the contents of any of the given store paths have been modified.
E.g.
$ nix-store --verify-path $(nix-store -qR /var/run/current-system)
path `/nix/store/m2smyiwbxidlprfxfz4rjlvz2c3mg58y-etc' was modified! expected hash `fc87e271c5fdf179b47939b08ad13440493805584b35e3014109d04d8436e7b8', got `20f1a47281b3c0cbe299ce47ad5ca7340b20ab34246426915fce0ee9116483aa'
All paths are checked; the exit code is 1 if any path has been
modified, 0 otherwise.

Usage: nix-store [OPTIONS...] [ARGUMENTS...]
|
|
|
|
`nix-store' is a tool to manipulate the Nix store.
|
|
|
|
Operations:
|
|
|
|
--realise / -r: ensure path validity; if a derivation, ensure the
|
|
validity of the outputs
|
|
--add / -A: copy a path to the Nix store
|
|
--delete: safely delete paths from the Nix store
|
|
--query / -q: query information
|
|
--read-log / -l: print build log of given store paths
|
|
|
|
--register-validity: register path validity (dangerous!)
|
|
--check-validity: check path validity
|
|
|
|
--gc: run the garbage collector
|
|
|
|
--dump: dump a path as a Nix archive (NAR), forgetting dependencies
|
|
--restore: restore a path from a Nix archive, without
|
|
registering validity
|
|
|
|
--export: export a path as a Nix archive, marking dependencies
|
|
--import: import a path from a Nix archive, and register as
|
|
valid
|
|
|
|
--verify: verify Nix structures
|
|
--verify-path: verify whether the given store paths haven't been modified
|
|
--optimise: optimise the Nix store by hard-linking identical files
|
|
|
|
--query-failed-paths: list paths that failed to build (if enabled)
|
|
--clear-failed-paths: clear the failed status of the given paths
|
|
|
|
--version: output version information
|
|
--help: display help
|
|
|
|
Query flags:
|
|
|
|
--outputs: query the output paths of a Nix derivation (default)
|
|
--requisites / -R: print all paths necessary to realise the path
|
|
--references: print all paths referenced by the path
|
|
--referrers: print all paths directly refering to the path
|
|
--referrers-closure: print all paths (in)directly refering to the path
|
|
--tree: print a tree showing the dependency graph of the path
|
|
--graph: print a dot graph rooted at given path
|
|
--xml: emit an XML representation of the graph rooted at the given path
|
|
--hash: print the SHA-256 hash of the contents of the path
|
|
--size: print the size of the NAR dump of the path
|
|
--roots: print the garbage collector roots that point to the path
|
|
|
|
Query switches (not applicable to all queries):
|
|
|
|
--use-output: perform query on output of derivation, not derivation itself
|
|
--force-realise: realise the path before performing the query
|
|
--include-outputs: in `-R' on a derivation, include requisites of outputs
|
|
|
|
Garbage collector options:
|
|
|
|
--print-roots: print GC roots and exit
|
|
--print-live: print live paths and exit
|
|
--print-dead: print dead paths and exit
|
|
--delete: delete dead paths (default)
|
|
|
|
Options:
|
|
|
|
--verbose / -v: verbose operation (may be repeated)
|
|
--keep-failed / -K: keep temporary directories of failed builds
|
|
|
|
--add-root: add garbage collector roots for the result
