Pause script until command in other script is executed [Bash]

Question

In script a I tell script b to execute a certain command. Is there a way to pause script a until script b is done executing? I don't want to use sleep, because every run of the script can be different.

Use:

wait <pid>

This will cause script A to wait for B to complete before continuing.

How can I catch the pid of script B in script A?

Once you have spawned the process, "echo $!" will return the pid
