to show only those derivations whose output is already in the Nix store or that can be substituted (i.e., downloaded from somewhere). In other words, it shows the packages that can be installed “quickly”, i.e., don’t need to be built from source.

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
|
|
|
|
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
|
|
|
|
--import / -I FILE: set default Nix expression
|
|
|
|

|
|
--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

|
|
default Nix expression as an argument
|
|

|
|
--attr / -A ATTRS...: select attributes by name from the default Nix
|
|

|
|
|

|

|
Query sources:
|
|
|
|
--installed: use installed derivations (default)
|
|
--available / -a: use derivations available in Nix expression
|
|
|
|
Query flags:
|
|
|
|
--status / -s: print installed/present status
|
|
--no-name: hide derivation names
|
|
--attr / -A: 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
|
|
--prebuilt-only: only show derivations whose prebuilt binaries are
|
|
available on this machine or are downloadable
|
|
|
|
Options:
|
|
|
|
--profile / -p LINK: use specified profile instead of target of ~/.nix-profile

|
|
