Usage: $(basename $0) [Options]
|
||||
|
||||
Script removes a domain from bind (slave) nameservice.
|
||||
|
||||
If running in a terminal and NOT '-q' is used, script acts in
|
||||
interactive mode. Script uses defaults either reading from file
|
||||
${conf_file}, or if not present, bei hardcoded default settings.
|
||||
You will be asked to confirm or override the default setting.
|
||||
|
||||
If not running in a terminal (i.e. used as cronjob) or flag '-q' (and
|
||||
within '-d') is set, all configurations are read from file '${conf_file}'.
|
||||
|
||||
|
||||
Options:
|
||||
|
||||
-d <domain>
|
||||
The name of the domain, which is requested for deletion.
|
||||
|
||||
-h
|
||||
Prints this help.
|
||||
|
||||
-q
|
||||
Be quiet. If '-q' is used, also a domain must be given using
|
||||
parameter '-d'.
