kupfer - Convenient command and access tool for applications and documents


kupfer [ OPTIONS | FILE ... ]
kupfer-exec FILE ...


Kupfer is an interface for quick and convenient access to applications and their documents.

The most typical use is to find a specific application and launch it. We have tried to make Kupfer easy to extend with plugins so that this quick-access paradigm can be extended to many more objects than just applications.

kupfer-exec is a helper script that can execute commands saved to file, but only by connecting to an already running instance of Kupfer.


Running kupfer on the command line (without options) will try to show the program it if already running.

Kupfer can be invoked with a list of files

kupfer FILE ...

The file paths will be sent to and selected in an already running instance of the program.

You may also pipe text to kupfer to pass it to a currently running instance.

Custom plugins are added to kupfer by installing them to the directory ~/.local/share/kupfer/plugins, or any kupfer/plugins directory in any of $XDG_DATA_DIRS.


If KUPFER_NO_CUSTOM_PLUGINS is set, only allow loading built-in plugins (installed in the program's python package).

If KUPFER_NO_CACHE is set, do not load from or write to any source cache files.

If KUPFER_NO_KEYBINDER is set do not use Keybinder even if it is installed.
