#USE GREP COMMAND IN LINUX TO FIND FAILED LOGIN ATTEMPTS PASSWORD#
Is it possible that someone knowing the password to my machine, can log in and change the log file to remove all traces that they got in? Below I have highlighted the 2 entries that caught my eye. I was looking at my log files and noticed something unsual, a gap between when I last shut down my PC and when I started it, doesn't show session closed or anything for when I shut it off, just stops at this "Failed to activate service 'org.bluez': message and that's it.
