Use the lslogins command to find the User ID

The lslogins command is useful for discovering multiple users’ user IDs (UIDs). Specifying the -u option to this command will generate a list of all users’ IDs on the system.

lslogins -u

UID   USER         PROC PWD-LOCK PWD-DENY LAST-LOGIN GECOS
0     root         4                                 root
1000  mkumar7742   2                                 ,,,

How to Get User IDs using the getent command

Another convenient way to view a user ID or UID is by using the getent command. Run the following command format to get the UID of any user.

getent passwd 

The command above extracts UIDs for users by accessing the content of the /etc/passwd file.

Example:

getent passwd mkumar7742

Output:

mkumar7742:x:1000:1000:,,,:/home/mkumar7742:/bin/bash
