I wrote the following script:

#! /bin/bash
source service supervisor stop
source service supervisor start
source service nginx restart

usechmod 755After giving permission, I ran it. Returned:
stopping supervisor...
Then change the script to:

#! /bin/bash
source service supervisor stop &&
source service supervisor start &&
source service nginx restart 

Run again or return:

stopping supervisor...

Wait for me to use any of the following commands in the terminal:

source service supervisor start
source service supervisor status

The same is true of nginx’s commands. Before flashing back, you will be prompted:

basename invalid option -- 'b'
Try 'basename --help' for more information.

I don’t know much about Linux. After reading the tutorial, I wrote the script. This time, I know it’s wrong. Please give me some advice.
