For example +*btrfs dev --help* shows the help of all *device** commands. + +COMMANDS +-------- +*balance*:: + Balance btrfs filesystem chunks across single or several devices. + + See `btrfs-balance`(8) for details. + +*check*:: + Do off-line check on a btrfs filesystem. + + See `btrfs-check`(8) for details. + +*device*:: + Manage devices managed by btrfs, including add/delete/scan and so + on. + + See `btrfs-device`(8) for details. + +*filesystem*:: + Manage a btrfs filesystem, including label setting/sync and so on. + + See `btrfs-filesystem`(8) for details. + +*inspect-internal*:: + Debug tools for developers/hackers. + + See `btrfs-inspect-internal`(8) for details. + +*property*:: + Get/set a property from/to a btrfs object. + + See `btrfs-property`(8) for details. + +*qgroup*:: + Manage quota group(qgroup) for btrfs filesystem. + + See `btrfs-qgroup`(8) for details. + +*quota*:: + Manage quota on btrfs filesystem like enabling/rescan and etc. + + See `btrfs-quota`(8) and `btrfs-qgroup`(8) for details. + +*receive*:: + Receive subvolume data from stdin/file for restore and etc. + + See `btrfs-receive`(8) for details. + +*replace*:: + Replace btrfs devices. + + See `btrfs-replace`(8) for details. + +*rescue*:: + Try to rescue damaged btrfs filesystem. + + See `btrfs-rescue`(8) for details. + +*restore*:: + Manage a btrfs filesystem, including label setting/sync and so on. + + See `btrfs-restore`(8) for details. + +*scrub*:: + Scrub a btrfs filesystem. + + See `btrfs-scrub`(8) for details. + +*send*:: + Send subvolume data to stdout/file for backup and etc. + + See `btrfs-send`(8) for details. + +*subvolume*:: + Create/delete/list/manage btrfs subvolume. + + See `btrfs-subvolume`(8) for details. + +EXIT STATUS +----------- +*btrfs* returns a zero exit status if it succeeds.
