Get started with Midnight Commander, a visual shell and file manager for Linux
Midnight Commander (MC) is a text-based Command Line Interface (CLI) program. It is particularly useful when a GUI is not available but can also be used as a primary file manager in a terminal session even when you are using a GUI. Midnight Commander can be used to interact with local and remote Linux computers using the CLI.
The man page for Midnight Commander calls it a visual shell because it’s capabilities are greater than the file manager we usually use it as. This article will provide you with enough information to get started using Midnight Commander as a file manager as well as its other capabilities.

How to build rpm packages
Over the years I have created a number of Bash scripts, some of which have separate configuration files, that I like to install on most of my new computers and virtual machines.
