Get a store path from its hash part.

Warning

This program is experimental and its interface is subject to change.

Synopsis

nix store path-from-hash-part [option...] hash-part

Examples

  • Return the full store path with the given hash part:
## nix store path-from-hash-part --store https://cache.nixos.org/ 0i2jd68mp5g6h2sa5k9c85rb80sn8hi9
/nix/store/0i2jd68mp5g6h2sa5k9c85rb80sn8hi9-hello-2.10

Description

Given the hash part of a store path (that is, the 32 characters following /nix/store/), return the full store path. This is primarily useful in the implementation of binary caches, where a request for a .narinfo file only supplies the hash part (e.g. https://cache.nixos.org/0i2jd68mp5g6h2sa5k9c85rb80sn8hi9.narinfo).
