Is it possible to analyze the blockchain through some command line?
I also assume you're running the Bitcoin-QT GUI, so you have a console accessible at Window > Console which you can run all the RPC commands in without opening a command prompt or powershell.
IMO Bitcoin-qt console isn't practical for serious analysis / retrieving lots of data. You can't use pipe (to run multiple command or call another application to process the output) or redirect output to file.
