How to run multiple command lines at once with nodemon in Ubuntu?

Question

linux

Good afternoon.
How to run multiple command lines at once with nodemon in Ubuntu?
I do the following in file.sh:
nodemon MicroService/User/src/user.js
How can I run several terminals (command lines) from this file at once and in each one to start nodemon with the nodejs microservice?
This option is not suitable:

nodemon MicroService/User/src/user.js & nodemon MicroService/Shop/src/shop.js

Since they all run in the same terminal.

This is what I'm trying to do to run all the microservices at once, maybe it's time for me to learn Docker or something like that?

Answer 1

Use tmux or screen.

Answer 2

run several terminals (command lines) at once - gnu screen
