Hello friends,
Please how do I save my project so I can continue when I return, I am currently on this tutorial " Learn Bash Scripting by Building Five Programs" and each time I pause or take a break I notice the progress wont save, but instead I will be redirected to start all over from scratch. Please how do I save progress manually and retrieve it on the Virtual Machine?

There appears to be an issue with progress being saved automatically at the moment. We are trying to investigate and resolve this ASAP!
