fish_greeting - display a welcome message in interactive shells
function fish_greeting
...
end
When an interactive fish starts, it executes fish_greeting and displays its
output.
The default fish_greeting is a function that prints a variable of
the same name ($fish_greeting), so you can also just change that if
you just want to change the text.
While you could also just put echo calls into config.fish,
fish_greeting takes care of only being used in interactive shells, so it
won't be used e.g. with scp (which executes a shell), which prevents
some errors.
A simple greeting:
function fish_greeting
echo Hello friend!
echo The time is (set_color yellow; date +%T; set_color normal) and this machine is called $hostname
