votdev- I have been using Linux variants for the past two years, mostly on the Raspberry Pi. I installed Debian 9 on a spare PC and am learning a lot from ths forum and your posts.
You make installing OMV4 on Deb9 look simple in your post: "Install OMV4 on Debian 9 (Stretch)".
However, I am confused by the construct of "cat <<EOF >> /etc/apt/sources.list.d/openmediavault.list". What does <<EOF>> do?
Also, I've never seen the export command, and there's no man pages for it. What are these export lines doing?
I never do anything without some understanding what I am doing, so an explanation of the process in your post would be greatly appreciated.
Many thanks,
Steve Mann
