Ever wondered who has access to your Linux system? Knowing how to list users is crucial for security and administration. The simplest way? The `cat /etc/passwd` command. This displays a wealth of user information, but can be overwhelming. For a cleaner list of usernames, try `cut -d: -f1 /etc/passwd`.
But listing is just the beginning! For more granular control, explore the `getent passwd` command, which pulls user data from various sources.
User management doesn't stop there. Consider learning how to add users (`useradd`), modify user properties (`usermod`), and remove users (`userdel`). Mastering these tools empowers you to maintain a secure and well-organized Linux environment. So, go ahead, take control of your users!
