case string1 in

string1 is compared to str1 and str2. If one of these strings matches string1, the commands up

until the double semicolon (; ;) are executed. If neither str1 nor str2 matches string1, the

commands associated with the asterisk are executed. This is the default case condition because

the asterisk matches all strings.

item in the list, until the last one is reached.
