🎀 SYD-SUM(1) 🎀

the general commands manual, bestie ✨

okay so, hi!! you're looking at the man page for syd-sum, one of the little sydbox helper tools 🦋 (yes, the manual name is literally SYD-SUM, section 1, general commands manual, iykyk 💅).

✨ NAME ✨

syd-sum — calculate the checksum of the given file or standard input 💖

🌸 SYNOPSIS 🌸

syd-sum -a alg [-bhx] <file|->

like, that's the whole vibe check right there 🫶

🧚 DESCRIPTION 🧚

so basically: give it a file, and it calculates the checksum of that file. slay. ⭐

only regular files and FIFOs (pipes) may be hashed — that's the rule, no cap 🚫

and if you give it no positional arguments at all, or you pass - as the argument, it calculates the checksum of standard input instead 🌈 (very much main character energy of stdin honestly)

💅 OPTIONS 💅

  • -a alg — the hash algorithm to use, and yes it's required 👑 use -a list to list the available algorithms and their digest sizes. examples include: sha256, sha512, sha3-512, blake2b-256, md5, crc32c ✨
  • -b — binary output 🍓
  • -x — hexadecimal output, which is the default btw 💜
  • -h — display help 🙈

🔥 EXAMPLES 🔥

like, here's how the girlies actually do it:

syd-sum -a sha256 /usr/bin/syd
echo hello | syd-sum -a blake2b-512
syd-sum -a crc32c -b /etc/passwd > /tmp/crc.bin

ate. no crumbs. 💀
