okay bestie, sit down, hydrate, because we're about to talk about hashsum from the General Commands Manual and honestly? it's giving ✨checksum royalty✨.

like yes, it's a lot of flags, but that's just her being versatile 🦋

🎀 DESCRIPTION 🎀

Compute and check message digests. 🧚

that's the vibe. you feed her files, she gives you digests, and she can also check digests for you like the responsible main character she is 👑

💅 OPTIONS 💅

one bullet per flag, no skipping, we don't do that here, we respect the manpage 🫶

• -b, --binary — read in binary mode 🩵
• -c, --check — read hashsums from the FILEs and check them 🔍
• --tag — create a BSD-style checksum ✨
• -t, --text — read in text mode — and this is the default, no cap
• -q, --quiet — don't print OK for each successfully verified file 🤫
• -s, --status — don't output anything at all, the status code shows success
• --strict — exit non-zero for improperly formatted checksum lines 😤
• --ignore-missing — don't fail or report status for missing files 🙈
• -w, --warn — warn about improperly formatted checksum lines ⚠️
• -z, --zero — end each output line with NUL, not newline 💀 (yes really, zero byte, iconic)
• --bits <BITS> — set the size of the output (only for SHAKE) 📏
• --no-names — Omits filenames in the output (option not present in GNU/Coreutils) 🏷️
• --md5 — work with MD5 🔐
• --sha1 — work with SHA1 🔐
• --sha224 — work with SHA224 🔐
• --sha256 — work with SHA256 🔐
• --sha384 — work with SHA384 🔐
• --sha512 — work with SHA512 🔐
• --sha3 — work with SHA3 🔐
• --sha3-224 — work with SHA3-224 🔐
• --sha3-256 — work with SHA3-256 🔐
• --sha3-384 — work with SHA3-384 🔐
• --sha3-512 — work with SHA3-512 🔐
• --shake128 — work with SHAKE128 using BITS for the output size 🌊
• --shake256 — work with SHAKE256 using BITS for the output size 🌊
• --b2sum — work with BLAKE2 🫧
• --b3sum — work with BLAKE3 🫧
• -h, --help — Print help 🆘
• -V, --version — Print version 🏷️

and also:

• [file] — the file, bestie 📁

lowkey reminder: --bits <BITS> is only for SHAKE. don't be out here passing --bits to SHA256 and wondering why she's not answering, she's just not that girl for that flag 😭
