👑 WHIRLPOOLSUM(1) — the User Commands glow-up 💅

okay bestie so this is whirlpoolsum, and it lives in the User Commands section of your manual, which is basically the VIP lounge of man pages. pull up a chair, we're doing checksums 💖

✨ NAME ✨

whirlpoolsum — compute and check WHIRLPOOL message digest. that's it, that's the whole vibe. she computes, she checks, she serves 🦋

🌸 SYNOPSIS 🌸

whirlpoolsum [OPTION]... [FILE]...

💜 DESCRIPTION 💜

So here's the tea: whirlpoolsum prints or checks WHIRLPOOL (512-bit) checksums. And if you hand her no FILE at all, or you hand her a FILE that's literally just -? she reads standard input instead. generous queen behavior 🫶

  • -b, --binary — read in binary mode 🌈
  • -c, --check — read WHIRLPOOL sums from the FILEs and check them 👀
  • --tag — create a BSD-style checksum, always in binary mode, no negotiation ✨
  • -t, --text — read in text mode, which is the default btw 🎀
note, and this is important: there is no difference between binary and text mode option on a GNU system. they're the same girl, different outfit 💅

🧚 the check-only girlies 🧚

okay so the following three options are useful only when verifying checksums (yes bestie, three, even though there's four of them listed — I don't make the rules, I just report them 💀):

  • --quiet — don't print OK for each successfully verified file, we stay humble 🙈
  • --status — don't output anything at all; the status code shows success. silent but lethal 💀
  • -w, --warn — warn about improperly formatted checksum lines 🚨
  • --strict — with --check, exit non-zero for any invalid input. zero tolerance, periodt 👑

🎀 the rest of the menu 🎀

  • --test — invoke the Whirlpool API test function and exit. it's giving QA era 🔥
  • --help — display this help and exit 🌟
  • --version — output version information and exit ⭐

The sums are computed as described in the official WHIRLPOOL specs — no improvisation, we respect the source material 📜

When checking, the input should be a former output of this program. iykyk — you can't just feed her anything, she needs her own handwriting back 🥺

The default mode is to print a line with checksum, a character indicating input mode ('*' for binary, space for text), and name for each FILE. three little pieces, all iconic, all necessary 💖
