bottom (btm) vs btop

bottom is a free graphical system and process monitor that runs in a terminal on Linux, macOS and Windows. It charts CPU use for each core and as an average, along with RAM and swap over time. Network and disk I/O are graphed too, with a control for zooming the displayed time interval. Its process widget lets users display, sort and search process information, use tree mode and send kill signals. Other widgets show disk capacity and use, temperature sensors and battery use. Appearance and behavior can be changed through command-line options or a configuration file, including themes, layout, widget behavior and filtering. An htop-inspired basic mode offers a simpler view, and a selected widget can be expanded to fill the terminal. A read-only option blocks actions that affect the system, such as stopping processes. Installation is documented through package managers, Cargo and pre-built release binaries. Official platform support covers macOS, Linux and Windows; architecture support varies by system. Android and some other systems may work unofficially with limited testing and support.

btop is a free resource monitor for Linux and macOS that displays processor, memory, disk, network, and process activity. Its game-inspired menus, mouse support, and responsive interface provide ways to navigate system views and process controls. Users can inspect process details, filter or sort the list, view it as a tree, send signals, or pause the process list. Network graphs scale automatically; other displays cover disk activity and speeds, plus a battery meter. Users can choose graph symbols, create presets, and use theme files shared with bpytop and bashtop or a custom themes directory. GPU monitoring is supported on Linux and on macOS with Apple Silicon GPUs when built with GPU support. NVIDIA monitoring needs the nvidia-ml library, AMD needs rocm_smi_lib, and Intel needs SYSFS read permission. The project documents Linux and macOS installation, package installation for FreeBSD and NetBSD, and Homebrew for macOS and Linux. It recommends a terminal with 24-bit truecolor and wide-character support, a UTF8 locale, and a font covering specified Unicode blocks. The repository lists the Apache-2.0 license.
