nix hash path - print cryptographic hash of the NAR serialisation of a path

nix hash path [option…] paths…

•
--algo hash-algo
Hash algorithm (md5, sha1, sha256, or sha512).
•
--base16
Print the hash in base-16 format.
•
--base32
Print the hash in base-32 (Nix-specific) format.
•
--base64
Print the hash in base-64 format.
•
--format hash-format
Hash format (base16, nix32, base64, sri). Default: sri.
•
--mode file-ingestion-method
How to compute the hash of the input. One of:
  • nar (the default): Serialises the input as a Nix Archive and passes that to the hash function.
  • flat: Assumes that the input is a single file and directly passes it to the hash function.
•
--sri
Print the hash in SRI format.
•
--type hash-algo
Hash algorithm (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.

•
--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Consider all previously downloaded files out-of-date.
•
