SYNOPSIS¶

DESCRIPTION¶

Install package(s) to environment.

OPTIONS¶

General Options¶

Many flox commands wrap Nix commands of the same name, and will correspondingly pass on options and arguments directly to the underlying nix invocation. For more information on the options supported by specific Nix commands please invoke flox nix <command> help.

The following options are used specifically by flox and must be specified before the <command> argument.

-v, --verbose
Verbose mode. Invoke multiple times for increasing detail.

--debug
Debug mode. Invoke multiple times for increasing detail.

-V, --version
Print flox version.

--prefix
Print flox installation prefix / Nix store path. (flox internal use only.)

--bash-passthru
Force execution in flox-bash (flox internal use only.)

Environment Options¶

The following option is supported by environment commands:

(-e|–environment) <name>
Selects flox environment to be modified or used. If not provided then flox will fall back to using the default environment.

Package Options¶

Flox package arguments are specified as a tuple of stability, channel, name, and version in the format: <stability>.<channel>.<name>@<version>

The version field is optional, defaulting to the latest version if not specified.

The stability field is also optional, defaulting to “stable” if not specified.

The channel field is also optional, defaulting to “nixpkgs-flox” if not specified, but only if using the “stable” stability. If using anything other than the default “stable” stability, the channel must be specified.

For example, each of the following will install the latest hello version 2.12 from the stable channel:

flox install [email protected]
flox install stable.nixpkgs-flox.hello
flox install [email protected]
flox install nixpkgs-flox.hello
flox install [email protected]
flox install hello

… and each of the following will install the older hello version 2.10 from the stable channel:

flox install [email protected]
flox install [email protected]
flox install [email protected]

… but only the following will install the older hello version 2.10 from the unstable channel:

flox install [email protected]
