When ‘--help’ is given, just run ‘man’ to show the manual page

Usage: nix-env [OPTIONS...] [ARGUMENTS...]
|
||||
|
||||
`nix-env' is a tool to manipulate Nix user environments.

Operations:
|
||||
|
||||
--install / -i: add derivations to the user environment

||||
--upgrade / -u: upgrade derivation in the user environment
|
||||
--set: create a user environment containing a single derivation
|
||||
--uninstall / -e: remove derivations from the user environment
|
||||
--query / -q: perform a query on an environment or Nix expression
|
||||
--set-flag NAME VALUE: set derivation meta-attribute to given value
|
||||
|
||||
The previous operations take a list of derivation names. The special
|
||||
name `*' may be used to indicate all derivations.
|
||||
|
||||
--switch-profile / -S [FILE]: switch to specified profile
|
||||
--switch-generation / -G NUMBER: switch to specified generation of profile
|
||||
--rollback: switch to the previous generation
|
||||
--list-generations: list available generations of a profile
|
||||
--delete-generations GENERATIONS...: deleted listed generations,
|
||||
`old' for all non-current generations
|
||||
|
||||
--version: output version information
|
||||
--help: display help
|
||||
|
||||
Install / upgrade / uninstall flags:
|

--dry-run: show what would be done, but don't do it
|
||||
|
||||
Installation sources:
|
||||
|
||||
--from-expression / -E EXPR...: evaluate expressions specified on
|
||||
the command line; expressions should be functions that take the
|
||||
default Nix expression as an argument
|
||||
--from-profile PROFILE NAMES...: copy named packages from PROFILE
|
||||
--attr / -A ATTRS...: select attributes by name from the default Nix
|
||||
expression
|
||||
|
||||
Upgrade flags:
|
||||
|
||||
--lt: upgrade if the current version is older (default)
|
||||
--leq: upgrade if the current version is older or equal
|
||||
--eq: "upgrade" if the current version is equal
|
||||
--always: upgrade regardless of current version
|
||||
|
||||
Query sources:
|
||||
|
||||
--installed: use installed derivations (default)
|
||||
--available / -a: use derivations available in Nix expression
|
||||
|
||||
Query flags:
|
||||
|
||||
--xml: show output in XML format
|
||||
--status / -s: print installed/present status
|
||||
--no-name: hide derivation names
|
||||
--attr-path / -P: shows the unambiguous attribute name of the
|
||||
derivation which can be used when installing with -A
|
||||
--system: print the platform type of the derivation
|
||||
--compare-versions / -c: compare version to available or installed
|
||||
--drv-path: print path of derivation
|
||||
--out-path: print path of derivation output
|
||||
--description: print description
|
||||
--meta: print all meta attributes (only with --xml)
|
||||
|
||||
Options:
|
||||
|
||||
--profile / -p LINK: use specified profile instead of target of ~/.nix-profile
|
||||
--file / -f FILE: use Nix expression FILE for installation, etc.
|
||||
--verbose / -v: verbose operation (may be repeated)
|
||||
--keep-failed / -K: keep temporary directories of failed builds
|
||||
--keep-going / -k: build as many dependencies as possible, even if
|
||||
some dependencies fail to build
|
||||
--preserve-installed: do not replace currently installed versions in `-i'
|
||||
--system-filter SYSTEM: only use derivations for specified platform
|
||||
--prebuilt-only / -b: only use derivations whose prebuilt binaries are

||||
available on this machine or are downloadable

Usage: nix-instantiate [OPTIONS...] [FILES...]
|
||||
|
||||

|
||||
standard input.

|
||||
--version: output version information

|
||||
|
||||

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
|
||||
--keep-going / -k: build as many dependencies as possible, even if
|
||||
some dependencies fail to build
|
||||
|
||||
--add-root: add garbage collector roots for the result

Usage: nix-worker [OPTIONS...] [--daemon | --slave]
|
||||
|
||||
`nix-worker' is a helper program used to implement secure, multi-user
|
||||
Nix stores. In `--daemon' mode, it goes into the background and waits
|
||||
for incoming connections on a Unix domain socket, and forks a process
|
||||
for each connection to perform the Nix store operations requested by
|
||||
the caller. In `--slave' mode, `nix-worker' is called directly, and
|
||||
the caller and the worker communicate with each other over
|
||||
stdin/stdout. In this mode, the `nix-worker' program should have
|
||||
appropriate setuid privileges.
