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
hellopackage from https://cache.nixos.org to the local store:# nix store copy-log --from https://cache.nixos.org --eval-store auto nixpkgs#helloYou can verify that the log is available locally:
# nix log --substituters '' nixpkgs#hello(The flag
--substituters ''avoids queryinghttps://cache.nixos.orgfor 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-uri
URL of the source Nix store. -
--tostore-uri
URL of the destination Nix store.
Common evaluation options:
-
--argname expr
Pass the value expr as the argument name to Nix functions. -
--argstrname string
Pass the string string as the argument name to Nix functions. -
--eval-storestore-url
The Nix store to use for evaluations. -
--impure
Allow access to mutable paths and repositories. -
--include/-Ipath
Add path to the list of locations used to look up<...>file names. -
--override-flakeoriginal-ref resolved-ref
Override the flake registries, redirecting original-ref to resolved-ref.
Common flake-related options:
-
--commit-lock-file
Commit changes to the flake's lock file. -
--inputs-fromflake-url
Use the inputs of the specified flake as registry entries. -
--no-registries
Don't allow lookups in the flake registries. This option is deprecated; use--no-use-registries. -
--no-update-lock-file
Do not allow any updates to the flake's lock file. -
--no-write-lock-file
Do not write the flake's newly generated lock file. -
--override-inputinput-path flake-url
Override a specific flake input (e.g.dwarffs/nixpkgs). This implies--no-write-lock-file. -
--recreate-lock-file
Recreate the flake's lock file from scratch. -
--update-inputinput-path
Update a specific flake input (ignoring its previous entry in the lock file).
Options that change the interpretation of installables:
-
--derivation
Operate on the store derivation rather than its outputs. -
--exprexpr
Interpret installables as attribute paths relative to the Nix expression expr. -
--file/-ffile
Interpret installables as attribute paths relative to the Nix expression stored in file. If file is the character -, then a Nix expression will be read from standard input.
