Useful TUI terminal apps on Linux

Linux Text User Interface (TUI) apps provide a powerful way to interact with your system directly through the terminal, combining ease of use with minimal resource consumption. Among the most popular and practical TUI apps for Linux are: 1. Lazyssh: This Go-based terminal SSH manager streamlines your SSH workflow by letting you browse, connect, tag, and edit SSH entries from your ~/.ssh/config file with simple keyboard shortcuts. It enhances remote server management efficiency for developers and system administrators. 2. Btop: A modern resource monitor written in C++, Btop offers an interactive and visually appealing real-time overview of CPU, memory, disk, and network usage. Its intuitive interface allows users to keep an eye on system performance with less effort than traditional command-line tools. 3. Midnight Commander (MC): A classic TUI file manager that allows you to navigate directories, manage files, and perform copy, move, or delete operations using either the keyboard or mouse. It’s designed for UNIX-like operating systems and is invaluable for users who prefer keyboard-driven workflows without launching a graphical file manager. 4. Zellij: A Rust-based terminal multiplexer designed for DevOps teams, offering features like floating and stacked panes, collaborative sessions, and WebAssembly-powered plugins. It facilitates multitasking and session management, making it easier to organize several terminal workspaces simultaneously. 5. K9s: This terminal UI tool simplifies Kubernetes management by providing live cluster insights and controls.
