Name
nix flake update - update flake lock file
Synopsis
nix flake update [option...] flake-url
Examples
-
Recreate the lock file (i.e. update all inputs) and commit the new lock file:
# nix flake update * Updated 'nix': 'github:NixOS/nix/9fab14adbc3810d5cc1f88672fde1eee4358405c' -> 'github:NixOS/nix/8927cba62f5afb33b01016d5c4f7f8b7d0adde3c' * Updated 'nixpkgs': 'github:NixOS/nixpkgs/3d2d8f281a27d466fa54b469b5993f7dde198375' -> 'github:NixOS/nixpkgs/a3a3dda3bacf61e8a39258a0ed9c924eeca8e293' … warning: committed new revision '158bcbd9d6cc08ab859c0810186c1beebc982aad'
Description
This command recreates the lock file of a flake (flake.lock), thus
updating the lock for every mutable input (like nixpkgs) to its
current version. This is equivalent to passing --recreate-lock-file
to any command that operates on a flake. That is,
# nix flake update
# nix build
is equivalent to:
# nix build --recreate-lock-file
Options
Common evaluation options:
-
--argname expr
Pass the value expr as the argument name to Nix functions. -
--argstrname string
Pass the string string as the argument name to Nix functions. -
--eval-storestore-url
The Nix store to use for evaluations. -
--impure
Allow access to mutable paths and repositories. -
--include/-Ipath
Add path to the list of locations used to look up<...>file names. -
--override-flakeoriginal-ref resolved-ref
Override the flake registries, redirecting original-ref to resolved-ref.
Common flake-related options:
-
--commit-lock-file
Commit changes to the flake's lock file. -
--inputs-fromflake-url
Use the inputs of the specified flake as registry entries. -
--no-registries
Don't allow lookups in the flake registries. This option is deprecated; use--no-use-registries. -
--override-inputinput-path flake-url
Override a specific flake input (e.g.dwarffs/nixpkgs). This implies--no-write-lock-file.
