How to check system ownership?

To check system ownership in a Linux environment, you can use the following methods:

1. Check File Ownership:
   Use the ls -l command to list files and their ownership in a directory:

   ls -l /path/to/directory

   This will display the owner and group of each file.

2. Check User Information:
   To see the current user and their details, use:

   whoami

   This command shows the username of the currently logged-in user.

3. Check Group Membership:
   To see which groups you belong to, use:

   groups

4. View System Users:
   You can view all users on the system by checking the /etc/passwd file:

   cat /etc/passwd

5. Check System Information:
   To get information about the system, including the hostname and other details, use:

   hostnamectl

6. Check System Logs:
   Review system logs (e.g., /var/log/auth.log or /var/log/secure) for information about user logins and ownership changes.

These commands will help you determine ownership and user information on a Linux system.
