How to define an alias in fish shell?

Question

I would like to define some aliases in fish. Apparently it should be possible to define them in

~/.config/fish/functions

but they don\'t g

Answer 1

Just use alias. Here's a basic example:

# Define alias in shell
alias rmi "rm -i"

# Define alias in config file
alias rmi="rm -i"

# This is equivalent to entering the following function:
function rmi
    rm -i $argv
end

# Then, to save it across terminal sessions:
funcsave rmi

This last command creates the file ~/.config/fish/functions/rmi.fish.
