Need to access the text based interface

I know this is a very basic question but i need it answered. I am trying to build a hybrid cloud environment with opennebula and azure. I have done all the configurations possible from the GUI but i need to access the CLI for azure driver configuration.

Can i please get some help on how to access the CLI as i’m a student with first time exposure to opensource cloud configurations and zero experience with CLIs.


i’m almost at my deadline if i dont get help i fail the project. Please help me out as soon as possible
