Title: Terminal trick - progress indicator in the task manager

KDE's konsole has a neat hidden trick. You can set progress indicator in task manager's entry for the terminal that will be affected by the tab where you do it.

Using this escape sequence:

printf "\x1b]9;4;1;70\a"

Sets the progress to 70% for example.

To reset:

printf "\x1b]9;4;0\a"

I discovered it with neovim using it to show progress of updating plugins with vim.pack

The feature is called OSC 9;4 if you want to get more info about it.

That's actually pretty cool. Is that just Konsole or is this implemented by others as well?

Need to remember it. Let's test the bookmark feature for the first time!

Really neat!

Seems to work in vte terminals (gnome-terminal & ptyxis), but it was a little bit fiddly. I had to use
echo -ne "\e]9;4;1;75\e\\"

State 3, the indeterminate/pulsing state doesn't seem to be implemented though.
