# Examples
* Recreate the lock file (i.e. update all inputs) and commit the new
lock file:
```console
# nix flake update
warning: updating lock file '/home/myself/repos/testflake/flake.lock':
• Updated input 'nix':
'github:NixOS/nix/9fab14adbc3810d5cc1f88672fde1eee4358405c' (2023-06-28)
→ 'github:NixOS/nix/8927cba62f5afb33b01016d5c4f7f8b7d0adde3c' (2023-07-11)
• Updated input 'nixpkgs':

# Description
This command recreates the lock file of a flake (`flake.lock`), thus
updating the lock for every unlocked 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,
2020-12-23 14:19:53 +02:00
```console
# nix flake update
2020-12-23 14:19:53 +02:00
# nix build
```
is equivalent to:
```console
# nix build --recreate-lock-file
2020-12-23 14:19:53 +02:00
```
