How to copy files from local computer to Yun with scp?
Try ~/Documents/index.html

The ~ represents the current user's home directory, so ~/Documents is the Documents folder for the current user.  It means you don't have to make sure you have spelled the user's home directory exactly right.

Other options are:


$HOME/Documents/index.html
Documents/index.html (if you are in your home directory)
cd ~/Documents then just use index.html


... the list goes on ...
