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

NAME
MAKEDEV, DESCRIBE - make/describe device files SYNOPSIS
MAKEDEV [-n] key ... DESCRIBE [device] ... DESCRIPTION
MAKEDEV may be used to create the device files normally found in the /dev directory. The key arguments are simply the names of the devices you want. MAKEDEV knows about all supported devices and will create them in the current directory with the proper owner and mode. For many devices MAKEDEV will not only create the device you want, but also the devices related to it that you will probably want too. Naming one floppy device will create all floppy devices for the same drive for instance. Call MAKEDEV without arguments to see a list of keys that it understands. Then use the -n flag to make the script echo the commands it will execute the next time when you call it without that flag. The special key std must be given alone to MAKEDEV. This key will create all standard devices. The command DESCRIBE will give you a one-line description of a given device. It will by default list all devices in /dev. SEE ALSO
mknod(8). BUGS
MAKEDEV's eagerness to create devices may cause many "File exists" errors from mknod. AUTHOR

NAME
mknod -- make device special file SYNOPSIS
mknod [-F format] name [c | b] major minor [-F format] name [c | b] major unit subunit name [c | b] number name [p] DESCRIPTION
The mknod command creates device special files. Normally the shell script /dev/MAKEDEV is used to create special files for commonly known devices; it executes mknod with the appropriate arguments and can make all the files required for the device. To make nodes manually, the required arguments are: name Device name, for example ``sd'' for a SCSI disk on an HP300 or a ``pty'' for pseudo-devices. b | c | p Type of device. If the device is a block type device such as a tape or disk drive which needs both cooked and raw special files, the type is b. All other devices are character type devices, such as terminal and pseudo devices, and are type c. To create named pipes the type p can be used. major The major device number is an integer number which tells the kernel which device driver entry point to use. To learn what major device number to use for a particular device, check the file /dev/MAKEDEV to see if the device is known, or check the system depen- dent device configuration file: ``/usr/src/sys/conf/device.architecture'' (for example device.hp300). minor The minor device number tells the kernel which one of several similar devices the node corresponds to; for example, it may be a spe- cific serial port or pty. unit and subunit The unit and subunit numbers select a subset of a device; for example, the unit may specify a particular SCSI disk, and the subunit a partition on that disk. (Currently this form of specification is only supported by the bsdos format, for compatibility with the BSD/OS mknod(8) .) Device numbers for different operating systems may be packed in a different format. To create device nodes that may be used by such an oper- ating system (e.g. in an exported file system used for netbooting), the -F option is used. The following formats are recognized: native, 386bsd, 4bsd, bsdos, freebsd, hpux, isc, linux, netbsd, osf1, sco, solaris, sunos, svr3, svr4 and ultrix. Alternatively, a single opaque device number may be specified. SEE ALSO
