@ -8,41 +8,10 @@ Most Nix commands interpret the following environment variables:
- [`NIX_PATH`]{#env-NIX_PATH}\
A colon-separated list of directories used to look up Nix
expressions enclosed in angle brackets (i.e., `<path>`). For
instance, the value
/home/eelco/Dev:/etc/nixos
will cause Nix to look for paths relative to `/home/eelco/Dev` and
`/etc/nixos`, in this order. It is also possible to match paths
against a prefix. For example, the value
nixpkgs=/home/eelco/Dev/nixpkgs-branch:/etc/nixos
will cause Nix to search for `<nixpkgs/path>` in
`/home/eelco/Dev/nixpkgs-branch/path` and `/etc/nixos/nixpkgs/path`.
If a path in the Nix search path starts with `http://` or
`https://`, it is interpreted as the URL of a tarball that will be
downloaded and unpacked to a temporary location. The tarball must
consist of a single top-level directory. For example, setting
`NIX_PATH` to
nixpkgs=https://github.com/NixOS/nixpkgs/archive/master.tar.gz
tells Nix to download and use the current contents of the
`master` branch in the `nixpkgs` repository.
The URLs of the tarballs from the official nixos.org channels (see
[the manual for `nix-channel`](nix-channel.md)) can be abbreviated
as `channel:<channel-name>`. For instance, the following two
values of `NIX_PATH` are equivalent:
nixpkgs=channel:nixos-21.05
nixpkgs=https://nixos.org/channels/nixos-21.05/nixexprs.tar.xz
The Nix search path can also be extended using the `-I` option to
many Nix commands, which takes precedence over `NIX_PATH`.
expressions enclosed in angle brackets (i.e., `<path>`),
e.g. `/home/eelco/Dev:/etc/nixos`. It can be extended using the
`-I` option. For more information about the semantics of the Nix
search path, see the documentation for `-I`.

Normally, the Nix store directory (typically `/nix/store`) is not
