mkfs.btrfs:tldr:0334b
This command is used to create a Btrfs filesystem on a specified storage device or devices. Let's break down the different elements:
-
sudo
: It's a command used to run subsequent commands with administrative privileges. It allows the user to execute the following command as a superuser or administrator. -
mkfs.btrfs
: This command is used to create a Btrfs filesystem. It is specific to the Btrfs file system and is responsible for initializing the file system on the specified storage device(s). -
--label "${label}"
: This option is used to assign a label to the newly created Btrfs filesystem. The${label}
is a placeholder that would be replaced with the actual desired label. The label serves as a human-readable identifier for the file system. -
${-dev-sda}
and[${-dev-sdN}]
: These placeholders represent the storage device(s) on which the Btrfs filesystem will be created. The-dev-sda
denotes the first storage device, and the-dev-sdN
represents additional storage devices if desired. Replace${-dev-sda}
and[${-dev-sdN}]
with the actual device names, like/dev/sda
,/dev/sdb
, etc.
Overall, this command allows you to create a Btrfs filesystem on one or more storage devices, with an optional label assigned to it. The system executes it with administrative privileges using sudo
.
