User ID and Group ID. They are used for a first-cut security in Unix systems, in that files and programs can be restricted to certain groups, or to certain users.  Groups are kept in the /etc/group file, users and the group they belong to are kept in the /etc/passwd file.

UID - User id
GID - Group id

We can find out using sample command fire @ $ promoit "id" you will user id & group id.
e. g step 1 : $ id ---> O/p get display immediately
uid=232(vijay) gid=1(staff)

This is actually string in the /etc/password user id = 232 and group = 1 user home directory = :/users/vijay:/usr/ and shell is ksh

vijay:!:232:1:Vijay:/users/vijay:/usr/bin/ksh

To find a user's UID or GID in Unix, use the id command.

To find a specific user's UID, at the Unix prompt, enter:
id -u username
Replace username with the appropriate user's username.

To find a user's GID, at the Unix prompt, enter:
id -g username

If you wish to find out all the groups a user belongs to, instead enter:
id -G username

If you wish to see the UID and all groups associated with a user, enter id
without any options, as follows:
id username
