Can't get pid after executing command

I need to execute node and firefox in that order. The node process needs to remain in the background until I close firefox manually.

I've tried this command:

node & nodePID=$! && firefox && pkill $nodePID

but $nodePID seems to return pid of firefox instead of node. How would I fix this?

Note that I can't just pkill node since I might have different node processes running at the same time.

Consider using kill $nodePID instead of pkill ....

Also you want NOT to chain the commands with '&&'. For example, if firefox fail to launch, you still probably want to cleanup the node process. The assignment (nodePID=...) will never fail.

node &
nodePID=$!
firefox
kill $nodePID
