Find and replace in file and overwrite file doesn't work, it empties the file

Question

I would like to run a find and replace on an HTML file through the command line.

My command looks something like this:

sed -e s/STRING_TO_REPLACE/STR

You can use Vim in Ex mode:

ex -sc '%s/STRING_TO_REPLACE/STRING_TO_REPLACE_IT/g|x' index.html

1. % select all lines

2. x save and close
