Alternatively referred to as caps and capital, uppercase (UC) is a typeface of larger characters. For example, a, b, and c is lowercase and A, B, and C is uppercase. Pressing the caps lock key will change between upper and lowercase characters or pressing the shift key while pressing a letter will make that letter capitalized.
Tip: It is bad etiquette to have everything you type in ALL UPPERCASE CHARACTERS. When reading anything that is typed in all caps most readers assume you are yelling or just find the text hard to read.
Using the uc command
my $example = "hello world";
$example = ucfirst($example);
$example = uc($example);
In the above example, the $example variable is first set as all lowercase. The second line uppercases the first character making the text "Hello World", and finally the third line uppercases the whole string making the text "HELLO WORLD".
