Name

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

Synopsis

       nix hash path [option…] paths…

Options

       •  --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).

   Logging-related options
       •  --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          Consider all previously downloaded files out-of-date.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.
