Saving Changes

Learn how to save changes in a file after making changes with the sed command.

We'll cover the following

Redirection

In the previous lesson, we learned how to edit text using sed. Now, we’ll learn how to save those changes. To keep the changes we’ve made with sed, we have two options. Our first option is to redirect the output to a new file using redirection.

Let’s run the terminal below to execute the following command to transform all instances of very to really and save the results to the file new_document.md:

cat << 'EOF' > document.md
This is *very* important text with *very* important words.

* These words are not important.
* Neither are these.

You can *always* tell very important text because it's in italics. 
EOF
sed -e 's/very/really/g' document.md > new_document.md 
cat new_document.md

Run the complete code on the terminal below for practice.
