Now, there is only one function I modify when it comes to the appearance of
fish when I’m the one using it: I simply “delete” the =fish_greeting=
function.
fish when I’m the one using it: the ~fish_greeting~ function. I use it to give
me an overview of my computer’s status, including its hostname, uptime, disks
usage, ram usage, swap usage, and networking.
