Why does the fish shell need to start a daemon process

fish

I just started playing with the fish shell, and I really like is so far.
However, I can't figure out what the purpose of fishd is.

So, why does fish need to start up a daemon process?

What is the daemon process used for?

Best Answer

From fishd man page:

The fishd daemon is used to load, save and distribute universal variable information. fish automatically connects to fishd via a socket on startup. If no instance of fishd is running, fish spawns a new fishd instance. fishd will create a socket in /tmp, and wait for incoming connections from universal variable clients, such as fish, When no clients are connected, fishd will automatically shut down.

Shell – Get default ubuntu motd in fish shell

Put this in your ~/.config/fish/config.fish:

function fish_greeting
  status --is-login
  if [ $status != 0 ] 
    cat /run/motd.dynamic
  end 
end

This will make sure that you don't get the double motd when logging in remotely.

Adding pass completion to fish shell

The second option listed (~/.config/fish/completions/pass.fish) is the preferred approach. The third should also work.

I tried the following:

Put the file at ~/.config/fish/completions/pass.fish
Type pass followed by a space
Hit tab

And I see completions from that file.

It's possible that fish is looking somewhere else. Try echo $fish_complete_path and verify that it includes ~/.config/fish/completions/ . If it does not, you can put back the defaults by erasing it and starting a new session: set -e fish_complete_path.
