​Thank you both for your explanations. I'm trying to understand the
difference between the script execution method using the 'exec'​

​command and using one of the standard methods, but the following
explanation is unclear to me:

​
"exec is not truly a script execution method. It does not create a subshell
but instead replaces the current shell with an *executable image
environment* to run the script."
