intro(7) UNIX System V intro(7)
NAME
intro - introduction to special files
DESCRIPTION
This section describes various special files that refer to specific
hardware peripherals, and UNIX system device drivers. STREAMS [see
intro(2)] software drivers, modules and the STREAMS-generic set of
ioctl(2) system calls are also described.
For hardware related files, the names of the entries are generally
derived from names for the hardware, as opposed to the names of the
special files themselves. Characteristics of both the hardware device
and the corresponding UNIX system device driver are discussed where
applicable.
Disk device file names are in the following format:
/dev/{r}dsk/{1.0}s# For integral disks
/dev/{r}dsk/c#t#d#s# For SCSI disks
where r indicates a raw interface to the disk, the c# indicates the SCSI
host adapter number, t# indicates the SCSI target ID of the device, d#
indicates the device attached to the controller and s# indicates the
section number of the partitioned device.
