NAME
zkg - Zeek Package Manager

A command-line package manager for Zeek.

    usage: zkg [-h] [--version] [--configfile FILE | --user] [--verbose] [--extra-source NAME=URL]
               {test,install,bundle,unbundle,remove,uninstall,purge,refresh,upgrade,load,unload,pin,unpin,list,search,info,config,autoconfig,env,create,template} ...

Options:

--version
    show program's version number and exit

--configfile
    Path to Zeek Package Manager config file. Precludes --user.

    See Config File.

--user=False
    Store all state in user's home directory. Precludes --configfile.

--verbose=0, -v=0
    Increase program output for debugging. Use multiple times for more output (e.g. -vv).

--extra-source
    Add an extra source.

    Environment Variables:
    ZKG_CONFIG_FILE:    Same as --configfile option, but has less precedence.
    ZKG_DEFAULT_SOURCE:    The default package source to use (normally https://github.com/zeek/packages).
    ZKG_DEFAULT_TEMPLATE:    The default package template to use (normally https://github.com/zeek/package-template).

COMMANDS

  test

Runs the unit tests for the specified Zeek packages. In most cases, the "zeek" and "zeek-config" programs will need to be in PATH before running this command.

    usage: zkg test [-h] [--version VERSION] package [package ...]

Positional arguments:

package
    The name(s) of package(s) to operate on. The package may be named in several ways. If the package is part of a package source, it may be referred to by the base name of the package (last component of git URL) or its path within the package source. If two packages in different package sources have conflicting paths, then the package source name may be prepended to the package path to resolve the ambiguity. A full git URL may also be used to refer to a package that does not belong to a source. E.g. for a package source called "zeek" that has a package named "foo" located in "alice/zkg.index", the following names work: "foo", "alice/foo", "zeek/alice/foo".

Options:

--version
    The version of the package to test. Only one package may be specified at a time when using this flag. A version tag, branch name, or commit hash may be specified here. If the package name refers to a local git repo with a working tree, then its currently active branch is used. The default for other cases is to use the latest version tag, or if a package has none, the default branch, like "main" or "master".

  install

Installs packages from a configured package source or directly from a git URL. After installing, the package is marked as being "loaded" (see the load command).

    usage: zkg install [-h] [--skiptests] [--nodeps] [--nosuggestions] [--version VERSION] [--force] [--user-var NAME=VAL] package [package ...]

Positional arguments:

package
    The name(s) of package(s) to operate on. The package may be named in several ways. If the package is part of a package source, it may be referred to by the base name of the package (last component of git URL) or its path within the package source. If two packages in different package sources have conflicting paths, then the package source name may be prepended to the package path to resolve the ambiguity. A full git URL may also be used to refer to a package that does not belong to a source. E.g. for a package source called "zeek" that has a package named "foo" located in "alice/zkg.index", the following names work: "foo", "alice/foo", "zeek/alice/foo".

Options:

--skiptests=False
    Skip running unit tests for packages before installation.

--nodeps=False
    Skip all dependency resolution/checks. Note that using this option risks putting your installed package collection into a broken or unusable state.

--nosuggestions=False
    Skip automatically installing suggested packages.

--version
    The version of the package to install. Only one package may be specified at a time when using this flag. A version tag, branch name, or commit hash may be specified here. If the package name refers to a local git repo with a working tree, then its currently active branch is used. The default for other cases is to use the latest version tag, or if a package has none, the default branch, like "main" or "master".

--force=False
    Don't prompt for confirmation or user variables.

--user-var
    A user variable assignment. This avoids prompting for input and lets you provide a value when using --force. Use repeatedly as needed for multiple values.

  remove

Unloads (see the unload command) and uninstalls a previously installed package.

    usage: zkg remove [-h] [--force] [--nodeps] package [package ...]

Positional arguments:

package
    The name(s) of package(s) to operate on. The package may be named in several ways. If the package is part of a package source, it may be referred to by the base name of the package (last component of git URL) or its path within the package source. If two packages in different package sources have conflicting paths, then the package source name may be prepended to the package path to resolve the ambiguity. A full git URL may also be used to refer to a package that does not belong to a source. E.g. for a package source called "zeek" that has a package named "foo" located in "alice/zkg.index", the following names work: "foo", "alice/foo", "zeek/alice/foo".

Options:

--force=False
    Skip the confirmation prompt.

--nodeps=False
    Skip all dependency resolution/checks. Note that using this option risks putting your installed package collection into a broken or unusable state.

