages that provide the missing command.

If that's not what you're looking for, perhaps you can override the built in handler. I don't use fish, so I don't know if that's possible or not.

Re: [SOLVED]how to change the error message in fish shell

thanks that helped me figure it out
I replaced:

if test -f /etc/SuSE-release; and type -q -p command-not-found
			function __fish_command_not_found_handler --on-event fish_command_not_found
				/usr/bin/command-not-found $argv[1]
			end

with

if test -f /etc/arch-release
			function __fish_command_not_found_handler --on-event fish_command_not_found
				/usr/bin/betty $argv[1]
			end

i used the command betty to call the betty digital assistant so when ever i type something like:

download http://www.mysite.com/something.tar.gz to something.tar.gz

or

find me all files that contain california

in my terminal it would give me something useful without having to prefix every command with betty

EDIT: I had to install fish-git for this to work
