How do you show the properties of a file?

The command to show the properties of a file is ls -l. This command provides a detailed listing of files in the current directory, outputting various file attributes such as permissions, number of links, owner name, group name, file size, and the last modified date and time, followed by the filename.

This information is essential for understanding access rights to the file and its ownership, which is fundamental for managing files in a Linux environment. Understanding these details can help in troubleshooting permission issues and administering the system effectively.

The other options do not serve this purpose: displaying a file's contents, changing its permissions, or attempting to access its documentation do not provide the comprehensive properties that ls -l does.
