User ID in Linux
To print user ID in Linux, we can use id command.
id
Example 1 – User Id of root user
In this example, we get the user ID of root user.
![Linux - Get User ID](https://www.tutorialkart.com/wp-content/uploads/2023/03/linux-print-user-id-1.png)
We are currently logged in as root.
root@tutorialkart#
To get the user ID of root user, execute the id command.
root@tutorialkart# id uid=0(root) gid=0(root) groups=0(root)
uid
is our user ID. id prints group id gid
and groups
information as well, along with the user ID.

Example 2 – User ID of another user
In this example, we get the user ID of user prasanna (who is logged in right now).
![Linux - Get user id](https://www.tutorialkart.com/wp-content/uploads/2023/03/linux-print-user-id-2.png)
Now we have logged in as another user, say prasanna.
prasanna@tutorialkart#
Let us get the user ID of this user using id command.
prasanna@tutorialkart# id uid=1000(prasanna) gid=1000(prasanna) groups=1000(prasanna) ,4(adm) ,24(cdrom) ,27(sudo) ,30(dip) ,46(plugdev) ,120(lpadmin) ,131(lxd) ,132(sambashare)
Conclusion
In this Linux Tutorial, we learned how to get the user ID of current user using id command.
