This command is using the raw
utility to associate a raw character device with the specified block device.
Here is a breakdown of the command syntax and its components:
raw
is the command/utility being executed./dev/raw/raw${1}
refers to a special block device file in the Linux filesystem hierarchy.${1}
is a placeholder for the first argument passed to the command (e.g., if the command is executed withraw 0
, the file path becomes/dev/raw/raw0
).- In Linux, raw character devices are used to bypass the filesystem and perform direct I/O. They provide lower-level access to device I/O operations, allowing applications to bypass certain layers of the operating system and have more control over the data being read from or written to a block device.
/dev/raw/
is the directory where raw character devices are created by the system.
In summary, this command associates a raw character device file with a specified block device, enabling direct I/O access to the underlying device.
