Sorry about post #11, I hit return and the unfinished post got uploaded by accident. [Mistakes can happen, see below].
I think you are getting lost because you do not know any basic bash
commands, and you do not know your way around the filesystem.
You are in a very dangerous situation:
- You are running as root (one tiny
typo and all your data can be gone!)
- You do not know what you are doing
- In a situation like this it is very very easy to make a complete mess of things, from which you cannot recover
If these databases and websites are valuable or important to you, I suggest you get a professional to help you, or have very
good backups and you are confident you know how to restore from them.
For example, if your USB drive holds all your website & database data, it would have been a very
good idea, when you mounted it, to mount it as "Read Only" - That way it is much more difficult to delete your data before it has been safely copied over.
I also fear you are about to run, at full speed, into a shedload of problems with UIDs, GIDs, ownerships and permissions.
Please, get help.
[Where did this system come from? I very much doubt you installed it. I mean this nicely, as perhaps the person who installed it can help you out].
