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

Installation

Linux

You can install by cloning and using cargo build --release, or download the pre-compiled binary in Releases.

Windows

You can currently install by cloning and building yourself using cargo build --release. 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.

Usage

Note that all options and keybindings on GitHub may reflect the current development build, and not that of the current releases. For now, refer to the crate README for documentation as of time of release.

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.

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.

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

• 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.

Processes, temperature, and disk panels

• 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.

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

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

Mouse actions

• Scrolling currently only scrolls through the list if the panel is a table (Temperature, Disks, Processes).
