will create <filename>/nix</filename> using <command>sudo</command>,
so make sure you have sufficient rights. (For other installation
methods, see <xref linkend="chap-installation"/>.)</para></listitem>

platform. Associate <literal>application/nix-package</literal> with
the program <command>nix-install-package</command>. A window should
2006-09-29 11:03:16 +00:00
appear asking you whether its okay to install the package. Say
<literal>Y</literal>. The package and all its dependencies will be
installed.</para></listitem>

$ nix-collect-garbage -d</screen>

<!--
The first command deletes old “generations” of your profile (making
2007-12-04 11:42:58 +00:00
rollbacks impossible, but also making the packages in those old
generations available for garbage collection), while the second
command actually deletes them.-->
