nix3-hash-path(1)	    General Commands Manual	     nix3-hash-path(1)

	      Warning
	      This  program  is	 experimental <../../development/experimental-
	      features.md#xp-feature-nix-command> and its interface is subject
	      to change.

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

Synopsis
       nix hash	path [option...] paths...

Options
       •  --algo <#opt-algo> hash-algo

	  Hash algorithm (blake3, md5, sha1, sha256, or	sha512).

       •  --base16 <#opt-base16>

	  Print	the hash in base-16 format.

       •  --base32 <#opt-base32>

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

       •  --base64 <#opt-base64>

	  Print	the hash in base-64 format.

       •  --format <#opt-format> hash-format

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

       •  --mode <#opt-mode> file-ingestion-method

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

	  •  nar  (the	default):  Serialises  the  input  as  a  Nix  Archive
	     <../../store/file-system-object/content-address.md#serial-nix-
	     archive> and passes that to the hash function.

	  •  flat: Assumes that	the input is a single file and directly	passes
	     <../../store/file-system-object/content-address.md#serial-flat>
	     it	to the hash function.

       •  --sri	<#opt-sri>

	  Print	the hash in SRI	format.

       •  --type <#opt-type> hash-algo

	  Hash algorithm (blake3, md5, sha1, sha256, or	sha512).

   Logging-related options
       •  --debug <#opt-debug>

	  Set the logging verbosity level to `debug'.

       •  --log-format <#opt-log-format> format

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

       •  --print-build-logs <#opt-print-build-logs> / -L

	  Print	full build logs	on standard error.

       •  --quiet <#opt-quiet>

	  Decrease the logging verbosity level.

       •  --verbose <#opt-verbose> / -v

	  Increase the logging verbosity level.

   Miscellaneous global	options
       •  --help <#opt-help>

	  Show usage information.

       •  --offline <#opt-offline>

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

       •  --option <#opt-option> name value

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

       •  --refresh <#opt-refresh>

	  Consider all previously downloaded files out-of-date.

       •  --version <#opt-version>

	  Show version information.

	  Note
