|

This command updates the lock file of a flake (`flake.lock`) so that

`flake.nix`. Existing lock file entries are not updated unless
|

required by a flag such as `--update-input`.

Note that every command that operates on a flake will also update the
|

lock file if needed, and supports the same flags. Therefore,

|

```console
|
||||
# nix flake lock --update-input nixpkgs

# nix build

```

|

```console
|
||||
# nix build --update-input nixpkgs
|
||||
```
|
||||
|
||||
Thus, this command is only useful if you want to update the lock file
|
||||
separately from any other action such as building.

# Description
|
||||
|
||||
This command updates the lock file of a flake (`flake.lock`) so that
|
||||
it contains a lock for every flake input specified in
|
||||
`flake.nix`. Note that every command that operates on a flake will
|
||||
also update the lock file if needed, and supports the same
|
||||
flags. Therefore,
|
||||
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,
|
||||
|
||||
```console
|
||||
# nix flake update --update-input nixpkgs
|
||||
# nix flake update
|
||||
# nix build
|
||||
```
|
||||
|
||||
is equivalent to:
|
||||
|
||||
```console
|
||||
# nix build --update-input nixpkgs
|
||||
# nix build --recreate-lock-file
|
||||
```
|
||||
|
||||
Thus, this command is only useful if you want to update the lock file
|
||||
separately from any other action such as building.
|
||||
|
||||
> **Note**
|
||||
>
|
||||
> This command does *not* update locks that are already present unless
|
||||
> you explicitly ask for it using `--update-input` or
|
||||
> `--recreate-lock-file`. Thus, if the lock file already has locks for
|
||||
> every input, then `nix flake update` (without arguments) does
|
||||
> nothing.
