Hello,

With a terminal on Linux, how to get the 4G data used?

I'm using an Archer MR400 and running my machine on Linux. I wish to develop an app to display the data used. In order to begin, I need to know how to get data used from command line, terminal or script. Please, could you tell how to get 4G data used? Where is the reference guide about commands to communicate with the router? Thanks in advance.
