bottom

A graphical top clone, written in Rust. Inspired by both gtop and gotop

Installation

Linux

You can install by cloning and using cargo build --release, or use cargo install bottom.

Windows

You can currently install by cloning and building yourself using cargo build --release, or use cargo install bottom . You may need to install a font like FreeMono and use a terminal like cmder for font support to work properly, unfortunately.

macOS

macOS support will hopefully come soon^TM.

Support

The compatibility of each widget and operating systems are, as of version 0.1.0, as follows:

OS/Widget	CPU	Memory	Disks	Temperature	Processes	Networks
Linux	✓	✓	✓	✓	✓	✓
Windows	✓	✓	✓	Currently not working	✓	Partially supported (total RX/TX unavailable)
macOS	Untested	Untested	Untested	Untested	Untested	Untested

Usage

Command line options

• -h, --help shows the help screen and exits.

• -a, --avgcpu enables also showing the average CPU usage in addition to per-core CPU usage.

• -m, --dot-marker uses a dot marker instead of the default braille marker.

• -c, --celsius displays the temperature type in Celsius. This is the default.

• -f, --fahrenheit displays the temperature type in Fahrenheit.

• -k, --kelvin displays the temperature type in Kelvin.

• -v, --version displays the version number and exits.

• -d, --debug enables debug logging.

• -r <RATE>, --rate <RATE> will set the refresh rate in milliseconds. Lowest it can go is 250ms, the highest it can go is 2¹²⁸ - 1. Defaults to 1000ms, and lower values may take more resources due to more frequent polling of data, and may be less accurate in some circumstances.

• -l, --left_legend will move external table legends to the left side rather than the right side. Right side is default.

• -u, --current_usage will make a process' CPU usage be based on the current total CPU usage, rather than assuming 100% CPU usage. Only affects Linux for now.

• g, --group will group together processes with the same name by default (equivalent to pressing Tab).

Keybindings

General

• q, Ctrl-c to quit.

• Ctrl-r to reset the screen and reset all collected data.

• f to freeze the screen from updating with new data. Press f again to unfreeze. Note that monitoring will still continue in the background.

• Ctrl+Up/k, Ctrl+Down/j, Ctrl+Left/h, Ctrl+Right/l to navigate between panels.

• Esc to close a dialog window.

• ? to get a help screen explaining the controls. Note all controls except Esc to close the dialog will be disabled while this is open.

Scrollable Tables

• Up and Down scrolls through the list if the panel is a table (Temperature, Disks, Processes).

• gg or Home to jump to the first entry of the current table.

• G (Shift+g) or End to jump to the last entry of the current table.

Processes

• dd to kill the selected process

• c to sort by CPU usage. Sorts in descending order by default. Press again to reverse sorting order.

• m to sort by memory usage. Sorts in descending order by default. Press again to reverse sorting order.

• p to sort by PID. Sorts in ascending order by default. Press again to reverse sorting order.

• n to sort by process name. Sorts in ascending order by default. Press again to reverse sorting order.

• Tab to group together processes with the same name. Disables PID sorting. dd will now kill all processes covered by that name.

Mouse actions

• Scrolling with the mouse will scroll through the currently selected list, similar to using the up/down arrow keys.
