Name
nix store copy-log - copy build logs between Nix stores
Synopsis
nix store copy-log [option…] installables…
Examples
|
• |
To copy the build log of the hello package 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
|
• |
--from store-uri |
URL of the source Nix store.
|
• |
Read installables from the standard input. No default installable applied.
|
• |
--to store-uri |
URL of the destination Nix store.
Common evaluation options
|
• |
--arg name expr |
Pass the value expr as the argument name to Nix functions.
|
• |
--arg-from-file name path |
Pass the contents of file path as the argument name to Nix functions.
|
• |
--arg-from-stdin name |
Pass the contents of stdin as the argument name to Nix functions.
|
• |
--argstr name string |
Pass the string string as the argument name to Nix functions.
|
• |
Start an interactive environment if evaluation fails.
|
• |
--eval-store store-url |
The URL of the Nix store to use for evaluation, i.e. to store derivations (.drv files) and inputs referenced by them.
|
• |
Allow access to mutable paths and repositories.
|
• |
--include / -I path |
Add path to search path entries used to resolve lookup paths
This option may be given multiple times.
Paths added through -I take precedence over the nix-path configuration setting and the NIX_PATH environment variable.
|
• |
--override-flake original-ref resolved-ref |
Override the flake registries, redirecting original-ref to resolved-ref.
Common flake-related options
|
• |
Commit changes to the flake’s lock file.
|
• |
--inputs-from flake-url |
Use the inputs of the specified flake as registry entries.
|
• |
Don’t allow lookups in the flake registries.
DEPRECATED
Use --no-use-registries instead.
|
• |
Do not allow any updates to the flake’s lock file.
|
• |
Do not write the flake’s newly generated lock file.
|
• |
--output-lock-file flake-lock-path |
Write the given lock file instead of flake.lock within the top-level flake.
|
• |
--override-input input-path flake-url |
Override a specific flake input (e.g. dwarffs/nixpkgs). This implies --no-write-lock-file.
|
• |
Recreate the flake’s lock file from scratch.
DEPRECATED
Use nix flake update instead.
|
• |
--reference-lock-file flake-lock-path |
Read the given lock file instead of flake.lock within the top-level flake.
|
• |
--update-input input-path |
Update a specific flake input (ignoring its previous entry in the lock file).
DEPRECATED
Use nix flake update instead.
Logging-related options
|
• |
Set the logging verbosity level to ‘debug’.
|
• |
--log-format format |
Set the format of log output; one of raw, internal-json, bar or bar-with-logs.
|
• |
--print-build-logs / -L |
Print full build logs on standard error.
|
• |
Decrease the logging verbosity level.
|
• |
--verbose / -v |
Increase the logging verbosity level.
Miscellaneous global options
|
• |
Show usage information.
|
• |
Disable substituters and consider all previously downloaded files up-to-date.
|
• |
--option name value |
Set the Nix configuration setting name to value (overriding nix.conf).
|
• |
Consider all previously downloaded files out-of-date.
|
• |
During evaluation, rewrite missing or corrupted files in the Nix store. During building, rebuild missing or corrupted store paths.
|
• |
Show version information.
Options that change the interpretation of installables
|
• |
--expr expr |
Interpret installables as attribute paths relative to the Nix expression expr.
|
• |
--file / -f file |
Interpret 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.conf for overriding configuration settings with command line flags.
