You can hide specific disks, temperature sensors, and networks by name in the config file via disk.name_filter and disk.mount_filter, temperature.sensor_filter, and network.interface_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.name_filter]\nis_list_ignored = true\nlist = [\"/dev/sda\"]\nregex = true\ncase_sensitive = false\nwhole_word = false\nIf 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 we set a disk filter accepting anything with /dev/sda, but deny anything with /mnt/.* or /. So to do so, we write in the config file:
[disk.name_filter]\nis_list_ignored = false\nlist = [\"/dev/sda\"]\nregex = true\ncase_sensitive = false\nwhole_word = false\n\n[disk.mount_filter]\nis_list_ignored = true\nlist = [\"/mnt/.*\", \"/\"]\nregex = true\ncase_sensitive = false\nwhole_word = true\nThis gives us:

This section is in progress, and is just copied from the old documentation.
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]]\n [[row.child]]\n type=\"cpu\"\n[[row]]\n ratio=2\n [[row.child]]\n ratio=4\n type=\"mem\"\n [[row.child]]\n ratio=3\n [[row.child.child]]\n type=\"temp\"\n [[row.child.child]]\n type=\"disk\"\nThis 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.
Furthermore, you can have duplicate widgets.
For an example, look at the default config, which contains the default layout.

Where you're adding documentation will probably affect what you need to do:
README.md or CHANGELOG.md For changes to README.md and CHANGELOG.md, just follow the formatting provided and use any editor.
Generally, changes to CHANGELOG.md will be handled by a maintainer, and the contents of the file should follow the Keep a Changelog format, as well as link to the relevant PR or issues.
For changes to the help menu, try to refer to the existing code within src/constants.rs on how the help menu is generated.
For changes to the extended documentation, you'll probably want at least Python 3.11 (older and newer versions should be fine), MkDocs, Material for MkDocs, mdx_truly_sane_lists, and optionally Mike installed. These can help with validating your changes locally.
You can do so through pip or your system's package managers. If you use pip, you can use venv to cleanly install the documentation dependencies:
# Change directories to the documentation.\ncd docs/\n\n # Create venv, install the dependencies, and serve the page.\n./serve.sh\nThis will serve a local version of the docs that you can open on your browser. It will update as you make changes.
Once you have your documentation changes done, submit it as a pull request. For more information regarding that, refer to Issues, Pull Requests, and Discussions.
Discussions are open in the repo. As for the difference between discussions and issues:
When filing a bug report, please use the bug report template and fill in as much as you can. It is incredibly difficult for a maintainer to fix a bug when it cannot be reproduced, and giving as much detail as possible generally helps to make it easier to reproduce the problem!

You can also find a nightly build in the releases page, built every day at 00:00 UTC off of the main branch.
In both cases, we use a combination of GitHub Actions and CirrusCI (mainly for FreeBSD and macOS M1) to create our release binaries. build_releases.yml contains the GitHub Action workflow used to do both of these, if reference is needed.
If you want to manually build bottom rather than distributing a pre-built binary, you'll need the most recent version of stable Rust, which you can get with:
rustup update stable\nYou'll then want to build with:
cargo build --release --locked\nbottom uses a build.rs script to automatically generate a manpage and shell completions for the following shells:
If you want to generate manpages and/or completion files, set the BTM_GENERATE env var to a non-empty value. For example, run something like this:
BTM_GENERATE=true cargo build --release --locked\nThis will automatically generate completion and manpage files in target/tmp/bottom/. If you wish to regenerate the files, modify/delete either these files or set BTM_GENERATE to some other non-empty value to retrigger the build script.
For more information, you may want to look at either the build.rs file or the binary build CI workflow.
Once you've finished your installation source, if you want to mention it in the main bottom repo, fork the repo and add the installation method and any details to the README.md file under the Installation section, as well as a corresponding table of contents entry. Once that's done, open a pull request - these will usually be approved of very quickly.

