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.
