![ci](https://github.com/ClementTsang/bottom/workflows/ci/badge.svg)
[![crates.io link](https://img.shields.io/crates/v/bottom.svg)](https://crates.io/crates/bottom)
A cross-platform graphical process/system monitor with a customizable interface and a multitude of features. Supports Linux, macOS, and Windows. Inspired by both [gtop](https://github.com/aksakalli/gtop) and [gotop](https://github.com/cjbassi/gotop).
![Quick demo recording showing off searching, expanding, and process killing.](assets/demo.gif) _Theme based on [gruvbox](https://github.com/morhetz/gruvbox)_ (`--color gruvbox`). _Font is [IBM Plex Mono](https://www.ibm.com/plex/), terminal is [Kitty](https://sw.kovidgoyal.net/kitty/)._
**Note**: If you are reading this on the master branch, then it may refer to in-development or un-released features/changes. Please refer to [release branch](https://github.com/ClementTsang/bottom/tree/release/README.md) or [crates.io](https://crates.io/crates/bottom) for the most up-to-date _release_ documentation.

## Installation
Note that bottom is:
- Built on the stable version of Rust
- Officially tested and released for only `x86_64` (and `i686` for Windows)
- Developed mainly for macOS, Windows, and Linux
Anything outside of this (i.e: ARM builds, building on Nightly, building on another OS) is currently not guaranteed, even if it does happen to work. For example, ARM is compiled on the CI pipeline and release builds will be provided, but not all features may work (such as R/s and W/s for disks).
### Manually
There are a few ways to go about doing this manually. If you do so, please build using the current stable release of Rust. For example:
```bash
# If required, update Rust on the stable channel
rustup update stable
# Clone and install the newest master version all via Cargo
cargo install --git https://github.com/ClementTsang/bottom
# Clone from master and install manually
git clone https://github.com/ClementTsang/bottom
cd bottom
cargo install --path .
# Download from releases and install
curl -LO https://github.com/ClementTsang/bottom/archive/0.5.4.tar.gz
tar -xzvf 0.5.4.tar.gz
cargo install --path .
```
Or, you can just download the binary from the [latest release](https://github.com/ClementTsang/bottom/releases/latest).
### Cargo
```bash
# If required, update Rust on the stable channel
rustup update stable
cargo install bottom
# OR, --locked may be required due to how cargo install works
cargo install bottom --locked
```
### AUR
```bash
yay -S bottom
# If you instead want a pre-built binary:
yay -S bottom-bin
```
### Debian
A `.deb` file is provided on each [release](https://github.com/ClementTsang/bottom/releases/latest):
```bash
curl -LO https://github.com/ClementTsang/bottom/releases/download/0.5.4/bottom_0.5.4_amd64.deb
sudo dpkg -i bottom_0.5.4_amd64.deb
```
### Fedora/CentOS
Available in [COPR](https://copr.fedorainfracloud.org/coprs/atim/bottom/):
```bash
sudo dnf copr enable atim/bottom -y
sudo dnf install bottom
```
### Gentoo
Available in [dm9pZCAq overlay](https://github.com/gentoo-mirror/dm9pZCAq)
```bash
sudo eselect repository enable dm9pZCAq
sudo emerge --sync dm9pZCAq
sudo emerge sys-process/bottom::dm9pZCAq
```
### Nix
```bash
nix-env -i bottom
```
### Homebrew
```bash
brew tap clementtsang/bottom
brew install bottom
# If you need to be more specific, use:
brew install clementtsang/bottom/bottom
```
### Scoop
```bash
scoop install bottom
```
### Chocolatey
Choco package located [here](https://chocolatey.org/packages/bottom). Since you cannot upload a
new package while a previous one is being validated, the newest version of a release may take a while
to appear.
```bash
choco install bottom
# Version number may be required for newer releases, if available:
choco install bottom --version=0.5.4
```
### winget
You can find the packages [here](https://github.com/microsoft/winget-pkgs/tree/master/manifests/Clement/bottom).
Since validation of the package takes time, it may take a while to become available after a release.
```bash
winget install bottom
```
You can also manually do the same thing by going to the [latest release](https://github.com/ClementTsang/bottom/releases/latest)
and installing via the `.msi` file.
