Using bash builtins and while loops to launch in a tab

[Strykar]

kitty is auto started on boot via XDG-autostart and opens a few tabs that run programs based on if certain services have started successfully. Till today, I just used sleep 60 to give the services enough time before starting my programs.

Today I tried while systemctl status livepeer; do journalctl --catalog --boot --follow --unit livepeer; done but that shows the output of the systemctl status command and does not execute the do journalctl when I try to invoke it via a session file like bash -c 'while systemctl status livepeer; do journalctl --catalog --boot --follow --unit livepeer; done'

What am I missing here?

I tried and it works fine.
Maybe you need systemctl is-active --quiet service-here.

# startup-session.conf
launch --allow-remote-control bash -c "printf waiting; while test ! -f /tmp/flag >/dev/null 2>&1; do printf .; sleep 1; done; kitty @ launch sh -c 'echo ready; exec bash -il'"

kitty --session ./path/to/startup-session.conf
touch /tmp/flag

@page-down Thank you! ❤️
launch bash -c 'while systemctl is-active --quiet livepeer; do livepeer_cli; done' works!

Any idea why it would fail when using systemctl status?

This is because the command will not exit.
You need systemctl status --lines=0 service-here .

If you want to keep the log displayed at startup, end the log viewer when service is up, and start the command line tool.
Then you need to write some more scripts.

Ah, perhaps --no-pager might make it exit too? Thanks, that helps!
