Get User ID (UID) for Users on Ubuntu Linux

Finding User ID (UID) for users on an Ubuntu Linux system is easy and straightforward. There are a couple of different commands that can be used to obtain the UID for any user on the system.

The first way to get your User ID is to use the id command as shown below:

id

The command above will display output a similar the below:

Output

uid=1000(mkumar7742) gid=1000(mkumar7742) groups=1000(mkumar7742),4(adm),20(dialout),24(cdrom),25(floppy),27(sudo),29(audio),30(dip),44(video),46(plugdev),116(netdev)

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.

Therefore, to obtain the UID of any particular user, execute the lslogins command below, which will assist in obtaining the desired User ID.

Run the lslogins command to list all UIDs on the system as shown below:

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 <username>

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
