if you are just trying to get UIDs then

sudo less /etc/passwd

should give all your registered users (system, user, etc. ) an example is:
...
lightdm:x:112:118:Light Display Manager:/var/lib/lightdm:/bin/false
...

this line is colon delimited and the first number after the "x" is the 
UID. (in this case 112)

Here is some information to understand fully:
