bashtop [options]

bashtop is a resource monitor written in bash showing CPU, memory, disk, network, and process information in a terminal UI. It provides an attractive, mouse-enabled interface for system monitoring.
The tool offers game-like visuals and interactivity while remaining a pure bash script.

Written in pure bash (performance limitations). Superseded by bpytop (Python) and btop++ (C++). Requires bash 4.4+. High CPU usage for monitoring itself. No longer actively maintained.

bashtop was created by Jakob Palme (aristocratos) in 2020 as a proof-of-concept system monitor in pure bash, later rewritten as bpytop and btop++.
