This command is used to create a read-only snapshot of a Btrfs subvolume in Linux using the "btrfs subvolume snapshot" command. Here is a breakdown of each part of the command:

"sudo": It is used to execute the command with administrative/root privileges.
"btrfs subvolume snapshot": This is the command itself, which is used to create a snapshot of a Btrfs subvolume.
"-r": It is an option used to create a read-only snapshot. The resulting snapshot cannot be modified or written to.
"${path-to-source_subvolume}": This is the path to the Btrfs subvolume that you want to take a snapshot of. You need to replace this with the actual path to the source subvolume in your system.
"${path-to-target}": This is the destination path where the snapshot will be created. You need to replace this with the desired target path for the snapshot in your system.
