MKNOD(8) MKNOD(8)
NAME
mknod - construct special file
SYNOPSIS
/etc/mknod name [ c ] [ b ] major minor
DESCRIPTION
Mknod makes a special file. The first argument is the name
of the entry. The second is b to make a file for a block
device, c to make a character device. The last two argu-
ments are numbers specifying the major device type and the
minor device (e.g. unit, drive, or line number).
Minor devices are specific to each device driver; see the
writeups in Section 4. The assignment of major device num-
bers varies with the implementation. Here are some conven-
tional ones in the system used on VAXes:
