How to list the variables that are used in a script?
Is there a command that can list the variables that I am using in a script? I mean the variables that I created in the script not the environment or local variables. For example if I have a script that has the following var's like : name=Alex, age=20, postal_code=12345, how can I list them all @ once WITHOUT using echo $name, $age and so on. Imagine I have a lot of variables and i can't echo them all. Thanks
