export : Pass (export) the value of one or more shell variables, giving global meaning to the variables (which are local by default). If no variables are given, export lists the variables exported by the current shell.

set : With no arguments, set prints the values of all variables known to the current shell.

set & export are built-in cmd of bash.

env : pls man env..
