Support

Note that bottom is:

Built and released using the most recent stable version of Rust
Officially supports:
- macOS (x86_64)
- Linux (x86_64, i686, aarch64)
- Windows (x86_64, i686)

Operating systems, versions of Rust, or platforms that are outside of this list are not currently officially supported - even if it is built, tested, or works - and I may not be able to fix bugs for these!

Compatibility

The current compatibility of widgets with operating systems from personal testing:

OS	CPU	Memory	Disks	Temperature	Processes/Search	Networks	Battery
Linux	✓	✓	✓	✓	✓	✓	✓
Windows	✓	✓	✓	? (seems to require elevated access)	✓	✓	✓ (seems to have issues with dual batteries)
macOS	✓	✓	✓	✓	✓ (requires `sudo btm` to show everything)	✓	✓

Other known platform-specific issues

M1-based macOS devices may have issues with temperature sensors not returning anything.
For now, WSL has an issue reporting total memory usage.
WSL and WSL2 (as far as I know) cannot correctly report temperature sensors.
WSL2 will not match Windows' own Task Manager, this appears to be due to how WSL2 works.

Installation

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:

# 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/0.6.1.tar.gz
tar -xzvf 0.6.1.tar.gz
cargo install --path .

Or, you can just download the binary from the latest release.

Nightly

You can install pre-release nightly versions here. Builds are generated every day at 00:00 UTC, based on the most recent commit on the master branch.

Cargo

# 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

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.

Some install scripts (i.e. AUR) will automatically do this for you.

Usage

Run using btm.

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
Display information about disk capacity and I/O per second
Display temperatures from sensors
Display information regarding processes, like CPU, memory, I/O usage, user, 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.

By default, just typing in something will search by process name:

This simple search can be refined by matching by case, matching the entire word, or by using regex:

Now let's say you want to search for two things - luckily, we have the AND and OR logical operators:

Furthermore, one is able to refine their searches by CPU usage, memory usage, PID, and more. For example:

You can see all available keywords and query options here.

Process sorting

You can sort the processes list by any column you want by pressing s while on a process widget:

Tree mode

Use t or F5 to toggle tree mode in a process widget. This is somewhat similar to htop's tree mode.

Sorting works as well, but it is done per groups of siblings. For example, by CPU%:

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:

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.

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):

OS	Location
`~/.config/bottom/bottom.toml` or `$XDG_CONFIG_HOME/bottom/bottom.toml`	Linux
`$HOME/Library/Application Support/bottom/bottom.toml`	macOS
`C:\Users\\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:

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"`

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:

[[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:

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, which contains the default layout.

Furthermore, you can have duplicate widgets. This means you could do something like:

[[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:

Disk, temperature, and network filtering

You can hide specific disks, temperature sensors, and networks by name in the config file via disk_filter and mount_filter, temp_filter, and net_filter respectively. Regex (regex = true), case-sensitivity (case_sensitive = true), and matching only if the entire word matches (whole_word = true) are supported, but are off by default. Filters default to denying entries that match and can be toggled by setting is_list_ignored to false in the config file.

For example, here's the disk widget with no filter:

The following in the config file would filter out some entries by disk name:

[disk_filter]
is_list_ignored = true
list = ["/dev/sda"]
regex = true
case_sensitive = false
whole_word = false

If there are two potentially conflicting filters (i.e. when you are using both a disk and mount filter), the filter that explicitly allows an entry takes precedence over a filter that explicitly denies one. So for example, let's say I set a disk filter accepting anything with /dev/sda, but deny anything with /mnt/.* or /. So to do so, I write in the config file:

[disk_filter]
is_list_ignored = false
list = ["/dev/sda"]
regex = true
case_sensitive = false
whole_word = false

[mount_filter]
is_list_ignored = true
list = ["/mnt/.*", "/"]
regex = true
case_sensitive = false
whole_word = true

Which gives me:

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:

This project is very much inspired by gotop, its successor ytop, and gtop.
Basic mode is heavily inspired by htop's 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!

Process widget sorting by key press bug (simple)
Describe the bug

When entering the process widget and trying to sort by name, it instead sorts by cpu usage.

It seems like the wrong key is binded to it. I tried searching for it for a pull request, but didn't find my way in the repository.

What operating system/architecture are you using?

Arch Linux x86_64

What terminal are you using bottom on?

alacritty as well as the linux shell (no GUI).

What version are you on?

0.6.4

How did you install bottom?

With the official package manager: pacman -S bottom

How can we reproduce this?

In a terminal do:

Open bottom

Press e to enter enlarge process widget.

Press n to sort by name (as hinted at by the TUI).

See it getting sorted by CPU instead.

What is the actual behaviour?

The widget sorts processes by CPU usage.

What is the expected behaviour?

The widget sorts processes by name.

[Bug]: temperature sensors on some arm64 systems are now broken

Checklist

[X] I've looked through troubleshooting, known problems, and existing open issues for similar issues.

Describe the issue

When running bottom on a Radxa Zero, previously I got the cpu temperature sensor, and gpu temperature sensor, now with the switch to just reading hwmon in sysfs, bottom reports No Sensors Found

What operating system are you using?

Linux

What architecture are you using?

arm64

What terminal(s) are you running `bottom` on?

alacritty and windows terminal (ssh'd in to the radxa zero)

What version of `bottom` are you running?

