I am a fresher who recently got a job in Linux Admin - maintaining some servers for a client. The server might be a mix of web and app servers, could you please suggest in what areas I need to learn and excel to make sure I shine in the career. As of now I am planning o change from VB.net to Python because Linux server might need scripting to be done in Python and Bash. Could you please specify areas where I need to concentrate. Right now I am only a fresher.
