Examples

• Download a tarball and unpack it:

  # nix store prefetch-tarball https://cdn.kernel.org/pub/linux/kernel/v5.x/linux-5.10.5.tar.xz
  Downloaded 'https://cdn.kernel.org/pub/linux/kernel/v5.x/linux-5.10.5.tar.xz'
  to '/nix/store/sl5vvk8mb4ma1sjyy03kwpvkz50hd22d-source' (hash
  'sha256-3XYHZANT6AFBV0BqegkAZHbba6oeDkIUCDwbATLMhAY=').
  

• Download a tarball and unpack it, unless it already exists in the Nix store:

  # nix store prefetch-tarball https://cdn.kernel.org/pub/linux/kernel/v5.x/linux-5.10.5.tar.xz \
      --expected-hash sha256-3XYHZANT6AFBV0BqegkAZHbba6oeDkIUCDwbATLMhAY=
  

Description

This command downloads a tarball or zip file from url, unpacks it, and adds the unpacked tree to the Nix store. It prints out the resulting store path and the NAR hash of that store path.

The name component of the store path defaults to source, but this can be overriden using --name.
