Information about gc roots can be found in <code>/nix/var/nix/gcroots</code>. The following script demonstrates how this directory can be used to (for example) query the state of manually made result symlinks: | |||
<syntaxhighlight lang="bash">find -H /nix/var/nix/gcroots/auto -type l | xargs -I {} sh -c 'readlink {}; realpath {}; echo'</syntaxhighlight> | |||
This acts a simpler (but faster) version of <code>--print-roots</code> and could be implemented as a bash alias for convenience. | |||
