Name
nix hash path - print cryptographic hash of the NAR serialisation of a path
Synopsis
nix hash path [option...] paths...
Options
-
--algohash-algoHash algorithm (
md5,sha1,sha256, orsha512). -
Print the hash in base-16 format.
-
Print the hash in base-32 (Nix-specific) format.
-
Print the hash in base-64 format.
-
--formathash-formatHash format (
base16,nix32,base64,sri). Default:sri. -
--modefile-ingestion-methodHow 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.
-
-
Print the hash in SRI format.
-
--typehash-algoHash algorithm (
md5,sha1,sha256, orsha512).

-
Set the logging verbosity level to 'debug'.
-
--log-formatformatSet the format of log output; one of
raw,internal-json,barorbar-with-logs. -

-
--verbose/-vIncrease the logging verbosity level.
Miscellaneous global options

-
Disable substituters and consider all previously downloaded files up-to-date.
-
--optionname valueSet the Nix configuration setting name to value (overriding
nix.conf). -
Consider all previously downloaded files out-of-date.
