beginners handbook for NextCloudPi?

Maybe look here for starters with NextCloud?

To learn the Pi try

and/or

It's hard to recommend books on Linux (or anything else) sight unseen. Maybe go to a local bookstore and see what they have that suits you. Ideally you'' find a book on the Raspberry Pi version of Linux... Raspbian.

Thank you very much for the links.

But. of course, additional links are highly appreciated,especially links to online documentations, I have a lot of time now.

That's no more possible here in Germany :)

We have an almost completely shut down here due to Corona virus. All shops except groceries, pharmacies, gas stations, and building supplies stores are closed, all public meeting places like theatres, museums, opera, cinema, kindergardens, universities (as a special form of kindergarden), schools , and so on, too. Local traffic systems are running in holiday or sunday mode. Frankfurt airport closed one runway to have place for parking airliners. People are told to work at home, if possible, and not to stay together in groups, and we expect to get a ban of walking outside soon.

It's almost like in the casino - rien ne va plus. Almost nothing.

OK, here you go: these are all general Linux recommendations because I know nothing about NextCloudPi

Seeing that you already know one operating system well,

"Linux in a Nutshell" may be useful since it assumes that you already understand another operating system. There seems to be a German edition too. It does assume you're happt using a command line - unsurprising since very few of the standard programs have graphical user interfaces. Its fairly pricing, so you could also look for a used copy of either it or "UNIX in a nutshell" because Linux is really a clean-room reimplementation of UNIX and many of the utility programs are the same. "Linux for Dummies" covers much the same material, but with more explanation and without expecting you to know much about other operating systems.

Freebies ======== Bookmark and visit:

This is a relevant site because Raspbian is Debian Linux adapted to run on a RaspberryPi

Also bookmark:

This covers virtually everything you could want to know about Raspbian but were afraid to ask. It isn't an easy read because it can be technical and there's a lot of it, but it is well laid out.

And finally:

System D is the support system the boots Linux and manages its operation as well as major servers running under it. As you are installing such a major system, this link, which is well laid out and fairly easy to follow, may save yo sal lot on time and trouble if yoy run into problems. ==============

Get know how the manpage system works. manpages document all the programs etc installed on your RaspberryPi. The command:

man less

tells you how to use the 'less' program, which is used to search through and read text files. The command 'apropos' is used to search through the manpage library to find the utility program you need to do something:

apropos file

This command lists the names of all programs that work with files. You scan this list to find one that does what you want and then use the 'man' command to read how to use it. There are many more utility commands that you're used to under Windows because the UNIX/Linux way is to write utility programs that only do one specific thing, but do it extremely well, so:

cp - copies file(s) to create copy(s) with a different name or in a different directory mv - moves renames files or moves them to a different directories rm - removes (deletes) file(s).

I hope this helps.

I wish I had this book when I started! Yes, it's biassed strongly towards Amateur Radio, but the Linux and RPi introduction makes it well worth getting:

Interesting the members / non-members prices because the publishing costs to the RSGB will be no more than a couple of squids so they're really screwing their own members!
