btrfs:tldr:3a364

This command is used to display the disk usage and space statistics for a Btrfs filesystem. Let's break it down:

• sudo: It is a command that allows a user to run programs or execute commands with the privileges of a superuser or another specified user. The sudo command must be used by a user with administrative privileges to execute the following command.

• btrfs filesystem df: This is the main command that is used to display the disk usage and space statistics for a Btrfs filesystem. The df stands for "disk free" and is a common command used to display filesystem usage information on Unix-like systems.

• ${path-to-mount_point}: This is a placeholder that represents the full path to the mount point of the Btrfs filesystem you want to analyze. You need to replace ${path-to-mount_point} with the actual path to the mount point directory. For example, if your Btrfs filesystem is mounted at /mnt/btrfs, you would replace ${path-to-mount_point} with /mnt/btrfs.

When you execute this command, it will display information about the usage, total space, and available space for the specified Btrfs filesystem mounted at the provided mount point.
