htop vs hw-probe

htop is a free, text-mode interactive process viewer for Linux and macOS. It runs in console or X terminals and requires ncurses, offering a command-line interface for watching and managing running processes. Current releases also list FreeBSD, NetBSD, OpenBSD, DragonFly BSD, and Solaris as supported systems. The project, founded in 2004, is distributed as source code on GitHub and as pre-compiled packages from operating-system distributors, with installation examples for Debian, Fedora, Gentoo, and Arch Linux; Homebrew includes it for macOS. Its display can show Unicode Braille graphs and a Unicode tree view, including visual support for large processor counts. Users can set I/O scheduling priority and CPU affinity, choose dark or light terminal themes, and customize header meters. The memory percentage covers process-used memory; htop does not provide a per-process SWAP column.

hw-probe is a free hardware probing tool for Linux and BSD systems, aimed at debugging computer problems and managing hardware inventory. It captures a snapshot of hardware state and logs, then provides a permanent URL to view the probe. If a device lacks a driver, it can suggest a Linux kernel version or third-party driver using LKDDb data. Users can create an inventory ID and mark probes to locate their computers on Linux-Hardware.org. Its monitoring command schedules a daily cron probe and emails alerts about operating-system failures, configuration changes, and hardware degradation. Optional tests check graphics, drive read speed, CPU performance, and RAM. Installation options include AppImage, Docker, Snap, Flatpak, Live CD/USB, and native packages. Uploads use HTTPS; selected logs can be disabled, and private details are decorated before upload, though edge-case failures are acknowledged. MAC addresses and serial numbers are represented by prefixes of salted SHA-512 hashes. The tool is dual-licensed under LGPL-2.1-or-later and BSD-4-Clause. The Snap package runs in a sandbox with limited functionality.
