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. SEE ALSO
