Export Variables in Bash

[ Thanks to Andrew Weber for this link. ]

"You may need to export variables in some circumstances in order to use them in the child process. The export command places the variable in the environment. The environment, which is the list of name-value pairs like PATH, is inherited from the parent process. The export command allows the child process to modify the environment of the child environment only.

"Locality of Variables

"Variables are local to the process where they were declared. See Declaring Variables for more context that helps define this blog post.

"The export command with the "-p" option will show the current variables of the environment."
