Update 3:

tarjae@DESKTOP-LNI8ONS:/home/shiny$ sudo service shiny-server start

I get:

tarjae@DESKTOP-LNI8ONS:/home/shiny$

Nothing happens. Last days I read a blog where I should create a new user and I did and with this new user I could see something on localhost:3838. I am sorry to take your time!

If I do:

tarjae@DESKTOP-LNI8ONS:~$ service shiny-server status
#OR
tarjae@DESKTOP-LNI8ONS:~$ sudo service shiny-server status
# I get:
tarjae@DESKTOP-LNI8ONS:~$ 

1. I am new to linux.
2. I try to deploy a shiny server locally on my windows machine with ubuntu WSL.
3. I successfully installed ubuntu WSL on my windows machine and I can start ubuntu.

• I come here so far:

• If I type dir I get this:

From now on everything that happens is random for me, depending on which tutorial I go through!

So my question is:

1. How can I check whether I am the root or a user? (Source for basic managing linux commands)?
2. Where is my shiny server?
3. How can I start the server sudo start shiny-server does not work ->

4. And finally how can I start app1.R

I am fully aware that all this is kind of wage. But I hope to get the next step for my purposes. ANY directing advice is highly appreciated.

Update1:

dpkg-query -l shiny shows

dpkg-query: no packages found matching shiny

• After sudo apt install ./shiny-server-1.5.17.973-amd64.deb it shows:

Note, selecting 'shiny-server' instead of './shiny-server-1.5.17.973-amd64.deb'
shiny-server is already the newest version (1.5.17.973).
0 upgraded, 0 newly installed, 0 to remove and 12 not upgraded. 

Update 2:

With

tarjae@DESKTOP-LNI8ONS:~$ dpkg-query -l | grep shiny

I get:

ii  shiny-server                   1.5.17.973                            amd64        Shiny Server

• Then with

tarjae@DESKTOP-LNI8ONS:~$ systemctl start shiny-server

I get:

tarjae@DESKTOP-LNI8ONS:~$ systemctl start shiny-server
