Well:
- To change a directory you use
cd
so the command iscd /home/osmc
~
actually is equal to the users home directory so in your case it is/home/osmc
- While generally
dir
is a bit of a strange command on linux (on linux you usels
) it did the job and showed you the content of the directory and as you can see it seems you haven’t downloaded the file.
Maybe you want to read up some linux basics if you struggle with the given instructions.
