Description
Item | Description |
---|---|
-a | Adds an entry to the system configuration database. The -a flag must be used with either the -i or -D flag. |
-B FileName | Restores the /etc/resolv.conf file from the file specified by the FileName variable. |
-b | Creates
the system configuration database, using the /etc/resolv.conf.sv file.
If the /etc/resolv.conf.sv file does not exist, an error is
returned. Note: The /etc/resolv.conf.sv file is not shipped
with the system. You have to create the file before the -b flag
will work.
|
-C | Changes the search list in the /etc/resolv.conf file. |
-c DomainName | Changes the domain name in the system configuration database. |
-D | Indicates that the command deals with the domain name entry. |
-d | Deletes an entry in the system configuration database. It must be used with the -i IPAddress flag or the -n flag. The -i flag deletes a name server entry. The -n flag deletes the domain name entry. |
-E FileName | Renames the system configuration database file, so you can stop using a name server. The /etc/resolv.conf file is moved to the file specified by the FileName variable. |
-e | Moves the /etc/resolv.conf file to the /etc/resolv.conf.sv file, preventing use of a name server. |
-I | (Uppercase i) Specifies that the -s flag or -X flag should print all name server entries. |
-i IPAddress | Indicates that the command deals with a name server entry. Use dotted decimal format for the given IP address. |
-l | (Lowercase L) Specifies that the operation is on the search list. Use this flag with the -d and -s flag. |
-n | Specifies that the operation is on the domain name. Use this flag with the -d flag and the -s flag. |
-S SearchList | Changes the search list in the system configuration database. |
-s | Shows all domain and name server entries in the configuration system database. If you use the -i flag, the namerslv command shows all name server entries. If you use the -n flag, the namerslv command shows the domain name entry found in the database. |
-X | Deletes all entries in the database. Use the -I flag with this flag to delete all name server entries. |
-Z | Generates the output of the query in colon format. This flag is used when the namerslv command is called from the SMIT usability interface. |
