The command <command>nix-collect-garbage</command> determines
|
||
|
|
the paths in the Nix store that are garbage, that is, not
|
||
|
|
reachable from outside of the store. These paths can be safely
|
||
|
|
deleted without affecting the integrity of the system.

Causes the set of <emphasis>reachable</emphasis> paths to

<para>

Causes <command>nix-collect-garbage</command> not to
|
||
|
|
follow successor relations. By default, if a derivation
|
||
|
|
store expression is reachable, its successor (i.e., a
|
||
|
|
closure store expression) is also considered to be
|
||
|
|
reachable. This option is always safe, but garbage
|
||
|
|
collecting successors may cause undesirable rebuilds later
|
||
|
|
on.

To delete all unreachable paths, do the following:

|

|
|
<screen>
|

|
|
$ nix-collect-garbage | xargs nix-store --delete</screen>
