CLI Variables

Assignment and Dereferencing
To assign a value to an environment variable you simply type the variable name, '=', then the value. For example, FOO=Rob BAR=Love

To get the value of the variable (i.e. dereference) you place a '$' before the variable name.

#Rob
 * 1) echo $FOO
 * 1) echo $BAR
 * 2) Love

Commands
env = Shows you the environment variables that are currently defined. echo = Displays a line of text.
