btrfs-inspect-internal:tldr:5e408

The command you provided, sudo btrfs inspect-internal tree-stats ${path-to-partition}, is used to inspect and retrieve statistics about the Btrfs file system tree on a specific partition.

Here's a breakdown of the command:

• sudo: This is a command used in Unix-like systems to execute a command with administrative privileges. It allows you to run the command as the superuser (root) or another user with administrative rights.

• btrfs: This is the command-line utility for managing the Btrfs file system. The btrfs command is followed by a subcommand, which in this case is inspect-internal.

• inspect-internal: This subcommand is used to access internal information and stats of the Btrfs file system.

• tree-stats: This is a specific option of the inspect-internal subcommand. It is used to request statistics about the Btrfs file system tree.

• ${path-to-partition}: This placeholder is intended to be replaced with the actual path to the Btrfs partition you want to inspect. For example, it could be /dev/sda1 or /mnt/btrfs.

When you run this command with the appropriate path to your Btrfs partition and with administrative privileges, it will retrieve and display statistics about the file system tree on that partition. These statistics may include information about the number of directories, files, extents, bytes used, and various tree-related metrics.
