systemctl list-unit-files [OPTIONS] [PATTERN...]

systemctl list-unit-files displays all installed unit files and their enablement states. Unlike `list-units` which shows runtime state, this shows the boot configuration for all available units.The output shows the unit file name and its state: enabled, disabled, static, masked, generated, transient, indirect, or alias.

Shows all installed unit files regardless of runtime state. Some unit files may be present but never used. Static units cannot be enabled directly.

The list-unit-files subcommand provides visibility into the full set of available units and their boot configuration, complementing `list-units` which shows only currently loaded units.