You can uninstall via Control Panel or Options in Windows.
### Auto-completion
Shell completions are included in binary releases, and are generated in the same directory as the
binary if bottom is manually built.
- For bash, move `btm.bash` to `$XDG_CONFIG_HOME/bash_completion or /etc/bash_completion.d/`.
- For fish, move `btm.fish` to `$HOME/.config/fish/completions/`.
- For zsh, move `_btm` to one of your `$fpath` directories.
- For PowerShell, add `. _btm.ps1` to your PowerShell
[profile](<https://docs.microsoft.com/en-us/previous-versions//bb613488(v=vs.85)>).
Some install scripts (i.e. AUR) will automatically do this for you.

## Features
As yet _another_ process/system visualization and management application, bottom supports the typical features:
- CPU usage visualization, on an average and per-core basis
- RAM and swap usage visualization
- Network visualization for receiving and transmitting, on a log-graph scale
- Display information about disk capacity and I/O per second
- Display temperatures from sensors
- Display information regarding processes, like CPU, memory, I/O usage, and process state
- Process management (well, if process killing is all you need)
It also aims to be:
- Lightweight
- Cross-platform - supports 64-bit Linux, Windows, and macOS
In addition, bottom also currently has the following features:
### Processes
#### Process searching
On any process widget, hit `/` to bring up a search bar. If the layout has multiple process widgets, note this search is independent of other widgets.
![search bar image](assets/search_empty.png)
By default, just typing in something will search by process name:
![a simple search](assets/simple_search.png)
This simple search can be refined by matching by case, matching the entire word, or by using regex:
![a slightly better search](assets/regex_search.png)
Now let's say you want to search for two things - luckily, we have the `AND` and `OR` logical operators:
![logical operator demo with just ors](assets/or_search.png)
![logical operator demo with ands and ors](assets/and_or_search.png)
Furthermore, one is able to refine their searches by CPU usage, memory usage, PID, and more. For example:
![using cpu filter](assets/usage_search.png)
You can see all available keywords and query options [here](#process-searching-keywords).
#### Process sorting
You can sort the processes list by any column you want by pressing `s` while on a process widget:
![sorting](assets/sort.png)
#### Tree mode
Use `t` or `F5` to toggle tree mode in a process widget. This is somewhat similar to htop's tree
mode.
![Standard tree](assets/trees_1.png)
Sorting works as well, but it is done per groups of siblings. For example, by CPU%:
![Standard tree](assets/trees_2.png)
You can also still filter processes. Branches that entirely do not match the query are pruned out,
but if a branch contains an element that does match the query, any non-matching elements will instead
just be greyed out, so the tree structure is still maintained:
![Standard tree](assets/trees_3.png)
### Zoom
Using the `+`/`-` keys or the scroll wheel will move the current time intervals of the currently selected widget, and `=` to reset the zoom levels to the default.
Widgets can hold different time intervals independently. These time intervals can be adjusted using the
`-t`/`--default_time_value` and `-d`/`--time_delta` options, or their corresponding config options.
### Expand
Only care about one specific widget? You can go to that widget and hit `e` to make that widget expand and take
up the entire drawing area. You can minimize this expanded widget with `Esc` or pressing `e` again.
### Basic mode
Using the `-b` or `--basic_mode` (or their corresponding config options) will open bottom in basic mode.
There are no charts or expanded mode when using this, and tables are condensed such that only one table is displayed
at a time.
![basic mode image](assets/basic_mode.png)
Note custom layouts are currently not available when this is used.
### Config files
bottom supports reading from a config file to customize its behaviour and look.
By default, bottom will look at (based on [dirs](https://github.com/dirs-dev/dirs-rs#features)):
| OS | Location |
| ----------------------------------------------------------------------- | -------- |
| `~/.config/bottom/bottom.toml` or `$XDG_CONFIG_HOME/bottom/bottom.toml` | Linux |
| `$HOME/Library/Application Support/bottom/bottom.toml` | macOS |
| `C:\Users\<USER>\AppData\Roaming\bottom\bottom.toml` | Windows |
Note that if a config file does not exist at either the default location or the passed in location via `-C` or `--config`, one is automatically created with no settings applied.
