---

like. look at her. so many little flags. main character energy fr 🫶

---

🦋 DESCRIPTION 🦋

print or check the BLAKE2b checksums 💖 that's the whole job. she prints them, she checks them, she slays. no notes.

---

✨ OPTIONS ✨

• -c, --check — reads the checksums out of the *FILE*s and checks them. the "wait, is this file still okay??" era 🕵️♀️
• -w, --warn — gives you a lil heads-up about checksum lines that are improperly formatted. not me snitching on bad formatting 👀
• --status — outputs literally nothing, and lets the status code do the talking. success shows up as an exit code and nothing else. silent, mysterious, iconic 💀
• --quiet — don't print OK for every single file that verified successfully. she's not gonna hype you up for each one, she trusts you 💜
• --ignore-missing — missing files get no failure and no status report. if it's not there, we simply don't talk about it 🙈
• --strict — exits non-zero for improperly formatted checksum lines. strict queen. she has STANDARDS 👑
• -l, --length — digest length in bits; must not exceed the max size, and must be a multiple of 8 for blake2b; must be 224, 256, 384, or 512 for sha2 or sha3 🌈
• --tag — create a BSD style checksum 🎀
• -t, --text — read in text mode, and yes, that's the default. the classic. the OG 🍓
• -z, --zero — end each output line with NUL, not newline, and disable file name escaping. nul-terminated girlies rise up ⭐
• -h, --help — print help 🧚
• -V, --version — print version 💖

---

🌟 VERSION 🌟

v(uutils coreutils) 0.7.0

---

lowkey a note for you bestie: --status means no output at all — the status code is the entire message. and --strict will make improperly formatted lines count as a non-zero exit. read them carefully, no cap 💅
