How to list active users?

To list active users currently logged into a Linux system, you can use one of the following commands:

Using the who command:
```
who
```
This command displays a list of users currently logged in, along with their login time and terminal information.
Using the w command:
```
w
```
This command provides a more detailed view, showing who is logged in and what they are doing, including their idle time and the command they are currently executing.
Using the users command:
```
users
```
This command simply lists the usernames of users currently logged in, without additional details.

Any of these commands will help you identify active users on your system!
