The fnattr command is for updating and examining attributes associated with an FNS named object. There are four uses for this command: add an attribute or value, delete an attribute or value, modify an attribute's value, and list the contents of an attribute.
The options for adding, modifying, and deleting attributes and their values can be combined in the same command line. The modifications will be executed in the order that they are specified.
Any unsuccessful modification will abort all subsequent modifications specified in the command line; any modifications already carried out will remain. The unsuccessful modifications are displayed as output of fnattr.
Add an attribute or add a value to an attribute associated with object named by composite_name. identifier is the identifier of the attribute to manipulate; its format is FN_ID_STRING unless the -O or -U option is given. value . . . represents the attribute values to add. The attribute syntax used for storing value is fn_attr_syntax_ascii.
Consult the authoritative source to get attribute information.
Delete attributes associated with object named by composite_name. If identifier is not specified, all attributes associated with the named object are deleted. If identifier is specified without accompanying values (value . . . ), the entire attribute identified by identifier is removed. If individual attribute values (value . . . ) are specified, then only these are removed from the attribute. Removal of the last value of an attribute entails removal of the attribute as well. The format of identifier is FN_ID_STRING unless the -O or -U option is given.
If the composite name is bound to an XFN link, manipulate the attributes associated with the object pointed to by the link. If -L is not used, the attributes associated with the XFN link are manipulated.
Modify the values of the attribute identified by identifier associated with the object named by composite_name. old_value is replaced by new_value in the specified attribute. Other attributes and values associated with composite_name are not affected. The format of identifier is FN_ID_STRING unless the -O or -U option is given.
The format of identifier is FN_ID_ISO_OID_STRING, an ASN.1 dot-separated integer list string.
Add in supersede mode. If an attribute with the same identifier as identifier already exists, remove all its values, and replace with value. If this option is omitted, the resulting values for the specified attribute is a union of the existing values and value.
The format of identifier is FN_ID_DCE_UUID, a DCE UUID in string form.
The -a option is used for adding attributes and values. This following command replaces the value of the shoesize attribute of user/jane with the value 7.5:
eg% fnattr user/jane -as shoesize 7.5
The following command adds the value Chameleo to the project attribute of user/jane:
eg% fnattr user/jsmith -a project Chameleo
The -d option is used for deleting attributes and values. The following command deletes all the attributes associated with user/jane:
eg% fnattr user/jane -d
The following command deletes the attribute shoesize associated with user/jane:
eg% fnattr user/jane -d shoesize
The following command deletes the attribute value old_project from the projects attribute associated with user/jane:
eg% fnattr user/jane -d projects old_project
The -m option is for modifying an attribute value. The following command replaces the value Chameleo by Dungeon in the projects attribute associated with user/jsmith:
eg% fnattr user/jsmith -m projects Chameleo Dungeon
The following command is an example of unsuccessful modification attempts. The user executing this command does not have permission to update user/jane's attributes but is allowed to add new attributes. Executing the command will add the attribute hatsize but will not delete shoesize or modify dresssize because -d shoesize will fail and cause the command to stop:
eg% fnattr user/jane -a hatsize medium -d shoesize -m dresssize 5 6
No options are required to list attributes and their values. The following command lists all the attributes associated with user/jane:
eg% fnattr user/jane
The following command lists the values of the project attribute of user/jane:
eg% fnattr user/jane project
The following command lists the values of the project and shoesize attributes of user/jane:
eg% fnattr user/jane project shoesize
See attributes(5) for descriptions of the following attributes:
|ATTRIBUTE TYPE||ATTRIBUTE VALUE|
Built-in attributes, such as onc_unix_passwd for users, cannot be updated using the fnattr command. Their contents are affected by updates to the underlying naming service, such as NIS+ or NIS.
