MAKEDEV(8)						      System Manager's Manual							MAKEDEV(8)

NAME

       makedev - make system special files

SYNOPSIS

       /dev/MAKEDEV device...

DESCRIPTION

       MAKEDEV is a shell script normally used to install special files.  It resides in the /dev directory, as this is the normal location of spe-
       cial files.  Arguments to MAKEDEV are usually of the form device-name?  where device-name is one of the supported devices listed in section
       4  of  the  manual and ``?'' is a logical unit number (0-9).  A few special arguments create assorted collections of devices and are listed
       below.

       std    Create the standard devices for the system; e.g. /dev/console, /dev/tty.	The VAX-11/780 console	floppy	device,  /dev/floppy,  and
	      VAX-11/750 and VAX-11/730 console cassette device(s), /dev/tu?, are also created with this entry.

       local  Create  those  devices specific to the local site.  This request causes the shell file /dev/MAKEDEV.local to be executed.  Site spe-
	      cific commands, such as those used to setup dialup lines as ``ttyd?'' should be included in this file.

       Since all devices are created using mknod(8), this shell script is useful only to the super-user.

DIAGNOSTICS

       Either self-explanatory, or generated by one of the programs called from the script.  Use ``sh -x MAKEDEV'' in case of trouble.
