How do I flush output to a zenity progress bar in fish shell

In bash I can run the following to get a progress bar for long running processes

for i in $(seq 90 100); do 
  echo $i; 
  sleep 1; 
done | zenity --progress

However if I attempt the same thing in fish shell, the loop blocks and doesn't flush output down to zenity until it's finished:

for i in (seq 90 100)
  echo $i
  sleep 1
end | zenity --progress

How would I create a similar progress box in fish shell?

Solution

  • Fish currently buffers all output belonging to functions and blocks, so:

    You don't.
