||||

|
||||
.Nd make/describe device files
|
||||
.Sh SYNOPSIS
|
||||
.Nm MAKEDEV
|
||||
.Op Fl n | Fl m
|
||||
.Op Fl r | Fl s
|
||||
.Op key ...

.Nm DESCRIBE
|
||||
.Op device ...
|
||||
.Sh DESCRIPTION
|
||||
.Nm MAKEDEV
|
||||
may be used to create the device files normally found in the /dev directory.
|
||||
.Nm MAKEDEV
|
||||
knows about all supported devices and will create them in the current
|
||||
directory with the proper owner and mode. For many devices
|
||||
.Nm 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.
|
||||
.Pp
|
||||
The options are as follows:
|
||||
.Bl -tag -width Xxxexcludexfilexx
|
||||
.It Fl n
|
||||
echo the commands it would execute when you call it without that flag.
|
||||
.It Fl m
|
||||
echo
|
||||
.Nm mtree(8)
|
||||
formatted lines instead of creating the device nodes.
|
||||
.It Fl r
|
||||
Restricted set of devices. This set is used when generating the ramdisk.
|
||||
.It Fl s
|
||||
Standard set of devices. This set is used when popluating /dev.
|
||||
.El
|
||||
.Pp
|
||||
.Ar key
|
||||
arguments are simply the names of the devices you want to create. Call
|
||||
.Nm MAKEDEV
|
||||
without arguments to see a list of keys that it understands.
|
||||
.Pp
|
||||
The command
|
||||
.Nm DESCRIBE
|
||||
will give you a one-line description of a given device. By default It
|
||||
will list all devices in /dev.
|
||||

||||

|
||||
.Xr mknod 8
|
||||
.Sh BUGS
|
||||
The eagerness of
|
||||
.Nm MAKEDEV
|
||||
to create devices may cause many "File exists" errors from
|
||||
.Nm mknod .

.TH MAKEDEV 8
|

.SH NAME
|
||||
MAKEDEV, DESCRIBE \- make/describe device files
|
||||
.SH SYNOPSIS
|
||||
.B MAKEDEV
|
||||
.RB [ \-n ]
|
||||
.IR key " ..."
|
||||
.br
|
||||
.B DESCRIBE
|
||||
.RI [ device "] ..."
|
||||
.SH DESCRIPTION
|
||||
.B MAKEDEV
|
||||
may be used to create the device files normally found in the
|
||||
.B /dev
|
||||
directory. The
|
||||
.I key
|
||||
arguments are simply the names of the devices you want.
|
||||
.B MAKEDEV
|
||||
knows about all supported devices and will create them in the current
|
||||
directory with the proper owner and mode. For many devices
|
||||
.B 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.
|
||||
.PP
|
||||
Call
|
||||
.B MAKEDEV
|
||||
without arguments to see a list of keys that it understands. Then use
|
||||
the
|
||||
.B \-n
|
||||
flag to make the script echo the commands it will execute the next time
|
||||
when you call it without that flag.
|
||||
.PP
|
||||
The special key
|
||||
.B std
|
||||
must be given alone to
|
||||
.BR MAKEDEV .
|
||||
This key will create all standard devices.
|
||||
.PP
|
||||
The command
|
||||
.B DESCRIBE
|
||||
will give you a one-line description of a given device. It will by
|
||||
default list all devices in
|
||||
.BR /dev .
|
||||
.SH "SEE ALSO"
|
||||
.BR dev (4),
|
||||
.BR mknod (8).
|
||||
.SH BUGS
|
||||
.BR MAKEDEV "'s"
|
||||
eagerness to create devices may cause many "File exists" errors from
|
||||
.BR mknod .
