What it is
bottom is a free graphical process and system monitor that runs in the terminal on Linux, macOS, and Windows. It graphs CPU use by core and as an average, alongside RAM and swap use over time. Network and disk I/O are charted too, with controls for zooming the displayed time interval. Its process widget can display, sort, and search process information, send kill signals, and show a tree view. Other widgets cover disk capacity and use, temperature sensors, and battery use. Users can adjust themes, layout, widget behavior, and filtering through command-line options or a configuration file. The interface includes an htop-inspired basic mode and lets users expand a selected widget to fill the terminal. A read-only option prevents actions that affect the system, such as stopping processes. Installation is documented through package managers, Cargo, and pre-built release binaries. Official support covers Linux, macOS, and Windows, though architecture support varies by system. Android may work unofficially, with limited testing and support.
