This program is experimental and its interface is subject to change. So like... don't build your whole personality around it, okay? 💀

✨ Name ✨

nix hash path — print the cryptographic hash of the NAR serialisation of a path 🎀

(yes it's nix3-hash-path(1) from the General Commands Manual, we're getting into it 💅)

🌸 Synopsis 🌸

nix hash path [option…] paths…

💖 Options 💖

  • --algo hash-algo — which hash algorithm you're vibing with: blake3, md5, sha1, sha256, or sha512.
  • --base16 — print that hash in base-16 format.
  • --base32 — print that hash in base-32 (Nix-specific) format.
  • --base64 — print that hash in base-64 format.
  • --format hash-format — the hash format, one of base16, nix32, base64, sri. Default: sri.
  • --mode file-ingestion-method — how to actually compute the hash of your input. Pick one:
    • nar (the default): serialises the input as a Nix Archive and hands that over to the hash function.
    • flat: assumes the input is a single file and passes it straight to the hash function.
  • --sri — print the hash in SRI format.
  • --type hash-algo — hash algorithm again, bestie: blake3, md5, sha1, sha256, or sha512.
  • --debug — set the logging verbosity level to ‘debug’.
  • --log-format format — set the format of log output; one of raw, internal-json, bar or bar-with-logs.
  • --print-build-logs / -L — print full build logs on standard error.
  • --quiet — decrease the logging verbosity level.
  • --verbose / -v — increase the logging verbosity level.

🌈 Miscellaneous global options 🌈

  • --help — show usage information.
  • --offline — disable substituters and consider all previously downloaded files up-to-date.
  • --option name value — set the Nix configuration setting name to value (overriding nix.conf).
  • --refresh — consider all previously downloaded files out-of-date.
  • --version — show version information.
📝 Note — see man nix.conf for overriding configuration settings with command line flags. iykyk 💜
