I'm kinda a newbie to ubuntu (only been using it for about 6 months) and I love it! I have been trying to get used to the terminal interface and I use it for a lot of things relating to securing my computer (firewalls, and stuff like that) and so as I try and work on improving my terminal skills I have also been trying to move away from the GUIs. I want to know if there is a command were I can get all the information listed in the User Accounts GUI (for example account type, password options, automatic login etc) in terminal.

The best way to find out information about users is through /etc/passwd and /etc/group files.
For instance awk -F : '!/nobody/ && $3>1000 {print $1}' will tell you all the human users on the system and cat /etc/group |grep sudo will tell you who has sudo privilleges
Automatic login is generally configured in /etc/lightdm/lightdm.conf
There is also /var/lib/AccountsService/users folder where you can find some minor information on users who use graphical login. For instance, here is mine
[com.canonical.indicator.sound.AccountsService]
PlayerName=''
Timestamp=0
Title=''
Artist=''
Album=''
ArtUrl=''
PlayerIcon=<('themed', <['application-default-icon', 'application-default', 'application']>)>
[User]
Language=en_US
FormatsLocale=en_US.UTF-8
XSession=gnome
Background=/usr/share/backgrounds/LOGIN-WARNING.png
Icon=/usr/share/pixmaps/faces/penguin.jpg
SystemAccount=false
[InputSource0]
xkb=us
[InputSource1]
xkb=ru
[InputSource2]
ibus=sunpinyin
[InputSource3]
ibus=libpinyinThere is also file /etc/shadow.
To list the currently logged-on users, type who.
To identify the current user, type whoami.
