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.
