|
A top clone, written in Rust. Inspired by both [gtop](https://github.com/aksakalli/gtop) and [gotop](https://github.com/cjbassi/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](https://fonts2u.com/free-monospaced.font) and use a terminal like cmder for font support to work properly, unfortunately.
|
|
|
|
### macOS
|
|
|
|
macOS support will hopefully come soon<sup>TM</sup>.
|
|
|
|
## Usage
|
|
|
|
Note that all options and keybinds on GitHub may reflect the current development build, and not that of the current releases. For now, refer to the [crate](https://crates.io/crates/bottom) 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 2<sup>128 - 1</sup>. 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.
|
|
|
|
### Keybinds
|
|
|
|
#### 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 panel
|
|
|
|
- `dd` to kill the selected process - **I would highly recommend you to be careful using this, lest you accidentally kill the wrong 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.
|
|
|
|
### Mouse actions
|
|
|
|
[* Scrolling either scrolls through the list if the panel is a table (Temperature, Disks, Processes), or zooms in and out if it is a chart.]: <>
|
|
|
|
- Scrolling currently only scrolls through the list if the panel is a table (Temperature, Disks, Processes). This will change in the future.