0.6.8 (master at 3d2c40ce2f999e )

How did you install `bottom`?

cargo build --release

How can we reproduce this?

run btm on a radxa zero

Additional information

Perhaps it might be better to look in /sys/devices/virtual/thermal for sensors, or elsewhere. Here's a quick find in sysfs to find all files with temp in the name:

[Bug]: "kinfo_getfile(): No such process" should be silenced
Checklist

[X] I've looked through troubleshooting, known problems, and existing open issues for similar issues.

Describe the issue

One screenshot instead of 100 words: https://s.verknowsys.com/47a2bdcc2adb3e2aa29030340b65eec3.png

The problem is related to the sysinfo crate, the process list fetching routine to be precise. When one of probed process is short lived/ killed/ interrupted or finished when kinfo_getfile() reads info from the process file descriptor.

Details about the syscall: https://www.freebsd.org/cgi/man.cgi?apropos=0&sektion=3&query=kinfo_getfile&manpath=FreeBSD+7.0-current&format=html

A possible solution may be to take control over default error out (/dev/stderr on UNIX*-like) while Bottom is running.

What operating system are you using?

Other (please specify in description)

What architecture are you using?

Other (please specify in description)

What terminal(s) are you running bottom on?

Wezterm

What version of bottom are you running?

master (0.6.x)

How did you install bottom?

from git

How can we reproduce this?

Forget that bottom runs in the background on a busy system :)

Additional information

It happens on all architectures but likely only *BSD have this syscall.

Fine grained kill signals on unix
Description

This PR adds a menu for selecting the signal to send to the selected process when pressing dd in unix.

The signals are aligned in a 8×8 grid, which can be navigated with either the arrow keys, hjkl, or the mouse (if enabled). In addition, number keys can be pressed to quickly jump to the respective signal. On enter, the selected signal is sent to the process and the popup is closed (or no signal is sent if 0: Cancel is selected).

The signal selected by default is 15 (SIGTERM), which is the default signal for killing processes on unix systems.

Issue

Closes: #251

Type of change

[x] New feature (non-breaking change which adds functionality)

Test methodology

Tested on:

[ ] Windows

[ ] macOS

[x] Linux

The feature was tested on Linux. In theory, the original functionality should still be in place for windows builds; however, I was not able to verify this as I could not get the app to run properly on windows in any version (including current master, release branch). I can verify that the build succeeds and the app starts on windows, but the output I get in the terminal (cmd, powershell, git bash) of my (virtual) machine (win7) is garbled, and I sadly don't have any other versions of windows to test with (according to the documentation of crossterm, it should work on win7...).

Checklist

[x] Change has been tested to work, and does not cause new breakage unless intended

[x] Code has been self-reviewed

[x] Passes Travis tests (clippy check and cargo test check)

[x] Areas your change affects have been linted using rustfmt (cargo fmt)

[x] No merge conflicts arise from the change

CPU/Memory Usage seems to have gone up considerably compared to earlier versions
Describe the bug

Previous versions, 0.4.x I think, versions seemed to use a lot less CPU than 0.5.3 does. Especially as time goes on, I find btm at the top of the processes list, when it never was before.

A bit ago it was using a whole 5%, and now seems to have settled on about 3%, which is still far more than any other single process on the system right now. The various chrome processes, Xorg, kwin, etc use about 0.1% each, for reference.

I also just noticed it's using 185 MiB of memory, which is a lot more than it should be.

These CPU/memory usage issues seems to get worse as time goes on. The way I use bottom, I leave it open on my terminal.

When freshly, started it uses a more reasonable 0.2% CPU and 13 MiB of memory.

To reproduce

Run btm

Monitor its CPU/Memory usage

Wait

bottom version (use btm -V)

bottom 0.5.3

bottom config file (if one is used)

Installation method

Cargo install

Platform

Operating system and OS version: Arch Linux, rolling.

Terminal (i.e. urxvt, kitty, etc.): Yakuake/Konsole

Shell (i.e. zsh, bash, etc.): Fish

If relevant, please provide information on:

System info (RAM, SWAP, etc.): 16 GB RAM, AMD Ryzen 5 2600 CPU

Rust version (if building yourself): rustc 1.48.0

Additional context

Yakuake is a tabbed drop-down KDE Konsole terminal, so I leave bottom open on it so I can quickly view system information at the push of a hotkey.

Don't know exact numbers for it to build up. Current system uptime is 2 days, with bottom likely open the whole time. I've gone longer but havent seen it go to absolutely insane levels, maybe it plateaus, or maybe its just really slow and I notice its high usage and restart it often enough that it doesnt eat everything?

macOS M1 support
Describe the feature request

What is the feature of interest? Be clear and concise.

Adding support for the M1 processor is a good idea, especially if/when it becomes a tier-1 target and has better tooling to work around it.

Currently I can't exactly test for these, or need to wait for upstream support on libraries I rely on, though.

Currently not working on M1:

[Feature] Improving in-app documentation and help
Checklist

[X] I've looked through the documentation and existing open issues for this feature/feature request.

Describe the feature request

There's a lot of instances where a question about how to do something simple in bottom can be answered by "look at the docs online" (e.g. a feature exists at all, how to use it, etc.) However, this is, IMO, not a great solution. While it is definitely a good place to put more detailed solutions/answers/things that don't naturally fit (e.g. troubleshooting steps, supported systems, etc.), the in-app documentation/help leaves a lot to be desired.

Some of it can be improved by things like finishing #159, but doing a lookthrough at the ? help menu and cleaning things up in clap/overall can probably help.

It might also help to add a toggleable "bar" a la htop/top that gives useful keybindings.
