Here’s ChatGPT’s response:
The set -ex command in a shell script (like your start.sh) has two parts:
-
set -e: Tells the shell to exit immediately if a command exits with a non-zero status. It ensures that if an error occurs during any step of your script, the script halts execution at that point to prevent further errors or unintended effects. -
set -x: Makes the shell print each command before executing it. This is useful for debugging, as it shows you exactly what is being executed, helping you understand the flow of the script or catch mistakes in the commands.
So, set -ex in your start.sh script is used to make the script exit on any error while also printing out each command before it is executed, providing a clear and detailed execution trace.
