Type uni and use shell completion to find out if it is anywhere in your $PATH.

what command did you use to install it
or the much easier and better to type
" sh *.run "

the run is a script with a binary payload to install

normally there is a "HELP" option
this will give you instructions and options

It even gives me an installation directory where it is installed.

/opt/unicentaopos-3.91.2

jason@jason-P55-USB3 ~ $ sh unicentaopos-3.91.2-linux-x64-installer.run
sh: 0: Can't open unicentaopos-3.91.2-linux-x64-installer.run

Hi...

It's not uniCentra, with an "r," it's just uniCenta. Try opening a terminal and pasting in the name below and pressing "Enter" and see what happens...

Let is know what you find out.

Regards...

That's what I wrote 4 hours ago in post #11 ... OP wasn't interested.

Hi...

Thanks, I didn't see your post.

Regards...

If all of unicentaopos's binaries are in the /opt directory and you restarted your pc than opening the terminal and typing unicentaopos should launch the program.
If not than if it's installed it would show in your applications menu or in your launcher.

Is there a README file in the /opt directory where the program is?

jason@jason-P55-USB3 ~ $ unicentaopos
unicentaopos: command not found
jason@jason-P55-USB3 ~ $

Yes, it's unicenta. I realized that shortly after I started the thread. However, unicentra, unicenta, unicentaopos, or any other way I can spell it still cannot be found.

While reading some beginner Linux pages, I run across a ls command, so I type in ls in terminal and here are the results:

jason@jason-P55-USB3 ~ $ ls
Desktop Downloads Pictures rtl8812AU_8821AU_linux unicentaopos-3.91.2
Documents Music Public Templates Videos
jason@jason-P55-USB3 ~ $



As you can see unicentaopos shows up. I don't know what that means, but there it is.

This cannot be that hard. I installed it to desktop so I can find it. I can click on it and this is what comes up.

Now what do I do??

I click start.sh and this comes up:

Maybe Linux just isn't for me. I can figure out most things and I can only imagine a little old lady trying to figure out this OS. AS long as it's been around you'd think it would have become much easier to navigate by now. This is unreal.

However, I still want to learn it, but there's very little support, here and on the internet. The only 2 things I've tried to do so far is get a wireless adapter working (with no luck although I got it going but it shuts down after a little bit then cannot get it back up) and install unicenTa. Both have been a nightmare.

I'm willing to stick with it a little longer but Windows is looking like all-world at this point.
