how to wait in shell script until a module is loaded?

Question

I am trying to write a shell script that should load a kernel module at first.

modprobe wlcore_spi

The next step should wait this process to be finished(an output on std "wlcore loaded") then move forward. But how can this waiting action be done? I tried:

modprobe wlcore_spi
wait
echo "hello world"

It seems it's not worked as I expected. I searched abt it and it seems the best should be find the pid then simply wait for it. Then I start this job then typed "ps aux", it seems it's not in the process? It seems it starts somehow another process and eventually gives back a signal when it's finished. How can I catch this?

Answer 1

You can use && option for your case.

modprobe wlcore_spi && echo "hello world"

So command B will be executed when commanded A exited successfully.
