# bottom
[](https://travis-ci.com/ClementTsang/bottom) [](https://crates.io/crates/bottom)
A cross-platform graphical process/system monitor. Inspired by both [gtop](https://github.com/aksakalli/gtop) and [gotop](https://github.com/cjbassi/gotop). Supports Linux, macOS, and Windows.
 _Terminal: Kitty Terminal, Font: IBM Plex Mono, OS: Arch Linux. Theme based on [gruvbox](https://github.com/morhetz/gruvbox) (see [sample config](./sample_configs/demo_config.toml))._
## Features
Features of bottom include:
- CPU widget to show a visual representation of per-core (and optionally average) usage.
- Memory widget to show a visual representation of both RAM and SWAP usage.
- Networks widget to show a log-based visual representation of network usage.
- Sortable and searchable process widget. Searching supports regex, and you can search by PID and process name.
- Disks widget to display usage and I/O per second.
- Temperature widget to monitor detected sensors in your system.
- Flags to customize the display.
- Config file support for custom colours and default options.
- Maximizing of widgets of interest to take up the entire window.
More details about each widget and compatibility can be found [here](./docs/widgets.md).
## Config files
For information about config files, see [this document](./docs/config.md) for more details, and this [config](./sample_configs/demo_config.toml) for an example.
## Installation
In all cases you can install the in-development version by cloning and using `cargo build --release`. Note this is built and tested with Rust Stable (1.41.0 as of writing). You can also get release versions using `cargo install bottom`, or manually building from the [Releases](https://github.com/ClementTsang/bottom/releases) page by downloading and building.
### Linux
Other installation methods based on distros are as follows:
#### Arch Linux
You can get the release versions from the AUR by installing `bottom`. For example:
```bash
yay bottom
```
#### Ubuntu
TBD
### Windows
I plan to add a Chocolatey install option in the future.
### macOS
You can get release versions using Homebrew:
```bash
brew tap clementtsang/bottom
brew install bottom
# Or
brew install clementtsang/bottom/bottom
```
## Usage
Run using `btm`.
### Command line options
- `-h`, `--help` shows the help screen and exits.
- `-a`, `--avg_cpu` 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.
- Temperature units (you can only use one at a time):
- `-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.
- `-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</sup> - 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.
- `-g`, `--group` will group together processes with the same name by default (equivalent to pressing `Tab`).
- `-S`, `--case_sensitive` will default to matching case.
- `-W`, `--whole` will default to searching for the world word.
- `-R`, `--regex` will default to using regex.
- `--cpu_default`, `--memory_default`, `--disk_default`, `--temperature_default`, `--network_default`, `--process_default` will select the corresponding widget on startup. By default the process widget is selected.
- `-s`, `--show_disabled_data` will show data entries in the graph legends even if the lines for that entry are disabled.
- `-C`, `--config` takes in a file path leading to a TOML file.
### Keybindings
#### General
- `q`, `Ctrl-c` to quit. Note if you are currently in the search widget, `q` will not work so you can still type.
- `Esc` to close a dialog window, widget, or exit maximized mode.
- `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/Shift`-arrow or `H/J/K/L` to navigate between widgets. **Note that on macOS, some keybindings may collide with existing ones; `H/J/K/L` should work however.**
- `Up` or `k` and `Down` or `j` scrolls through the list if the widget is a table (Temperature, Disks, Processes).
- `?` to get a help screen explaining the controls. Note all controls except `Esc` to close the dialog will be disabled while this is open.
- `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.
- `Enter` on a widget to maximize the widget.
#### CPU
- `/` to allow for enabling/disabling showing certain cores with `Space`.
#### 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.
- `Ctrl-f` or `/` to open the search widget.
#### Search widget
- `Tab` to switch between searching for PID and name respectively.
- `Esc` to close.
- `Ctrl-a` and `Ctrl-e` to jump to the start and end of the search bar respectively.
- `Ctrl-u` to clear the current search query.
- `Backspace` to delete one character behind the current cursor position.
- `Delete` to delete one character at the current cursor position.
- `Left` and `Right` arrow keys to move the cursor within the search bar.
- `Alt-c` to toggle ignoring case.
- `Alt-m` to toggle matching the entire word.
- `Alt-r` to toggle using regex.
Note that `q` is disabled while in the search widget.
### Mouse actions
- Scrolling with the mouse will scroll through the currently selected list if the widget is a scrollable table.
