In Linux (Shell), there are two types of variable:
(1) System variables - Created and maintained by Linux itself. This type of variable defined in CAPITAL LETTERS.
(2) User defined variables (UDV) - Created and maintained by the user. This type of variable defined in lower letters.

Shell variables
var refers to the name, $var to the value - t = 100 #Sets var t to value 100 - echo ”\$t = $t” #will print: $t = 100
Remove a variable with unset var
Names begin with alpha characters and include alpha, numeric, or underscore
