how can i open it?
and i type o and like this:
how can i open it?
Start it with ./start-ursim.sh UR10 if you want it to start as an UR10
There is an urcap_tutorial.pdf on the virtual machine too, I would recommend you started by having a look at that. It will give you information about where things are located, and some information about what the different things do, and also how you create a new URCap.
You need to open it from a new terminal.
Create a terminal, and type:
cd /home/ur/ursim/ursim-3.7.2.40245
Then you are in the correct path. If you type then:
./start-ursim.sh
It will work 
I highly recommend if you’ve need more info to search how to manage a terminal in Linux. There’re a lot of tutorials and posts in Internet
thanks for ur Information,and i have try it and the result is below:
did i make something wrong?
beacause im new for Linux too
thanks for the Information,i will try it !
I think that you didn’t enter in the directory correctly. Pay attention, there’s a blank space or gap between cd and home:
Incorrect
cd/home/ur/ursim/ursim-3.7.2.40245
Correct
cd /home/ur/ursim/ursim-3.7.2.40245
If you type a space between cd and home it will work

Access directory Linux
finally it works！！thank you very much for your help!!!
