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 get auto loaded when I restart the shell. Any ideas?

Answer 1

Just use alias. Here’s a basic example:

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

# Define alias in config file ( `~/.config/fish/config.fish` )
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

# or, since Fish 3.0, define and save all at once:
alias --save rmi="rm -i"

The command funcsave creates the file ~/.config/fish/functions/rmi.fish. This is handled automatically when using the newer alias --save syntax.

More info about Fish aliases can be found in the official manual.
