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
--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
