What is the command to list all users in Linux?

You can use the following command in Linux to list all users:

1. The command “cat /etc/passwd” will display the contents of the /etc/passwd file, which contains all the user information on the system.
2. This command uses a colon as a delimiter to extract the first field, which is the username, from the /etc/passwd file.
3. The command “awk -F: ‘{print $1}’ /etc/passwd” uses “:” as a delimiter to extract the first field, which is the username, from the “/etc/passwd” file.
4. This command uses a colon as a delimiter to extract the first field, which is the username, from the output of the getent passwd command.
5. compgen -u: This command will display all usernames on the current system, including system users and regular users.