You can hide specific disks, temperature sensors, and networks by name in the config file via disk.name_filter and disk.mount_filter, temperature.sensor_filter, and network.interface_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.name_filter]\nis_list_ignored = true\nlist = [\"/dev/sda\"]\nregex = true\ncase_sensitive = false\nwhole_word = false\nIf 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 we set a disk filter accepting anything with /dev/sda, but deny anything with /mnt/.* or /. So to do so, we write in the config file:
[disk.name_filter]\nis_list_ignored = false\nlist = [\"/dev/sda\"]\nregex = true\ncase_sensitive = false\nwhole_word = false\n\n[disk.mount_filter]\nis_list_ignored = true\nlist = [\"/mnt/.*\", \"/\"]\nregex = true\ncase_sensitive = false\nwhole_word = true\nThis gives us:

This section is in progress, and is just copied from the old documentation.
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]]\n [[row.child]]\n type=\"cpu\"\n[[row]]\n ratio=2\n [[row.child]]\n ratio=4\n type=\"mem\"\n [[row.child]]\n ratio=3\n [[row.child.child]]\n type=\"temp\"\n [[row.child.child]]\n type=\"disk\"\nThis 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.
Furthermore, you can have duplicate widgets.
For an example, look at the default config, which contains the default layout.

Where you're adding documentation will probably affect what you need to do:
README.md or CHANGELOG.md For changes to README.md and CHANGELOG.md, just follow the formatting provided and use any editor.
Generally, changes to CHANGELOG.md will be handled by a maintainer, and the contents of the file should follow the Keep a Changelog format, as well as link to the relevant PR or issues.
For changes to the help menu, try to refer to the existing code within src/constants.rs on how the help menu is generated.
For changes to the extended documentation, you'll probably want at least Python 3.11 (older and newer versions should be fine), MkDocs, Material for MkDocs, mdx_truly_sane_lists, and optionally Mike installed. These can help with validating your changes locally.
You can do so through pip or your system's package managers. If you use pip, you can use venv to cleanly install the documentation dependencies:
# Change directories to the documentation.\ncd docs/\n\n # Create venv, install the dependencies, and serve the page.\n./serve.sh\nThis will serve a local version of the docs that you can open on your browser. It will update as you make changes.
Once you have your documentation changes done, submit it as a pull request. For more information regarding that, refer to Issues, Pull Requests, and Discussions.
Discussions are open in the repo. As for the difference between discussions and issues:
When filing a bug report, please use the bug report template and fill in as much as you can. It is incredibly difficult for a maintainer to fix a bug when it cannot be reproduced, and giving as much detail as possible generally helps to make it easier to reproduce the problem!

You can also find a nightly build in the releases page, built every day at 00:00 UTC off of the main branch.
In both cases, we use a combination of GitHub Actions and CirrusCI (mainly for FreeBSD and macOS M1) to create our release binaries. build_releases.yml contains the GitHub Action workflow used to do both of these, if reference is needed.
If you want to manually build bottom rather than distributing a pre-built binary, you'll need the most recent version of stable Rust, which you can get with:
rustup update stable\nYou'll then want to build with:
cargo build --release --locked\nbottom uses a build.rs script to automatically generate a manpage and shell completions for the following shells:
If you want to generate manpages and/or completion files, set the BTM_GENERATE env var to a non-empty value. For example, run something like this:
BTM_GENERATE=true cargo build --release --locked\nThis will automatically generate completion and manpage files in target/tmp/bottom/. If you wish to regenerate the files, modify/delete either these files or set BTM_GENERATE to some other non-empty value to retrigger the build script.
For more information, you may want to look at either the build.rs file or the binary build CI workflow.
Once you've finished your installation source, if you want to mention it in the main bottom repo, fork the repo and add the installation method and any details to the README.md file under the Installation section, as well as a corresponding table of contents entry. Once that's done, open a pull request - these will usually be approved of very quickly.

If you're on Windows, or if the disable_advanced_kill flag is set in the options or command-line, then a simpler termination screen will be shown to confirm whether you want to kill that process/process group.
Pressing t or F5 in the table toggles tree mode in the process widget, displaying processes in regard to their parent-child process relationships.
A process in tree mode can also be \"collapsed\", hiding its children and any descendants, using either the - or + keys, or double-clicking on an entry.
Lastly, note that in tree mode, processes cannot be grouped together due to the behaviour of the two modes somewhat clashing.

This search can be further enhanced by matching by case, matching the entire word, or by regex.
We are able to also search for multiple things/conditions.
And if our search uses a keyword, we need to use quotation marks around the term to properly search it.
Lastly, we can refine our search even further based on the other columns, like PID, CPU usage, etc., as well as grouping together conditions.
You can also paste search queries (e.g. Shift+Ins, Ctrl+Shift+v).
