Step 1: Accessing the Server

The first step in checking the number of created user accounts on your Linux server is to access the server. You can do this by logging in as the root user. The root user has full administrative access and can perform any task on the server.

Open your terminal. This could be a terminal on a Linux or macOS system, or a program like PuTTY if you’re using Windows.

Use the Secure Shell (SSH) protocol to connect to your server. The general command is:

ssh root@your_server_ip

Replace ‘your_server_ip’ with the IP address of your server.

After running this command, you’ll be prompted to enter the root password. Type in the password and press Enter. Remember, the characters won’t display as you type the password, which is a standard security feature.

If the password is correct, you’ll be logged in as the root user and can start managing your server.

Step 2: Running the Command

Once you’ve logged into your server, you can check the number of created user accounts by running the following command:

cat /etc/passwd | wc -l

This command reads the /etc/passwd file, which contains user account information, and pipes the output to the ‘wc -l’ command, which counts the number of lines. The result is the total number of user accounts on your server.

For example:

[root@centos62 ~]# cat /etc/passwd | wc -l
38

Commands Mentioned:

  • cat /etc/passwd – This command reads the /etc/passwd file, which contains user account information.
  • wc -l – This command counts the number of lines in the input it receives. In this case, it’s counting the number of user accounts.
