The sup command refers to a fast, console-based Mail User Agent (MUA) designed for efficient email management directly from your terminal. It distinguishes itself by indexing all your email, allowing for lightning-fast full-text searches, flexible tagging, and robust threading capabilities across large mail archives. sup supports various mail storage formats including IMAP, Maildir, and mbox. Written in Ruby, it provides a modern, keyboard-driven interface optimized for users who prefer working in a command-line environment and need powerful tools for organizing and navigating extensive email collections. Its primary goal is to provide a responsive and powerful email experience without leaving the console.

sup requires the Ruby programming language and specific RubyGems to function, which must be installed separately. Its configuration is managed through a Ruby file, ~/.sup/config.rb, which can be less intuitive for users unfamiliar with Ruby syntax. It is not pre-installed on most Linux distributions and usually requires manual installation.

sup's behavior is highly customizable through its configuration file, typically located at ~/.sup/config.rb. This file, written in Ruby, allows users to define mail accounts, configure keybindings, customize display options, set up indexing rules, and integrate with external commands for advanced mail processing.

The sup mail client emerged as a modern alternative for console-based email management, developed with a strong focus on speed and efficient handling of large email archives. Written in Ruby, it was designed to provide advanced features like comprehensive indexing and robust searching capabilities. Its development aimed to fill a niche for users seeking a powerful, keyboard-driven MUA beyond traditional console clients like Mutt, reflecting a trend towards more dynamic and scriptable command-line tools in the Linux ecosystem.
