Whats up Everybody?! I am still somewhat new to macs but I was curious about looking up my user accounts through terminal on my macbook pro late 2011, Snow Leopard 10.6.8. I checked out a couple of forums and tried out this command line in terminal: dscl . list /Users | grep -v "^_". after I typed it in my four main user accounts popped up plus a "root", a "daemon" and a "nobody". What are the "root", the "daemon" and the "nobody" accounts? Why is there even a "nobody" account? Is this a hacker created hidden account? Thanks everyone.
