raw: Bind a raw character device to a block device.
$ raw /dev/raw/raw${1} ${-dev-block_device}
try on your machine
This command is used to create a device file named "raw" in the /dev/raw directory, with the help of the argument passed to the script (denoted as $1) appended to the end of the file name. Additionally, the script also passes the argument "-dev-block_device" to the command.
Here's a breakdown of the components:
raw
: It represents the command or utility being executed. In this case, it is the "raw" utility, which is used to create raw device files./dev/raw/
: It is the directory where the raw device file will be created. "/dev/raw" is a specific directory in the Linux filesystem dedicated to raw devices.raw${1}
: This denotes the name of the raw device file that will be created. The${1}
is a shell variable that will be replaced with the first argument passed to the script when it is called.${-dev-block_device}
: This represents the second argument passed to the script, which is intended to specify the block device that will be associated with the raw device. The-dev
part implies that the device will be considered as a block device.
Overall, this command is typically used to create a raw device file and associate it with a specific block device, providing a way for applications to directly access the block device at a low-level, without any filesystem or buffering performed by the operating system.

never run a command you are not sure if it is safe.
