It is possible to abbreviate the commands unless the commands are ambiguous. For example: it is possible to run
btrfs sub snaps
instead ofbtrfs subvolume snapshot
. Butbtrfs file s
is not allowed, becausefile s
may be interpreted both asfilesystem show
and asfilesystem 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 examplebtrfs dev --help
shows the help of alldevice*
commands.
