✨ NAME ✨

codes_bufr_filter — the manual page for codes_bufr_filter. that's it, that's the name, she's a little meta like that 💅

🌸 DESCRIPTION 🌸

🫶 NAME 🫶

bufr_filter — yes bestie, there's a whole second NAME hiding inside the DESCRIPTION, iconic behaviour, we love a nested reveal 💀

💜 DESCRIPTION (for real this time) 💜

Apply the rules defined in rules_file to each BUFR message in the BUFR files you hand over as arguments. every single one, no skipping, she's thorough 🦋

And listen — if you pass - (a single dash) as the rules_file, the rules get read from standard input. that's the plot twist right there, periodt 🎀

🌈 USAGE 🌈

bufr_filter [options] rules_file bufr_file bufr_file ...

that's the shape of it: options, then your rules file, then as many BUFR files as your heart desires 💫

👑 OPTIONS 👑

• -f — Force. literally force the execution not to fail on error. she's pushing through, no cap 🔥
• -o output_file — Output gets written to output_file. but here's the tea: if an output file is required and you did not use -o, the output goes to filter.out instead. default behaviour, we don't make the rules 🙈
• -V — Print version. show me the numbers, bestie ⭐
• -g — Copy GTS header. yes queen, bring the header along 🎀
• -7 — Does not fail when the message has wrong length. she's forgiving like that 💅
• -v — Verbose. tell me everything, I'm sat 🍓
• -h — Display this help text and exit. the classic escape hatch 💖
