tr (translate)¶
The tr (translate) command allows you to translate a set of characters into another set of characters. Let's try an example of translating all lower case characters to uppercase characters.
$ tr a-z A-Z hello HELLO
As you can see we made the ranges of a-z into A-Z and all text we type that is lowercase gets uppercased.
