Synatx: *STRING*
To determine if a string has a substring, use an asterisk “*”and surround the substring with it. The purpose of the symbol is to match all the characters.
If you take a look at the example script below, the word “internet” can be found in the string variable strval=”Microsoft Internet Explorer”. This will give you a result of partially match in the firs if. However, by using the word “internet“only, you will get false as a return for the second if.
