`nix-collect-garbage --dry-run` did not previously give any output - it simply
|
||
|
|
exited without even checking to see what paths would be deleted.
|
||
|
|
|
||
|
|
```
|
||
|
|
$ nix-collect-garbage --dry-run
|
||
|
|
$
|
||
|
|
```
|
||
|
|
|
||
|
|
We updated the behaviour of the flag such that instead it prints out how many
|
||
|
|
paths it *would* delete, but doesn't actually delete them.
|
||
|
|
|
||
|
|
```
|
||
|
|
$ nix-collect-garbage --dry-run
|
||
|
|
finding garbage collector roots...
|
||
|
|
determining live/dead paths...
|
||
|
|
...
|
||
|
|
<nix store paths>
|
||
|
|
...
|
||
|
|
2670 store paths deleted, 0.00MiB freed
|
||
|
|
$

|

```
