Warning
This program is experimental and its interface is subject to change.

Synopsis

nix hash path [option…] paths…

--algo hash-algo
Hash algorithm (blake3, 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 (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.

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Consider all previously downloaded files out-of-date.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