A close to drop in replacement for cut that can use a regex delimiter instead of a fixed string. Additionally this tool allows for specification of the order of the output columns using the same column selection syntax as cut (see below for examples).

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.

rr aspires to be your primary C/C++ debugging tool for Linux, replacing — well, enhancing — gdb. You record a failure once, then debug the recording, deterministically, as many times as you want. The same execution is replayed every time.

rr also provides efficient reverse execution under gdb. Set breakpoints and data watchpoints and quickly reverse-execute to where they were hit.

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.
