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.

Answer 2

If you add an abbr instead of an alias you'll get better auto-complete. In fish abbr more closely matches the behavior of a bash alias.

abbr -a gco git checkout

Will -add a new abbreviation gco that expands to git checkout.

Here's a video demo of the resulting auto-complete features

Answer 3

make a function in ~/.config/fish/functions called mkalias.fish and put this in

function mkalias --argument key value
  echo alias $key=$value
  alias $key=$value
  funcsave $key
end

and this will create aliases automatically.

Answer 4

fish starts by executing commands in ~/.config/fish/config.fish. You can create it if it does not exist:

vim ~/.config/fish/config.fish

and save it with :wq

step1. make configuration file (like .bashrc)

config.fish

step2. just write your alias like this;

alias rm="rm -i"

Answer 5

1. if there is not config.fish in ~/.config/fish/, make it.
2. there you can write your function .function name; command; end

Answer 6

I found the prior answers and comments to be needlessly incomplete and/or confusing. The minimum that I needed to do was:

1. Create ~/.config/fish/config.fish. This file can optionally be a softlink.
2. Add to it the line alias myalias echo foo bar.
3. Restart fish. To confirm the definition, try type myalias. Try the alias.
