# Examples
|
|
|
|
* Download a file to the Nix store:
|
|
|
|
```console
|
|
# nix store prefetch-file https://releases.nixos.org/nix/nix-2.3.10/nix-2.3.10.tar.xz
|
|
Downloaded 'https://releases.nixos.org/nix/nix-2.3.10/nix-2.3.10.tar.xz' to
|
|
'/nix/store/vbdbi42hgnc4h7pyqzp6h2yf77kw93aw-source' (hash
|
|
'sha256-qKheVd5D0BervxMDbt+1hnTKE2aRWC8XCAwc0SeHt6s=').
|
|
```
|
|
|
|
* Download a file and get the SHA-512 hash:
|
|
|
|
```console
|
|
# nix store prefetch-file --json --hash-type sha512 \
|
|
https://releases.nixos.org/nix/nix-2.3.10/nix-2.3.10.tar.xz \
|
|
| jq -r .hash
|
|
sha512-6XJxfym0TNH9knxeH4ZOvns6wElFy3uahunl2hJgovACCMEMXSy42s69zWVyGJALXTI+86tpDJGlIcAySEKBbA==

# Description
|
|
|
|
This command downloads the file *url* to the Nix store. It prints out
|
|
the resulting store path and the cryptographic hash of the contents of
|
|
the file.
|
|
|
|
The name component of the store path defaults to the last component of
|
|
*url*, but this can be overridden using `--name`.
