Note that you can unambiguously rebuild a package from a profile
through its locked flake URL and flake attribute, e.g.
```console
# nix build github:edolstra/nix-warez/91f2ffee657bf834e4475865ae336e2379282d34?dir=blender#packages.x86_64-linux.default
```
will build the package with index 1 shown above.
# Description
This command shows what packages are currently installed in a
profile. The output consists of one line per package, with the
following fields:
profile. For each installed package, it shows the following
information:
* An integer that can be used to unambiguously identify the package in
invocations of `nix profile remove` and `nix profile upgrade`.
* `Index`: An integer that can be used to unambiguously identify the
package in invocations of `nix profile remove` and `nix profile
upgrade`.
* The original ("unlocked") flake reference and output attribute path
used at installation time.
* `Flake attribute`: The flake output attribute path that provides the
package (e.g. `packages.x86_64-linux.hello`).
* The locked flake reference to which the unlocked flake reference was
resolved.
* `Original flake URL`: The original ("unlocked") flake reference
specified by the user when the package was first installed via `nix
profile install`.
* The store path(s) of the package.
* `Locked flake URL`: The locked flake reference to which the original
flake reference was resolved.
* `Store paths`: The store path(s) of the package.
