Converting VBScript's UCase Function
Definition: Returns a string that has been converted to uppercase.
UCase
Sometimes bigger truly is better, which is one reason you might want to convert all the characters in a string to their uppercase equivalent. How do you pull off such a feat in Windows PowerShell? That’s easy: you just call the ToUpper() method. For example, these two commands assign the letters of the alphabet to the variable $a, then use the ToUpper() method to convert each of those letters to uppercase:
$a = "abcdefghijklmnopqrstuvwxyz"
$a = $a.ToUpper()
When you run this command and then echo back the value of $a you should get the following:
ABCDEFGHIJKLMNOPQRSTUVWXYZ
