jblob	--dataset | -d	dataset_acronym	[ options ]
jblob	--help
jblob	--version

The following options are supported:

--config	file	Read username and password information from file instead of ~/.netrc.
--dateext		Append timestamp(s) to filename instead of record number(s). Works only for datasets with a "calendrical" temporal structure.
--dir	directory	The transferred dataset will be placed in the specified directory.
--file	filename	The transferred dataset will be given the specified name instead of datasetname_rmin-rmax.
--password	password	Use password for database login. Works only in conjunction with --username.
--quiet		Quiet operation. No output except error messages.
--rmax	number	Last record to transfer. If omitted, the transfer will end with the last available record.
--rmin	number	First record to transfer. If omitted, the transfer will start with the first available record.
--tmax	date	Last date to transfer. The standard date format is yyyy-mm-ddThh:mm, however unnecessary parts may be omitted (i.e. yyyy-mm is sufficient when working with monthly data). The minimum required format can be viewed with the jmeta -showtime command.
--tmin	date	First date to transfer. The standard date format is yyyy-mm-ddThh:mm, however unnecessary parts may be omitted (i.e. yyyy-mm is sufficient when working with monthly data). The minimum required format can be viewed with the jmeta -showtime command.
--username	username	Use username for database login. Works only in conjuction with --password.

By default the program tries to read the username and password information from the ~/.netrc file. To utilize this you must add an entry for machine 'cera' to your .netrc file (i.e. machine cera login your_username password your_password). Alternatively you can specify a configuration file from where the login information will be read by using the --config option. This configuration file must follow the same syntax as the .netrc file. As a last resort you can provide username and password with the --username and --password options.

0	Success
1	Unspecified error	Please check program output for additional messages (i.e. do not use the -quiet option).
3	Invalid dataset name	The requested dataset name is doesn't exist in the database.
4	Invalid dataset id	The requested dataset id doesn't exist in the database.
5	Insufficient permission to dataset	You do not have the neccessary permission to access the requested dataset. Please contact data@dkrz.de for further assistance.
8	I/O error	An I/O error was encountered during the data transfer.
12	Temporal structure not supported for tmin/tmax selection	The selected dataset cannot be downloaded by selecting start and end dates, please use selection by record numbers (--rmax, --rmin) instead.
13	Selected start/end record/time outside of datasets coverage.	The supplied rmin/rmax/tmin/tmax value(s) are outside of the dataset's coverage. Check coverage with the 'jmeta --showtime' command.
14	Dataset is empty (data_size = 0)	Please contact data@dkrz.de for further information.
