Condition for checking if bash script has been sourced
Suppose you have written a bash script for a complex manual activity and got a lot of praise from your team members... however, this script only runs as expected if it is sourced. Is there a check that can be present in the script which will throw an error if the script is not being sourced and being executed directly.
