Unlike most terminal file-managers out there, CliFM replaces the traditional curses interface by a simple command-line interface. It is a file-manager, but also a shell extension.

This is already by far my favourite file manager.

imgp is a command line image resizer and rotator for JPEG and PNG images. It can resize (or thumbnail) and rotate thousands of images in a go, at lightning speed, while saving significantly on storage.

Jupyter notebooks are mostly known for their web-based user interface, such as JupyterLab or the Classic Notebook.

Rofi started as a clone of simpleswitcher, written by Sean Pringle - a popup window switcher roughly based on superswitcher. Simpleswitcher laid the foundations, and therefore Sean Pringle deserves most of the credit for this tool. Rofi (renamed, as it lost the simple property) has been extended with extra features, like an application launcher and ssh-launcher, and can act as a drop-in dmenu replacement, making it a very versatile tool.

Rofi, like dmenu, will provide the user with a textual list of options where one or more can be selected. This can either be running an application, selecting a window, or options provided by an external script.
