Is there a way to determine all users on a system that the users command doesn't seem to show? like _x11 and _ntpd
What's a user? Maybe you want to look at /etc/passwd. The first four lines are root:*:0:0:Charlie &:/root:/bin/ksh daemon:*:1:1:The devil himself:/root:/sbin/nologin operator:*:2:5:System &:/operator:/sbin/nologin bin:*:3:7:Binaries Commands and Source:/:/sbin/nologin You can parse that with awk and do stuff. Read about passwd(5) to understand the format. A login shell of /sbin/nologin means it isn't interactive. That might get you started? --STeve Andre'
