Each word on a separate line

Question

I have a sentence like

This is for example

I want to write this to a file such that each word in this sentence is written to a s

Answer 1

A couple ways to go about it, choose your favorite!

echo "This is for example" | tr ' ' '\n' > example.txt

or simply do this to avoid using echo unnecessarily:

tr ' ' '\n' <<< "This is for example" > example.txt

The <<< notation is used with a herestring

Or, use sed instead of tr:

sed "s/ /\n/g" <<< "This is for example" > example.txt