    NOTE: You may also say uninstall.

  purge

Unloads (see the unload command) and uninstalls all previously installed packages.

    usage: zkg purge [-h] [--force]

Options:

--force=False
    Skip the confirmation prompt.

  bundle

This command creates a bundle file containing a collection of Zeek packages. If --manifest is used, the user supplies the list of packages to put in the bundle, else all currently installed packages are put in the bundle. A bundle file can be unpacked on any target system, resulting in a repeatable/specific set of packages being installed on that target system (see the unbundle command). This command may be useful for those that want to manage packages on a system that otherwise has limited network connectivity. E.g. one can use a system with an internet connection to create a bundle, transport that bundle to the target machine using whatever means are appropriate, and finally unbundle/install it on the target machine.

    usage: zkg bundle [-h] [--force] [--nodeps] [--nosuggestions] [--manifest MANIFEST [MANIFEST ...] --] filename.bundle

Positional arguments:

filename.bundle
    The path of the bundle file to create. It will be overwritten if it already exists. Note that if --manifest is used before this filename is specified, you should use a double-dash, --, to first terminate that argument list.

Options:

--force=False
    Skip the confirmation prompt.

--nodeps=False
    Skip all dependency resolution/checks. Note that using this option risks creating a bundle of packages that is in a broken or unusable state.

--nosuggestions=False
    Skip automatically bundling suggested packages.

--manifest
    This may either be a file name or a list of packages to include in the bundle. If a file name is supplied, it should be in INI format with a single ``[bundle]`` section. The keys in that section correspond to package names and their values correspond to git version tags, branch names, or commit hashes. The values may be left blank to indicate that the latest available version should be used.

  unbundle

This command unpacks a bundle file formerly created by the bundle command and installs all the packages contained within.

    usage: zkg unbundle [-h] [--replace] [--force] [--user-var NAME=VAL] filename.bundle

Positional arguments:

filename.bundle
    The path of the bundle file to install.

Options:

--replace=False
    Using this flag first removes all installed packages before then installing the packages from the bundle.

--force=False
    Don't prompt for confirmation or user variables.

--user-var
    A user variable assignment. This avoids prompting for input and lets you provide a value when using --force. Use repeatedly as needed for multiple values.

  refresh

Retrieve latest package metadata from sources and checks whether any installed packages have available upgrades. Note that this does not actually upgrade any packages (see the upgrade command for that).

    usage: zkg refresh [-h] [--aggregate] [--fail-on-aggregate-problems] [--push] [--sources SOURCES [SOURCES ...]]

Options:

--aggregate=False
    Crawls the urls listed in package source zkg.index files and aggregates the metadata found in their zkg.meta (or legacy bro-pkg.meta) files. The aggregated metadata is stored in the local clone of the package source that zkg uses internally for locating package metadata. For each package, the metadata is taken from the highest available git version tag or the default branch, like "main" or "master", if no version tags exist

--fail-on-aggregate-problems=False
    When using --aggregate, exit with error when any packages trigger metadata problems. Normally such problems only cause a warning.

--push=False
    Push all local changes to package sources to upstream repos

--sources
    A list of package source names to operate on. If this argument is not used, then the command will operate on all configured sources.

  upgrade

Uprades the specified package(s) to latest available version. If no specific packages are specified, then all installed packages that are outdated and not pinned are upgraded. For packages that are installed with --version using a git branch name, the package is updated to the latest commit on that branch, else the package is updated to the highest available git version tag.

    usage: zkg upgrade [-h] [--skiptests] [--nodeps] [--nosuggestions] [--force] [--user-var NAME=VAL] [package ...]

Positional arguments:

package
    The name(s) of package(s) to operate on. The package may be named in several ways. If the package is part of a package source, it may be referred to by the base name of the package (last component of git URL) or its path within the package source. If two packages in different package sources have conflicting paths, then the package source name may be prepended to the package path to resolve the ambiguity. A full git URL may also be used to refer to a package that does not belong to a source. E.g. for a package source called "zeek" that has a package named "foo" located in "alice/zkg.index", the following names work: "foo", "alice/foo", "zeek/alice/foo".

Options:

--skiptests=False
    Skip running unit tests for packages before installation.

--nodeps=False
    Skip all dependency resolution/checks. Note that using this option risks putting your installed package collection into a broken or unusable state.

--nosuggestions=False
    Skip automatically installing suggested packages.

--force=False
    Don't prompt for confirmation or user variables.

--user-var
    A user variable assignment. This avoids prompting for input and lets you provide a value when using --force. Use repeatedly as needed for multiple values.

  load

The Zeek Package Manager keeps track of all packages that are marked as "loaded" and maintains a single Zeek script that, when loaded by Zeek (e.g. via @load packages), will load the scripts from all "loaded" packages at once. This command adds a set of packages to the "loaded packages" list.

    usage: zkg load [-h] [--nodeps] package [package ...]

