nix-env: Upgrade one package.
$ nix-env -u ${pkg_name}
try on your machine

This command is used in the Nix package manager to upgrade or update a specific package. Here is a breakdown of the command:

  • nix-env is the main command used to manage packages in Nix.
  • -u is a flag that stands for "upgrade." It tells nix-env to upgrade the specified package to its latest available version.
  • ${pkg_name} is a placeholder for the name of the package you want to upgrade. You need to replace ${pkg_name} with the actual name of the package you want to upgrade.

For example, if you want to upgrade the package named "example-package", the command would be: nix-env -u example-package.

By running this command, nix-env will check for a newer version of the specified package and upgrade it if available.
