User Information Script

This script collects information about users on the system and displays it in a formatted manner. It is written in Bash.

Prerequisites

• Linux operating system (CentOS, Red Hat, or similar)
• Bash shell

Usage

1. Open a terminal.
2. Navigate to the directory where the script is located.
3. Make the script executable, if needed, by running the following command:

   chmod +x script.sh
   

4. Run the script by executing the following command:

   ./script.sh
   

Functionality

• The script first collects information about the "root" user and displays it.
• For Linux systems (CentOS, Red Hat), the script then iterates over all the users in the "/home" directory.
  • It collects information such as creation time, password change time, last login time, user status, UID, GID, password existence, and sudo access.
  • The collected information is displayed for each user.
• For non-Linux systems, the script follows a similar process but with different log files.
• The script uses various commands such as sudo, passwd, id, last, and grep to collect the required information.

Output

The script displays the following information for each user:

• Username
• Creation time
• Password last changed
• Last login time
• User status (enabled or disabled)
• UID (User ID)
• GID (Group ID)
• Password existence (True or False)
• Sudo access information
• Entry in /etc/passwd file
