The output is the clear-text name of the bank specified by \, and whether the given \ is a valid account number at this bank. ## OPTIONS - **\** This is the Bankleitzahl (bank routing id), actually it is the account-id of that particular bank at the Deutsche Bundesbank. - **\** This is the account number you wish to verify. If the checksum method of the bank specified by the \ is supported, you will get the account-id verified, i.e. if it is a valid account-id at that particular bank. - **--returncode** If given, the result is returned via the returncode and no output on the terminal. The following returncodes are possible: 0: account and bank are ok 1: unknown, e.g. checksum not implemented or such 2: account and/or bank not ok 3: bank not found - **--file=\** Specifies the file with the bankdata. This file can be obtained via the internet from the Deutsche Bundesbank on address ``` http://www.bundesbank.de/zahlungsverkehr/zahlungsverkehr_bankleitzahlen_download.php ``` Beware! This page is in German only. ## BUGS No bugs are known at this time. Only certain checksum algorythms are supported as of now, so please don't complain if you always get "unknown" as return value. ## AUTHOR This manual page was written by Jens Gecius \ for the Debian GNU/Linux system.
