NAME
       btrfs - control a btrfs filesystem

SYNOPSIS
       btrfs <command> [<args>]

DESCRIPTION
       btrfs is used to control the filesystem and the files and directories
       stored. It is the tool to create or destroy a snapshot or a subvolume
       for the filesystem, to defrag a file or a directory, flush the data to
       the disk, to resize the filesystem, to scan the device.

       It is possible to abbreviate the commands unless the commands are
       ambiguous. For example: it is possible to run btrfs sub snaps instead
       of btrfs subvolume snapshot. But btrfs file s is not allowed, because
       file s may be interpreted both as filesystem show and as filesystem
       sync.

       If a command is terminated by --help, the detailed help is showed. If
       the passed command matches more commands, detailed help of all the
       matched commands is showed. For example btrfs dev --help shows the help
       of all device* commands.
