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: • --arg name expr Pass the value expr as the argument name to Nix functions. • --argstr name string Pass the string string as the argument name to Nix functions. • --eval-store store-url The Nix store to use for evaluations. • --impure Allow access to mutable paths and repositories. • --include / -I path Add path to the list of locations used to look up <...> file names. • --override-flake original-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-from flake-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-input input-path flake-url Override a specific flake input (e.g. dwarffs/nixpkgs). This implies --no-write-lock- file. nix3-flake-update(1)
