How to show content of a function in fish?

In fishshell, I can create and save a function very easy, like: 

function aaa
   echo hello
end

funcsave aaa

But how to view the body of the function aaa from command line easily? Is there any way other than:

echo ~/.config/fish/functions/aaa.fish
Solution

  • invoke functions aaa on command line

    username@MacBook-Pro ~> functions aaa
function aaa
    echo hello
end
username@MacBook-Pro ~>

    Some more uses of functions command

    functions -n
# Displays a list of currently-defined functions

functions -c foo bar
# Copies the 'foo' function to a new function called 'bar'

functions -e bar
# Erases the function `bar`
