Begin at the UNIX Command Line, already in your public_html directory. Open your previously generated HTML File.
Modify it to look like:
<HEAD><TITLE>This is my Second HTML Page!</TITLE></HEAD>
<H1>This HTML stuff is very very hard!</H1>
Save the file (type "s", then hit Enter to keep the name myfile1.html) and Exit pico.
Since we updated an old file, rather than creating a new one, it already has the proper Permissions. The Web address is the same as well.
