fetch pid of new process in tmux

[kal le]

Hi

I hope you are doing great! 

I'm trying to fetch the pid of a command that I execute within tmux.

So I'm in linux and starting a command like this

tmux new-window -n foo "sleep 10"

and now I want to fetch the pid of the "sleep 10" process.

The best solution I found (I can have multiple of the same process within tmux) is to

tmux list-panes -a -F "#{window_name} #{pane_pid}" | grep foo

Do you know a better way to do this?

Thanks and best wishes! /Karl

P=$(tmux new -dnfoo -PF '#{pane_id}' 'sleep 10')
tmux display -pt$P '#{pane_pid}'

Thanks NIcholas!

That is much better since it gets the exact pane id. :)

I used you arguments and got the pid directly.

tmux new -dn foo -PF '#{pane_pid}' 'sleep 10'

Best wishes! /Karl
