💖 KTOBLZCHECK 💖

okay bestie, sit down, hydrate, because we're about to talk about ktoblzcheck from the General Commands Manual — yes that one, the bank-checking icon herself 💅

✨ NAME ✨

ktoblzcheck — Check Account and BLZ (bank routing code) 🏦

🌸 SYNOPSIS 🌸

ktoblzcheck [--returncode] [--file=<datafile>] <bank-id> <account-id>

🦋 DESCRIPTION 🦋

So this manual page is here to briefly document the ktoblzcheck application, and honestly? she's giving useful.

ktoblzcheck is a program that will check a given account and blz for the bank being valid and the account being valid, using some checksum calculations — if those are supported for that particular bank. Not all banks are supported, and that's just the vibe we live with, no cap.

The output is the clear-text name of the bank specified by <bank-id>, plus whether the given <account-id> is a valid account number at this bank. Literally just "here's your bank, here's whether your number slays or not." 💅

🎀 OPTIONS 🎀

  • <bank-id> — This is the Bankleitzahl (bank routing id). Actually — plot twist — it is the account-id of that particular bank at the Deutsche Bundesbank. Yes really, the routing code IS an account id. The way that works is iconic honestly. 👑
  • <account-id> — This is the account number you wish to verify. If the checksum method of the bank specified by the <bank-id> is supported, you will get the account-id verified — i.e. you'll find out if it's a valid account-id at that particular bank. If it's not supported… well. "unknown" era. 🙈
  • --returncode — If given, the result is returned via the returncode and there is no output on the terminal. So like, she goes quiet and speaks in exit codes instead. 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=<datafile> — Specifies the file with the bankdata. You can obtain this file via the internet from the Deutsche Bundesbank at this address:

⚠️ Beware! This page is in German only. Duolingo girlies, this is your moment fr fr. 🇩🇪

💀 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. She's doing her best, okay?? Not every bank made the cut. It's giving limited roster, and we simply must accept that. 😭
