Project Status: Active – The project has reached a stable, usable state and is being actively developed. GitHub CI Hackage Stackage LTS Stackage Nightly


bm is a utility for opening bookmarks and queries from the command line. The bookmarks and queries are configured hierarchically in YAML, and they are referenced using keyword prefixes. It allows you to quickly open bookmarks and perform search queries in your browser using only your keyboard.



bm is designed to work on any operating system, but it has only been tested on Linux.


.deb Package Installation

Check the Releases page for .deb packages.

.rpm Package Installation

Check the Releases page for .rpm packages.

Installation From Hackage

Install bm from Hackage using Cabal as follows:

$ cabal v2-install bm

Installation From Stackage

Install bm from Stackage using Stack as follows:

$ stack install bm


Bookmarks and search queries are configured using a hierarchy of keywords in a YAML configuration file. They are selected using keyword prefixes as command-line arguments. Command-line completion is available for Bash. See the bm man page for details.

Note that the command used to open bookmarks and queries can be customized in the configuration file. Specifying the command for your specific browser can make links open considerably faster than with the default (generic) command.


An example configuration file is available in the config directory on GitHub (example for the latest release: bm.yaml). The following are example commands using this configuration file.

Open a bookmark link by specifying keywords. The Nix homepage can be opened with the following command:

$ bm nix

The nixpkgs manual can be opened using the following command:

$ bm nix pkgs manual

Keyword prefixes can also be used. The following command also opens the nixpkgs manual:

$ bm n p m

When more than one keyword has the same prefix, the first is selected. If a selected bookmark does not specify a URL, the first child is processed.

The / keyword defines a bookmark with a URL as well as a query. When no query is specified, the URL is opened, allowing you to search with suggestions using the search field. Open a query by specifying keywords followed by the query.

$ bm / LinearTypes

When multiple query arguments are provided, they are joined with a space.



The main branch is reserved for releases. It may be considered stable, and HEAD is always the latest release.

The develop branch is the primary development branch. It contains changes that have not yet been released, and it is not necessarily stable.

Hackage revisions are made for metadata changes, such as relaxation of constraints when new versions of dependencies are released. The bm.cabal metadata in the main branch may therefore not match that of Hackage. The bm.cabal metadata in the develop branch may match, unless work is being done on a new release that contains other changes.


All releases are tagged in the main branch. Release tags are signed using the GPG key.
