# Examples
|
|
|
|
* Get the build log of GNU Hello:
|
|
|
|
```console
|
|
# nix log nixpkgs#hello
|
|
```
|
|
|
|
* Get the build log of a specific store path:
|
|
|
|
```console
|
|
# nix log /nix/store/lmngj4wcm9rkv3w4dfhzhcyij3195hiq-thunderbird-52.2.1
|
|
```
|
|
|
|
* Get a build log from a specific binary cache:
|
|
|
|
```console
|
|
# nix log --store https://cache.nixos.org nixpkgs#hello
|
|
```
|

# Description
|
|
|
|
This command prints the log of a previous build of the derivation
|
|
*installable* on standard output.
|
|
|
|
Nix looks for build logs in two places:
|
|
|
|
* In the directory `/nix/var/log/nix/drvs`, which contains logs for
|
|
locally built derivations.
|
|
|
|
* In the binary caches listed in the `substituters` setting. Logs
|
|
should be named `<cache>/log/<base-name-of-store-path>`, where
|
|
`store-path` is a derivation,
|
|
e.g. `https://cache.nixos.org/log/dvmig8jgrdapvbyxb1rprckdmdqx08kv-hello-2.10.drv`.
|
|
For non-derivation store paths, Nix will first try to determine the
|
|
deriver by fetching the `.narinfo` file for this store path.
