If you are already in the terminal mode, there is 2 commands to do the job without using nautilus

To create the directory (for me is for HelveticaNeue)

sudo mkdir /usr/share/fonts/HelveticaNeue

And copy

sudo cp *.ttf /usr/share/fonts/HelveticaNeue/

bye (i’ll post on my wiki the tips -in french-, thanks)

Thank you, that worked perfectly, was sent a dfont by designer and need it in ttf

Thank you for this – it’s precisely what I was looking for.
