What is the output of the 'stat' command in Linux?

• A. Display the current username
• B. View system load averages
• C. Detailed information about a file
• D. Remove duplicate files

Answer: (C)

The output of the 'stat' command in Linux provides detailed information about a file or filesystem. When you run the command followed by a filename, it returns various attributes associated with that file, including its size, permissions, ownership (user and group), the last access and modification times, and the inode number. This comprehensive information helps users and system administrators understand the properties of a file within the filesystem.

In contrast to this, displaying the current username pertains to commands like whoami or id, which are unrelated to the 'stat' command's functionality. Viewing system load averages is typically done with commands such as uptime or top, which provide insights into the system's resource usage over time. Removing duplicate files is a task that would require different types of commands or tools (such as fdupes or other file management utilities) and is not addressed by the 'stat' command.
