stat:tldr:bee1c

This command is used to obtain information about the file system of a specific file.

Here's a breakdown of the command:

• stat is a command-line utility in Unix-like operating systems that displays detailed information about the specified file(s). It is short for "status".
• --file-system is an option or switch for the stat command. When this flag is used, stat will display information about the file system rather than the specific file.
• ${filename} is a placeholder for the name or path of the file you want to examine the file system information for.

When you run this command and replace ${filename} with the actual file name or path, it will display various details about the file system associated with that file. This may include information such as the file system type, the block size, the number of blocks allocated, the total size, the number of free blocks, the inode number, and more.
