NAME
putdgrp - edits 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(s) to the group definition. When invoked with both arguments and the -d option, the command deletes the device name(s) 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. OPTIONS
The following options are supported: -d Delete the group or, if used with device, delete the device from a group definition. OPERANDS
The following operands are supported: dgroup Specify a device group name. device Specify the pathname or alias of the device that is to be added to, or deleted from, the device group. EXIT STATUS
The following exit values are returned: 0 Successful completion. 1 Command syntax was incorrect, an invalid option was used, or an 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. EXAMPLES
Example 1 Adding a new device group. The following example adds a new device group: example# putdgrp floppies Example 2 Adding a device to a device group. The following example adds a device to a device group: example# putdgrp floppies diskette2 Example 3 Deleting a device group. The following example deletes a device group: example# putdgrp -d floppies Example 4 Deleting a device from a device group. The following example deletes a device from a device group: example# putdgrp -d floppies diskette2 FILES

NAME
getdgrp - lists device groups which contain devices that match criteria SYNOPSIS
/usr/sbin/getdgrp [-ael] [criteria...] [dgroup...] DESCRIPTION
getdgrp generates a list of device groups that contain devices matching the given criteria. The criteria is given in the form of expres- sions. OPTIONS
The following options are supported: -a Specifies that a device must match all criteria to be included in the list generated by this command. The option has no effect if no criteria are defined. -e Specifies that the list of device groups on the command line should be excluded from the list generated by this command. Without the -e option the named device groups are included in the generated list. The flag has no effect if no devices are defined. -l Specifies that all device groups (subject to the -e option and the dgroup list) should be listed even if they contain no valid device members. This option has no affect if criteria is specified on the command line. OPERANDS
The following operands are supported: criteria Defines criteria that a device must match before a device group to which it belongs can be included in the generated list. Specify criteria as an expression or a list of expressions which a device must meet for its group to be included in the list generated by getdgrp. If no criteria are given, all device groups are included in the list. Devices must satisfy at least one of the criteria in the list. However, the -a option can be used to define that a "logi- cal and" operation should be performed. Then, only those groups containing devices which match all of the criteria in a list will be included. There are four possible expressions types which the criteria specified in the criteria argument may follow: attribute=value Selects all device groups with a member whose attribute attribute is defined and is equal to value. attribute!=value Selects all device groups with a member whose attribute attribute is defined and does not equal value. attribute:* Selects all device groups with a member which has the attribute attribute defined. attribute!:* Selects all device groups with a member which does not have the attribute attribute defined. See putdev(1M) for a complete listing and description of available attributes. dgroup Defines a set of device groups which should be included in or excluded from the generated list. Device groups that are defined and which contain devices matching the criteria are included. If the -e option is used, this list defines a set of device groups to be excluded. When the -e option is used and crite- ria is also defined, the generated list will include device groups containing devices which match the criteria and are not in the command line list. EXIT STATUS
The following exit values are returned: 0 Successful completion of the task. 1 Command syntax was incorrect, invalid option was used, or an internal error occurred. 2 Device table or device group table could not be opened for reading. FILES
