Answer 1

If you want to run multiple commands sequentially, there is a really simple method that works everywhere: Creating a file! The benefit of this method is that it's clean and simple.

First, create your file with a name, e.g. commands.sh. Then, put your commands there. Here's is a sample:

commands.sh:

#!/system/bin/sh

sleep 3;
sleep 2;

OK, now we're in the last step. To run commands in the background (sequentially), just run:

$ sh commands.sh &

Answer 2

to run multiple background command you need to add & end of each command. ex: (command1 &) && (command2 &) && (command3 &)
