There is any way to transfer a child linux process to another process?

Question

If i have an zsh terminal with a child process in it, there is any way to transfer this process to another zsh session?

Example: I have a tmux session with two panels, two zsh process and a htop process on the first session, there is some way to pass this process to the second zsh session?

This image can illustrate the situation:

I've tried ctrl+z to send the process to background and fg %1 on other session but this doesn't work, apparently because the background processing is managed by the zsh session I think...

Answer 1

It's not possible in common case: child process belong to parent. But you can use screen or something like this to share commands output between sessions.
