capitalize - change case of text
capitalize is a filter that changes the case of text sent through it.
It reads text from stdin and writes the result to stdout.
Please note that capitalize is intended mainly to be run from XView’s
text menu. It is used in the default text_extras_menu.
-u Convert all characters to upper case.
-l Convert all characters to lower case.
-c Convert the first letter of words to upper case.
