mknod(1M)                        DG/UX R4.11                       mknod(1M)


NAME
       mknod - build a special file

SYNOPSIS
       /etc/mknod name b|c major minor

       /etc/mknod name p

DESCRIPTION
       Mknod makes a directory entry and corresponding inode for a device
       node or FIFO special file.  Arguments are:

       name    Name of the entry.

       b or c  Indicator that the device node is block-type (e.g., disks) or
               character-type (other devices).  You must have appropriate
               privilege to make device nodes.  For systems supporting the
               DG/UX Capability Option, appropriate privilege is defined as
               having one or more specific capabilities enabled in the
               effective capability set of the user.  See capdefaults(5)
               for the default capabilities for this command.

       On systems without the DG/UX Capability Option, appropriate privilege
       means that your process has an effective UID of root.  See the
       appropriateprivilege(5) man page for more information.

       major   Number specifying the major device type in octal or decimal.
               Octal numbers must begin with the digit 0.

       minor   Number specifying the minor device (e.g., unit, drive, or
               line number) in decimal or octal.

       p       Indicator that mknod is to create FIFOs (named pipes).  Any
               user may create FIFO nodes.

       Major device numbers are assigned dynamically by the system as
       devices are configured.  Minor device numbers are allocated by each
       device driver.  Take note that, in general, it should never be
       necessary to use the mknod command, because all the devices
       configured into your kernel will automatically have nodes created for
       them each time your system is booted.