#### Config flags
The following options can be set under `[flags]` to achieve the same effect as passing in a flag on runtime. Note that if a flag is given, it will override the config file.
These are the following supported flag config values, which correspond to the flag of the same name described in [Flags](#flags):
| Field | Type |
| ------------------------ | ------------------------------------------------------------------------------------- |
| `hide_avg_cpu` | Boolean |
| `dot_marker` | Boolean |
| `left_legend` | Boolean |
| `current_usage` | Boolean |
| `group_processes` | Boolean |
| `case_sensitive` | Boolean |
| `whole_word` | Boolean |
| `regex` | Boolean |
| `show_disabled_data` | Boolean |
| `basic` | Boolean |
| `hide_table_count` | Boolean |
| `use_old_network_legend` | Boolean |
| `battery` | Boolean |
| `rate` | Unsigned Int (represents milliseconds) |
| `default_time_value` | Unsigned Int (represents milliseconds) |
| `time_delta` | Unsigned Int (represents milliseconds) |
| `temperature_type` | String (one of ["k", "f", "c", "kelvin", "fahrenheit", "celsius"]) |
| `default_widget_type` | String (one of ["cpu", "proc", "net", "temp", "mem", "disk"], same as layout options) |
| `default_widget_count` | Unsigned Int (represents which `default_widget_type`) |
| `disable_click` | Boolean |
| `color` | String (one of ["default", "default-light", "gruvbox", "gruvbox-light"]) |
| `mem_as_value` | Boolean |
| `tree` | Boolean |
#### Theming
The config file can be used to set custom colours for parts of the application under the `[colors]` object. The following labels are customizable with strings that are hex colours, RGB colours, or specific named colours.
Supported named colours are one of the following strings: `Reset, Black, Red, Green, Yellow, Blue, Magenta, Cyan, Gray, DarkGray, LightRed, LightGreen, LightYellow, LightBlue, LightMagenta, LightCyan, White`.
| Labels | Details | Example |
| ------------------------------- | ------------------------------------------------------- | ------------------------------------------------------- |
| Table header colours | Colour of table headers | `table_header_color="255, 255, 255"` |
| CPU colour per core | Colour of each core. Read in order. | `cpu_core_colors=["#ffffff", "white", "255, 255, 255"]` |
| Average CPU colour | The average CPU color | `avg_cpu_color="White"` |
| All CPUs colour | The colour for the "All" CPU label | `all_cpu_color="White"` |
| RAM | The colour RAM will use | `ram_color="#ffffff"` |
| SWAP | The colour SWAP will use | `swap_color="#ffffff"` |
| RX | The colour rx will use | `rx_color="#ffffff"` |
| TX | The colour tx will use | `tx_color="#ffffff"` |
| Widget title colour | The colour of the label each widget has | `widget_title_color="#ffffff"` |
| Border colour | The colour of the border of unselected widgets | `border_color="#ffffff"` |
| Selected border colour | The colour of the border of selected widgets | `highlighted_border_color="#ffffff"` |
| Text colour | The colour of most text | `text_color="#ffffff"` |
| Graph colour | The colour of the lines and text of the graph | `graph_color="#ffffff"` |
| Cursor colour | The cursor's colour | `cursor_color="#ffffff"` |
| Selected text colour | The colour of text that is selected | `scroll_entry_text_color="#ffffff"` |
| Selected text background colour | The background colour of text that is selected | `scroll_entry_bg_color="#ffffff"` |
| High battery level colour | The colour used for a high battery level (100% to 50%) | `high_battery_color="green"` |
| Medium battery level colour | The colour used for a medium battery level (50% to 10%) | `medium_battery_color="yellow"` |
| Low battery level colour | The colour used for a low battery level (10% to 0%) | `low_battery_color="red"` |
#### Layout
bottom supports customizable layouts via the config file. Currently, layouts are controlled by using TOML objects and arrays.
For example, given the sample layout:
```toml
[[row]]
[[row.child]]
type="cpu"
[[row]]
ratio=2
[[row.child]]
ratio=4
type="mem"
[[row.child]]
ratio=3
[[row.child.child]]
type="temp"
[[row.child.child]]
type="disk"
```
This would give a layout that has two rows, with a 1:2 ratio. The first row has only the CPU widget.
