putdgrp(1M)                    DG/UX 5.4R3.00                    putdgrp(1M)


NAME
       putdgrp - edit device group table

SYNOPSIS
       putdgrp [-d] dgroup [device [...]]

DESCRIPTION
       putdgrp modifies the device group table.  It performs two kinds of
       modification.  It can modify the table by creating a new device group
       or removing a device group.  It can also change group definitions by
       adding or removing a device from the group definition.

       When the command is invoked with only a dgroup specification, the
       command adds the specified group name to the device group table if it
       does not already exist.  If the -d option is also used with only the
       dgroup specification, the command deletes the group from the table.

       When the command is invoked with both a dgroup and a device
       specification, it adds the given device name (or names) to the group
       definition.  When invoked with both arguments and the -d option, the
       command deletes the device name (or names) from the group definition.

       When the command is invoked with both a dgroup and a device
       specification and the device group does not exist, it creates the
       group and adds the specified devices to that new group.

       The options and arguments for this command are:

       -d        Deletes the group or, if used with device, the device from
                 a group definition.

       dgroup    Specifies a device group name.

       device    Specifies the pathname or alias of the device that is to
                 added to or deleted from the device group.

DIAGNOSTICS
       The command will exit with one of the following values:

       0 = successful completion of the task.

       1 = command syntax incorrect, invalid option used, or internal error
           occurred.

       2 = device group table could not be opened for reading or a new
           device group table could not be created.

       3 = if executed with the -d option, indicates that an entry in the
           device group table for the device group dgroup does not exist and
           so cannot be deleted.  Otherwise, indicates that the device group
           dgroup already exists and cannot be added.

       4 = if executed with the -d option, indicates that the device group
           dgroup does not have as members one or more of the specified

           devices.  Otherwise, indicates that the device group dgroup
           already has one or more of the specified devices as members.

EXAMPLE
       To add a new device group:
            putdgrp floppies
       To add a device to a device group:
            putdgrp floppies diskette2
       To delete a device group:
            putdgrp -d floppies
       To delete a device from a device group:
            putdgrp -d floppies diskette2
