copy build logs between Nix stores
Warning
This program is experimental and its interface is subject to change.
Synopsis
nix store copy-log [option…] installables…
Examples
- To copy the build log of the
hellopackage from https://cache.nixos.org to the local store:
# nix store copy-log --from https://cache.nixos.org --eval-store auto nixpkgs#hello
You can verify that the log is available locally:
# nix log --substituters '' nixpkgs#hello
(The flag --substituters '' avoids querying https://cache.nixos.org for the log.)
- To copy the log for a specific store derivation via SSH:
# nix store copy-log --to ssh-ng://machine /nix/store/ilgm50plpmcgjhcp33z6n4qbnpqfhxym-glibc-2.33-59.drv
Description
nix store copy-log copies build logs between two Nix stores. The source store is specified using --from and the destination using --to. If one of these is omitted, it defaults to the local store.
Options
--fromstore-uriURL of the source Nix store.
--stdinRead installables from the standard input. No default installable applied.
--tostore-uriURL of the destination Nix store.
Common evaluation options
--argname exprPass the value expr as the argument name to Nix functions.
--arg-from-filename pathPass the contents of file path as the argument name to Nix functions.
--arg-from-stdinnamePass the contents of stdin as the argument name to Nix functions.
--argstrname stringPass the string string as the argument name to Nix functions.
--debuggerStart an interactive environment if evaluation fails.
--eval-storestore-urlThe URL of the Nix store to use for evaluation, i.e. to store derivations (
.drvfiles) and inputs referenced by them.--impureAllow access to mutable paths and repositories.
--include/-IpathAdd path to search path entries used to resolve lookup paths
This option may be given multiple times.
Paths added through
-Itake precedence over thenix-pathconfiguration setting and theNIX_PATHenvironment variable .--override-flakeoriginal-ref resolved-refOverride the flake registries, redirecting original-ref to resolved-ref.
Miscellaneous global options
--helpShow usage information.
--offlineDisable substituters and consider all previously downloaded files up-to-date.
--optionname valueSet the Nix configuration setting name to value (overriding
nix.conf).--refreshConsider all previously downloaded files out-of-date.
--repairDuring evaluation, rewrite missing or corrupted files in the Nix store. During building, rebuild missing or corrupted store paths.
--versionShow version information.
Options that change the interpretation of installables
--exprexprInterpret installables as attribute paths relative to the Nix expression expr.
--file/-ffileInterpret installables as attribute paths relative to the Nix expression stored in file. If file is the character -, then a Nix expression is read from standard input. Implies
--impure.Note
See
man nix.conffor overriding configuration settings with command line flags.
