Explanation

You can use the tr command to convert all lowercase letters of a text file to uppercase. The tr command is used to translate, squeeze, and/or delete characters from standard input, writing to standard output. If you want to change all lowercase letters to uppercase, you will use the tr [a-z] [A-Z] command. commands cannot translate the text from one form to another.
