cut -d: -f1 /etc/passwd
This command will list the usernames of all users in the /etc/passwd
file.
Method 2: Use the graphical interface

Using the command line can obtain user information more quickly, while the graphical interface is more intuitive and easier to use. Choose the appropriate method to view the list of user accounts in the system according to actual needs.
