Unix command line on PC using Ubuntu - unix

I am new to these forums and to using Ubuntu and linux and UNIX. I really need some help here. I hope I haven't shot myself in the foot already. I have been trying to complete a UNIX carpentry lesson on the internet for an assignment. I am learning the basics about UNIX. I am not using a Mac, I am using a PC that I did not configure in any way (maybe that's my problem). I am using windows 10 on a lenovo and trying to the command prompt on Ubuntu to find my desktop where a file called "data-shell" is located. The problem: IT IS NOT FINDING THE DESKTOP. Upon further inspection, I have been looking through the location of my desktop and "data-shell" file and found it in the Users location under a number 12094, which I am assuming is the serial number for the computer. I have NEVER fiddled with the software at all with this computer as it cost me a lot of money, but I really do not want to be stopped in the tracks already. I have the following images numbered in the order that I discovered everything; they are posted here. I would really appreciate the help. P.S.: Since I am using a PC and not mac, I thought I had to use another command line like BASH or the terminal on my PCor doI just use Ubuntu? The UNIX shell is supposed to start with a $, right? Please correct me if I a wrong and thank you for your help

linux commands on windows can be ran via cmder or git bash (what i had used in past)
and in linux the desktop is at the path
/home/< username>/Desktop
whereas in windows its
C:\Users<username>\Desktop
both windows (DOS) and ubuntu/mac(linux) environment are entirely different you can directly run commands of one on the other environment, you do need to "setup" that env first if the command is not native to that.
Now, since its assignments that you are doing and all you need is bare-min linux env
you can give https://repl.it/ a try and create a new project in bash
Also, when you install Ubuntu on windows you dont get acces to windows like path, like "C:...", in ubuntu c:\ of windows is mounted to some other path in ubuntu
search on google how to access windows desktop from ubuntu shell after installing ubuntu inside of windows

When using Windows Subsystem for Linux (WSL), your C drive is located under /mnt/c.
Judging from the screenshot, you are user 12094, so you can either accept this, or you need to actually configure your machine. Also if you look in the screenshot you provided, there is a /home folder which I am betting is actually pointing to /mnt/c/, and your home folder will be under /home/12094, which is also the same as what is stored in $HOME.
To find the location of a file called data-shell, you can run the following linux command while in your home folder:
find $HOME -type f -name 'data-shell'
This command recursively searches for files in your home directory, with the name data-shell

Execute this command line in Windows

I'm trying to connect my firebase auth to an expo project.
I'm following the main docs of each library. I'm stucking on this step.
I'm not able in windows to exeute this command line openssl rand -base64 32 | openssl sha1 -c.
I've tried with the specific https://code.google.com/archive/p/openssl-for-windows/downloads but I don't know how to reproduce the same line.
Any help would be great, thanks in advance.
You need to install openssl. It is usually available on Linux (which I think that article might have been written for). There are some Windows binaries available at here. Alternatively, you could setup a WSL session, and run the command from there.
that is a linux command. Therefore a linux terminal is needed.
there are at least 2 ways to get this done
using virtual machine with ubuntu or some other operating system that uses a linux terminal aka shell (which I doubt you know about)
OR
installing a linux emulator (windows 8+ since it's from the windows store)
assuming you would prefer option 2, go to the windows store, search "Kali" and you will find an app called Kali. install it and if an error shows up, here's a nice video here that talks about solving that error and you would have a kali terminal on your windows computer (your command would work there)

