This is used to speed up installations: if you attempt to install something that has already been built and stored into the network cache, Nix can transparently re-use the pre-built store paths. </para> <para> The file at <replaceable>url</replaceable> must be compatible with the files created by <replaceable>nix-push</replaceable>. </para> </refsection> <refsection> <title>Examples</title> <screen> $ nix-pull http://nix.cs.uu.nl/dist/nix/nixpkgs-0.5pre753/MANIFEST</screen> </refsection> </refentry>
