The syntax for changing a table entry's owner uses an indexed entry to identify the entry, as shown below:
nischown new-owner [column=value,...],tablename
new-owner is the fully qualified user ID of the object's new owner.
column is the name of the column whose value will identify the particular entry (row) whose owner is to be changed.
value is the data value that identified the particular entry (row) whose owner is to be changed.
... indicates that you can specify ownership changes for multiple entries.
tablename is the fully qualified name of the tables containing the entry whose owner is to be changed.
Be sure to append the domain name to both the new owner name and the table name.
The example below changes the owner of an entry in the hosts table of the doc.com. domain to takeda whose home domain is doc.com. The entry is the one whose value in the name column is virginia.
client% nischown takeda.doc.com. '[name=virginia],hosts.org_dir.doc.com.'
