Answer 1

If using pipes and Python:

$ echo "HELLO WORLD" | python3 -c "import sys; print(sys.stdin.read().title())"
Hello World

For example:

$ lorem | python3 -c "import sys; print(sys.stdin.read().title())"
Officia Est Omnis Quia. Nihil Et Voluptatem Dolor Blanditiis Sit Harum. Dolore Minima Suscipit Quaerat. Soluta Autem Explicabo Saepe. Recusandae Molestias Et Et Est Impedit Consequuntur. Voluptatum Architecto Enim Nostrum Ut Corrupti Nobis.

You can also use things like strip() to remove spaces, or capitalize():

$ echo "  This iS mY USER ${USER}   " | python3 -c "import sys; print(sys.stdin.read().strip().lower().capitalize())"