The second row is split into two columns with a 4:3 ratio. The first column contains the memory widget.
The second column is split into two rows with a 1:1 ratio. The first is the temperature widget, the second is the disk widget.
This is what the layout would look like when run:
![Sample layout](assets/sample_layout.png)
Each `[[row]]` represents a _row_ in the layout. A row can have any number of `child` values. Each `[[row.child]]`
represents either a _column or a widget_. A column can have any number of `child` values as well. Each `[[row.child.child]]`
represents a _widget_. A widget is represented by having a `type` field set to a string.
The following `type` values are supported:
| | |
| -------------------------------- | ------------------------ |
| `"cpu"` | CPU chart and legend |
| `"mem", "memory"` | Memory chart |
| `"net", "network"` | Network chart and legend |
| `"proc", "process", "processes"` | Process table and search |
| `"temp", "temperature"` | Temperature table |
| `"disk"` | Disk table |
| `"empty"` | An empty space |
| `"batt", "battery"` | Battery statistics |
Each component of the layout accepts a `ratio` value. If this is not set, it defaults to 1.
For an example, look at the [default config](./sample_configs/default_config.toml), which contains the default layout.
Furthermore, you can have duplicate widgets. This means you could do something like:
```toml
[[row]]
ratio=1
[[row.child]]
type="cpu"
[[row.child]]
type="cpu"
[[row.child]]
type="cpu"
[[row]]
ratio=1
[[row.child]]
type="cpu"
[[row.child]]
type="empty"
[[row.child]]
type="cpu"
[[row]]
ratio=1
[[row.child]]
type="cpu"
[[row.child]]
type="cpu"
[[row.child]]
type="cpu"
```
and get the following CPU donut:
![CPU donut](./assets/cpu_layout.png)
#### Disk and temperature filtering
You can hide specific disks and temperature sensors by name in the config file via `disk_filter` and `temp_filter` respectively. Regex (`regex = true`) and case-sensitivity (`case_sensitive = true`) are supported, but are off by default.
For example, let's say , given this disk list:
![Disk filter not ignoring list](./assets/disk_filter_pre.png)
I wish to _only_ show disks that follow the form `/dev/sda\d+`, or `/dev/nvme0n1p2`:
```toml
[disk_filter]
is_list_ignored = false
list = ["/dev/sda\\d+", "/dev/nvme0n1p2"]
regex = true
```
![Disk filter not ignoring list](./assets/disk_filter_post.png)
This would ignore anything that does not match either of these two conditions. If I instead wish to ignore anything that matches this list, then I can set `is_list_ignored = true` instead:
![Disk filter ignoring list](./assets/disk_filter_post2.png)
Likewise, I can do something similar for `temp_filter`:
![Temp filter before](./assets/temp_filter_pre.png)
If I, say, only wanted to see any entry with the words "cpu" or "wifi" in it, case sensitive:
```toml
[temp_filter]
is_list_ignored = false
list = ["cpu", "wifi"]
case_sensitive = true
```
![Temp filter after](./assets/temp_filter_post.png)
Now, flipping to `case_sensitive = false` would instead show:
![Temp filter after with case sensitivity off](./assets/temp_filter_post2.png)
### Battery
You can get battery statistics (charge, time to fill/discharge, consumption in watts, and battery health) via the battery widget.
Since this is only useful for devices like laptops, it is off by default. You can either enable the widget in the default layout via the `--battery` flag, or by specifying the widget in a [layout](#layout):
![Battery example](assets/battery.png)
### Compatibility
The current compatibility of widgets with operating systems from personal testing:

## Thanks
- This project is very much inspired by both
[gotop](https://github.com/cjbassi/gotop), its successor
[ytop](https://github.com/cjbassi/ytop), and [gtop](https://github.com/aksakalli/gtop).
- Basic mode is heavily inspired by [htop's](https://hisham.hm/htop/) design.
- This application was written with many, _many_ libraries, and built on the
work of many talented people. This application would be impossible without their
work. I used to thank them all individually but the list got too large...
- And of course, thanks to all contributors!
