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

Synopsis
       nix hash path [option<?>] paths<?>

Options
       o  --algo hash-algo

          Hash algorithm (md5, sha1, sha256, or sha512).

       o  --base16

          Print the hash in base-16 format.

       o  --base32

          Print the hash in base-32 (Nix-specific) format.

       o  --base64

          Print the hash in base-64 format.

       o  --format hash-format

          Hash format (base16, nix32, base64, sri). Default: sri.

       o  --mode file-ingestion-method

          How to compute the hash of the input.  One of:

          o  nar (the default): Serialises the input as an archive (following
             the Nix Archive Format) and passes that to the hash function.

          o  flat: Assumes that the input is a single file and directly passes
             it to the hash function;

       o  --sri

          Print the hash in SRI format.

       o  --type hash-algo

          Hash algorithm (md5, sha1, sha256, or sha512).

   Logging-related options
       o  --debug

          Set the logging verbosity level to `debug'.

       o  --log-format format

          Set the format of log output; one of raw, internal-json, bar or
          bar-with-logs.

       o  --print-build-logs / -L

          Print full build logs on standard error.

       o  --quiet

          Decrease the logging verbosity level.

       o  --verbose / -v

          Increase the logging verbosity level.

   Miscellaneous global options
       o  --help

          Show usage information.

       o  --offline

          Disable substituters and consider all previously downloaded files
          up-to-date.

       o  --option name value

          Set the Nix configuration setting name to value (overriding
          nix.conf).

       o  --refresh

          Consider all previously downloaded files out-of-date.

       o  --version

          Show version information.

          Note

          See man nix.conf for overriding configuration settings with command
          line flags.
