BTRFS(8)                                   Btrfs Manual                                  BTRFS(8)

NAME
       btrfs - control a btrfs filesystem

SYNOPSIS
       btrfs  []

DESCRIPTION
       The btrfs utility is a toolbox for managing btrfs filesystems. There are command groups to
       work with subvolumes, devices, for whole filesystem or other specific actions. See section
       COMMANDS.

COMMAND SYTNAX
       Any command name can be shortened as far as it stays unambiguous, however it is
       recommended to use full command names in scripts. All command groups have their manual
       page named btrfs-.

       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 the command name is ambiguous, the list of conflicting options is printed.

       For an overview of a given command use btrfs command --help or btrfs [command...] --help
       --full to print all available options.
