Bash and zsh have basically the same thing. It's meant to give you a nice error message like "foo is missing. You can install it with 'apt install foo123'" See: - https://zsh.sourceforge.io/Doc/Release/Command-Execution.html#Command-Execution https://zsh.sourceforge.io/Doc/Release/Command-Execution.htm... for zsh - https://www.gnu.org/software/bash/manual/bash.html#Command-Search-and-Execution https://www.gnu.org/software/bash/manual/bash.html#Command-S... for bash You could make it run arbitrary things, but then you're quite clearly misusing it and e.g. there's no way to make it return a different status, fish will still view the command as failed.
