msf(8)

NAME

msf - simplified make special file

SYNTAX

/etc/msf [ -f ] [ -r ] [ -t ] device [ -c n ] unit [ ttynn ]
/etc/msf

DESCRIPTION

The msf program, invoked with a single command sequence, makes or removes the special files for a specified device.

The specified device argument names the generic name of the device for which special files are to be made or removed. For example, because msf uses the generic name instead of the ULTRIX-11 mnemonic, you would specify rp06 and not hp.

The specified unit argument has two possible meanings. First, for pseudo TTYs, MAUS, or single line units (DL11/KL11), unit specifies the number of lines or MAUS segments. In this case, one /dev/ttynn or a pseudo TTY pair will be made or removed for each line. Second, for all other devices, unit specifies the physical unit number. In either case, however, to affect all units or lines, you can specify the word "all." Because a large number of special files potentially could be made or removed, uses this argument with caution. For example, you would make or remove the special files for 64 units, 6 files each, if you specify:

tm03 all

The optional ttynn argument specifies the starting TTY number for communications devices: first /dev/ttynn file for that device. The default starting TTY number is zero. For example, the following command sequence makes 16 special files (/dev/tty16 through /dev/tty31) for DH11, unit 0:

/etc/msf dh11 0 tty16

If both KL and DL devices are present, you can group them together and make or remove their special files with a single command sequence. For example, the following command sequence make the special files for 3 KLs and 4DLs, starting at TTY number zero:

/etc/msf dl11 7 tty00

Specifying no arguments invokes msf in interactive mode. In this mode, msf prompts for the device name and all other required information, and displays on-line help information.

OPTIONS

-c Specifies the MSCP or MASSBUS disk controller number (next argument). The default controller number is zero. The MSCP/MASSBUS controller number is determined by the order in which the controllers were specified during the system generation: the first controller is zero, the second one, the third two, and so on. The controller numbers are grouped by type: MSCP controllers in one and MASSBUS controllers in another.

-f Makes or removes the special files for the specified disk partition (next argument). You can specify a single partition number (0-7) or, to affect all partitions, the word “all”. Normally, msf uses the information listed in the device table and makes or removes the special files only for the partitions actually used by that disk.

-h Displays the on-line help message.

-r Removes special files for the specified device.

-t Displays an information table listing the names of all devices for which msf can create special files.
