nix profile list - list installed packages

nix profile list [option…]

•
Show what packages are installed in the default profile:
# nix profile list
Name:               gdb
Flake attribute:    legacyPackages.x86_64-linux.gdb
Original flake URL: flake:nixpkgs
Locked flake URL:   github:NixOS/nixpkgs/7b38b03d76ab71bdc8dc325e3f6338d984cc35ca
Store paths:        /nix/store/indzcw5wvlhx6vwk7k4iq29q15chvr3d-gdb-11.1
Name:               blender-bin
Flake attribute:    packages.x86_64-linux.default
Original flake URL: flake:blender-bin
Locked flake URL:   github:edolstra/nix-warez/91f2ffee657bf834e4475865ae336e2379282d34?dir=blender
Store paths:        /nix/store/i798sxl3j40wpdi1rgf391id1b5klw7g-blender-bin-3.1.2
Note that you can unambiguously rebuild a package from a profile through its locked flake URL and flake attribute, e.g.
# nix build github:edolstra/nix-warez/91f2ffee657bf834e4475865ae336e2379282d34?dir=blender#packages.x86_64-linux.default
will build the package blender-bin shown above.

This command shows what packages are currently installed in a profile. For each installed package, it shows the following information:

  • Name: A unique name used to unambiguously identify the package in invocations of nix profile remove and nix profile upgrade.
  • Index: An integer that can be used to unambiguously identify the package in invocations of nix profile remove and nix profile upgrade. (Deprecated, will be removed in a future version in favor of Name.)
  • Flake attribute: The flake output attribute path that provides the package (e.g. packages.x86_64-linux.hello).
  • Original flake URL: The original (“unlocked”) flake reference specified by the user when the package was first installed via nix profile install.
  • Locked flake URL: The locked flake reference to which the original flake reference was resolved.
  • Store paths: The store path(s) of the package.

•
--json
Produce output in JSON format, suitable for consumption by another program.
•
--profile path
The profile to operate on.

•
--arg name expr
Pass the value expr as the argument name to Nix functions.
•
--arg-from-file name path
Pass the contents of file path as the argument name to Nix functions.
•
--arg-from-stdin name
Pass the contents of stdin as the argument name to Nix functions.
•
--argstr name string
Pass the string string as the argument name to Nix functions.
•
--debugger
Start an interactive environment if evaluation fails.
•
--eval-store store-url
The URL of the Nix store to use for evaluation, i.e. to store derivations (.drv files) and inputs referenced by them.
•
--impure
Allow access to mutable paths and repositories.
•
--include / -I path
Add path to the Nix search path. The Nix search path is initialized from the colon-separated NIX_PATH environment variable, and is used to look up the location of Nix expressions using paths enclosed in angle brackets (i.e., <nixpkgs>).
For instance, passing
-I /home/eelco/Dev
-I /etc/nixos
will cause Nix to look for paths relative to /home/eelco/Dev and /etc/nixos, in that order. This is equivalent to setting the NIX_PATH environment variable to
/home/eelco/Dev:/etc/nixos
It is also possible to match paths against a prefix. For example, passing
-I nixpkgs=/home/eelco/Dev/nixpkgs-branch
-I /etc/nixos
will cause Nix to search for <nixpkgs/path> in /home/eelco/Dev/nixpkgs-branch/path and /etc/nixos/nixpkgs/path.
If a path in the Nix search path starts with http:// or https://, it is interpreted as the URL of a tarball that will be downloaded and unpacked to a temporary location. The tarball must consist of a single top-level directory. For example, passing
-I nixpkgs=https://github.com/NixOS/nixpkgs/archive/master.tar.gz
tells Nix to download and use the current contents of the master branch in the nixpkgs repository.
The URLs of the tarballs from the official nixos.org channels (see the manual page for nix-channel) can be abbreviated as channel:<channel-name>. For instance, the following two flags are equivalent:
-I nixpkgs=channel:nixos-21.05
-I nixpkgs=https://nixos.org/channels/nixos-21.05/nixexprs.tar.xz
You can also fetch source trees using flake URLs and add them to the search path. For instance,
-I nixpkgs=flake:nixpkgs
specifies that the prefix nixpkgs shall refer to the source tree downloaded from the nixpkgs entry in the flake registry. Similarly,
-I nixpkgs=flake:github:NixOS/nixpkgs/nixos-22.05
makes <nixpkgs> refer to a particular branch of the NixOS/nixpkgs repository on GitHub.
•
--override-flake original-ref resolved-ref
Override the flake registries, redirecting original-ref to resolved-ref.
•
--debug
Set the logging verbosity level to ‘debug’.
•
--log-format format
Set the format of log output; one of raw, internal-json, bar or bar-with-logs.
•
--print-build-logs / -L
Print full build logs on standard error.
•
--quiet
Decrease the logging verbosity level.
•
--verbose / -v
Increase the logging verbosity level.

•
--help
Show usage information.
•
--offline
Disable substituters and consider all previously downloaded files up-to-date.
•
--option name value
Set the Nix configuration setting name to value (overriding nix.conf).
•
--refresh
Consider all previously downloaded files out-of-date.
•
--repair
During evaluation, rewrite missing or corrupted files in the Nix store. During building, rebuild missing or corrupted store paths.
•
--version
Show version information.

Note

See man nix.conf for overriding configuration settings with command line flags.
