echo '
alias -s apt 'pac'
' >> ~/.config/fish/config.fish
echo '
function sudo
    if functions -q $argv[1]
        set cmd "command sudo fish -c \"$argv\""
        eval $cmd
    else
        command sudo $argv
    end
end
' > ~/.config/fish/functions/sudo.fish

# FOR ZSH
cat >> ~/.zshrc <<EOF
alias apt='pac'
alias sudo='sudo '
EOF
