### How can I check if my package already have been uploaded in the binary cache?
|
||||||
|
|
||||||
|
If you provide the `--check-cache-status`, the json will contain a `"isCached"`
|
||||||
|
key in its json, that is true or false based on the status.
|
||||||
|
|
||||||
|
### How can I evaluate nixpkgs?

||||||

|
||||||
|
|
||||||
|
```console
|
||||||
|
$ nix-eval-jobs --force-recurse pkgs/top-level/release.nix
|
||||||
|
```
