💖 CRC32C(1) 💖

okay bestie, so this is the manual page for crc32c — like, the whole thing, version 2.8 and everything. buckle up, it's short and it's iconic ✨

🌸 NAME 🌸

crc32c — literally the manual page for crc32c 2.8, no cap

---

🦋 DESCRIPTION 🦋

so here's the vibe check on how you actually run it:

usage: crc32c

       [-h] [-M] [-b BLOCK_SIZE] [-s] [-N] filenames [filenames ...]

what it does? it calculates and prints crc32c on input file(s) 💅 that's the whole job. it's giving checksum main character energy.

🎀 positional arguments 🎀

• filenames — the input file(s), bestie. yes you can give it more than one, it says [filenames ...] for a reason 🫶

💅 options 💅

• -h, --help — shows this help message and then exits, like a polite little icon 👑

🧚 I/O options 🧚

• -M, --disable-mmap — tells it to avoid reading the file with mmap. like, don't do the mmap thing, do it the other way. lowkey niche but we love options 💜
• -b BLOCK_SIZE, --block-size BLOCK_SIZE — sets the block size used for iterative reading. so like, how big each chunk is 🌈

⭐ Formatting options ⭐

• -s, --show-speed — reports checksumming speed on each file. obsessed, it's literally telling you how fast it ate 🔥
• -N, --hide-filename — don't print the filename in the result. just the checksum, mystery edition 🙈

🍓 SEE ALSO 🍓

so the full documentation for crc32c is maintained as a Texinfo manual. if the info and crc32c programs are properly installed at your site, then running

info crc32c

should give you access to the complete manual ✨ iykyk 🦋

fr fr, that's the whole page — no hidden lore, no surprise flags. what you see is what you get 💖

and that's a wrap, bestie 🎀 this was crc32c version 2.8, dated October 2025 — go checksum something and slay 💅👑