Can't find a way to get graphic tablet drivers working on mint

So i was trying to install the XP Pen Driver for my Deco 01 v2 graphics tablet on my Linux Mint 19.2 Tina when i came to encounter the following error:
./Pentablet_Driver: /usr/lib/x86_64-linux-gnu/libQt5Core.so.5: version `Qt_5.10' not found (required by ./Pentablet_Driver)
I went on to install qt 5.10, still the same error. Others suggested to just change the path wth sudo gedit /etc/ld.so.conf.d/randomLibs.conf which didn't change a thing.
Link to drivers:
https://www.xp-pen.com/download-440.html
The manufacturer has a page describing how to set up their software on Linux with pictures. However, when following them, you end up with a folder name somewhere along the line that has spaces in it, which causes issues.
So a modified set of instructions might look like this:
Connect your XP-Pen product to the computer.
Download the Linux Beta driver from XP-Pen official website.
When the download is complete, extract the compressed folder.
Rename the extracted folder to something without spaces.
Inside the renamed folder is another compressed folder which should be extracted.
Inside the final extracted folder, ensure "Pentablet_Driver.sh" has execution permissions by right clicking on it and going to "Properties->Permissions" and verifying that "Allow executing file as program" is checked.
Open the terminal. (CTRL+ALT+T)
Type "sudo ", then drag Pentablet_Driver.sh from the file browser onto the terminal.
Type the password to complete.
Make sure that you write exactly
sudo ./Pentablet_Driver.sh
instead
sudo ./Pentablet_Driver
I had the same error until I noticed that I forgot to add .sh at the end.

Custom home not working when console run manually (cygwin)

I was trying to set a new home directory for Cygwin, but the thing is I've managed to do so only partially.
I changed the 'db_home:' parameter (cygwin64/etc/nsswitch.conf) to '/windows' so it now matches the win10 default home folder, but the trick works only if mintty.exe was run through cmd.
Running mintty manually with a desktop shortcut results with the very same default directory as if the file was never changed.
Having all that said, I'm a total newbie when it comes to both Cygwin and Unix in general, so it's very likely I missed something obvious.
I appreciate any help provided, thanks in advance.

rsync fail because of file permission

I was using a dual boot system and backing up in Linux my files using rsync and link-dedt and everything was working perfectly. Because the computer is mostly logged in Windows I decided to install cygwin and try to use rsync to do my backups. That way I can have a script that runs automatically every week. However when I tried to continue my backup using link-dest in cygdrive it didn't work. I think is because the files permission are seen differently by cygwin and Linux.
My command was something like:
rsync -av --exclude-from=exclude.txt --progress --link-dest=/cygdrive/e/2016-02-19/ /cygdrive/d/Users/ /cygdrive/e/2016-02-24/
I looked at files that I knew didn't change in the link-dest and source location and everything looks the same except for the file persmission. How can I omit permissions or solve this problem?
Cygwin on windows does cause lots of strange permissions.
If i was backing windows to a linux host, i would use https://acrosync.com/ which is native rsync for windows, unfortunately it does cost money.
We gave up on cygwin rsync partially due to these issues and ended up developing our own windows replication tool http://www.yintersync.net. Its free for non-commercial use.

Why does configure.sh think win32 is Unix?

I'm trying to build an application from source in windows that requires some Unix tools. I think it's the apparently standard ./configure; make; make install (there's no INSTALL file). First I tried MinGW but got confused that there was no bash, autoconf, m4, or automake exes in \bin. I'm sure I missed something obvious but I installed Cygwin anyways just to move forward. For some reason when I run
sh configure.sh
I get:
platform unix
compiler cc
configuration directory ./builds/unix
configuration rules ./builds/unix/unix.mk
My OS has identity problems. Obviously the makefile is all wrong since I'm not on unix but win32. Why would the configure script think this? I assume it has something to do with Cygwin but if I remove that I can't build it at all. Please help; I'm very confused.
Also is it possible to build using MinGW? What's the command for bash and is mingw32-make the same as make? I noticed they're different sizes.
Everything is fine. When you are inside CygWin, you are basically emulating an UNIX. sh runs inside CygWin, and thus identifies the OS correctly as Unix.
Have a look at GCW - The Gnu C compiler for Windows
Also, you might be interested in this help page, that goes into some detail about the minimal system (MSYS), such as how to install, configure et. c.
That should help you get bash, configure and the rest to work for MinGW as well.
From the Cygwin home page
Cygwin is a Linux-like environment for Windows. It consists of two parts:
A DLL (cygwin1.dll) which acts as a Linux API emulation layer providing substantial Linux API functionality.
A collection of tools which provide Linux look and feel.
Since configure is using the Cygwin environment, it is interacting against the emulation layer and so it is just like it's working on a Unix environment.
Have you tried building the application and seeing if it works?
