bashtop

bashtop

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. Command-line argument parsing was never implemented, so it is launched simply as bashtop and configured from its in-app menu.bashtop is no longer actively developed. It was first rewritten in Python as bpytop, and then rewritten again in C++ as btop, which is the recommended replacement on all platforms.

~/.config/bashtop/bashtop.cfg

User configuration file. Controls theme, update interval, process sorting, and display options.

- CPU usage with core breakdown- Memory and swap usage- Disk I/O statistics- Network bandwidth- Process list with filtering- Mouse support- Customizable themes- Configuration menu

Display sections:- CPU - Usage graphs per core- Memory - RAM and swap usage- Disks - I/O and space usage- Network - Bandwidth by interface- Processes - Sortable process list

- q - Quit- m - Configuration menu- f - Filter processes- p/n - Sort processes- Arrow keys - Navigate- Mouse - Click to interact

Written in pure bash, with the performance limitations that implies. Requires bash 4.4 or newer. Relatively high CPU overhead for the monitoring itself. No longer maintained: superseded by bpytop (Python) and then btop (C++).

bashtop was created by aristocratos (Jakob Palme) in 2020 as a system monitor written entirely in bash, later rewritten as bpytop and then btop.