Positional arguments:

package
    Name(s) of package(s) to load.

Options:

--nodeps=False
    Skip all dependency resolution/checks. Note that using this option risks putting your installed package collection into a broken or unusable state.

  unload

The Zeek Package Manager keeps track of all packages that are marked as "loaded" and maintains a single Zeek script that, when loaded by Zeek, will load the scripts from all "loaded" packages at once. This command removes a set of packages from the "loaded packages" list.

    usage: zkg unload [-h] [--force] [--nodeps] package [package ...]

Positional arguments:

package
    The name(s) of package(s) to operate on. The package may be named in several ways. If the package is part of a package source, it may be referred to by the base name of the package (last component of git URL) or its path within the package source. If two packages in different package sources have conflicting paths, then the package source name may be prepended to the package path to resolve the ambiguity. A full git URL may also be used to refer to a package that does not belong to a source. E.g. for a package source called "zeek" that has a package named "foo" located in "alice/zkg.index", the following names work: "foo", "alice/foo", "zeek/alice/foo".

Options:

--force=False
    Skip the confirmation prompt.

--nodeps=False
    Skip all dependency resolution/checks. Note that using this option risks putting your installed package collection into a broken or unusable state.

  pin

Pinned packages are ignored by the upgrade command.

    usage: zkg pin [-h] package [package ...]

Positional arguments:

package
    The name(s) of package(s) to operate on. The package may be named in several ways. If the package is part of a package source, it may be referred to by the base name of the package (last component of git URL) or its path within the package source. If two packages in different package sources have conflicting paths, then the package source name may be prepended to the package path to resolve the ambiguity. A full git URL may also be used to refer to a package that does not belong to a source. E.g. for a package source called "zeek" that has a package named "foo" located in "alice/zkg.index", the following names work: "foo", "alice/foo", "zeek/alice/foo".

  unpin

Packages that are not pinned are automatically upgraded by the upgrade command

    usage: zkg unpin [-h] package [package ...]

Positional arguments:

package
    The name(s) of package(s) to operate on. The package may be named in several ways. If the package is part of a package source, it may be referred to by the base name of the package (last component of git URL) or its path within the package source. If two packages in different package sources have conflicting paths, then the package source name may be prepended to the package path to resolve the ambiguity. A full git URL may also be used to refer to a package that does not belong to a source. E.g. for a package source called "zeek" that has a package named "foo" located in "alice/zkg.index", the following names work: "foo", "alice/foo", "zeek/alice/foo".

  list

Outputs a list of packages that match a given category.

    usage: zkg list [-h] [--nodesc] [--include-builtin] [{all,installed,not_installed,loaded,unloaded,outdated}]

Positional arguments:

category
    Package category used to filter listing.

    Possible choices: all, installed, not_installed, loaded, unloaded, outdated

Options:

--nodesc=False
    Do not display description text, just the package name(s).

--include-builtin=False
    Also output packages that Zeek has built-in. By default these are not shown.

  search

Perform a substring search on package names and metadata tags. Surround search text with slashes to indicate it is a regular expression (e.g. /text/).

    usage: zkg search [-h] search_text [search_text ...]

Positional arguments:

search_text
    The text(s) or pattern(s) to look for.

  info

Shows detailed information/metadata for given packages. If the package is currently installed, additional information about the status of it is displayed. E.g. the installed version or whether it is currently marked as "pinned" or "loaded."

    usage: zkg info [-h] [--version VERSION] [--nolocal] [--include-builtin] [--json] [--jsonpretty SPACES] [--allvers] package [package ...]

Positional arguments:

package
    The name(s) of package(s) to operate on. The package may be named in several ways. If the package is part of a package source, it may be referred to by the base name of the package (last component of git URL) or its path within the package source. If two packages in different package sources have conflicting paths, then the package source name may be prepended to the package path to resolve the ambiguity. A full git URL may also be used to refer to a package that does not belong to a source. E.g. for a package source called "zeek" that has a package named "foo" located in "alice/zkg.index", the following names work: "foo", "alice/foo", "zeek/alice/foo". If a single name is given and matches one of the same categories as the "list" command, then it is automatically expanded to be the names of all packages which match the given category.

Options:

--version
    The version of the package metadata to inspect. A version tag, branch name, or commit hash and only one package at a time may be given when using this flag. If unspecified, the behavior depends on whether the package is currently installed. If installed, the metadata will be pulled from the installed version. If not installed, the latest version tag is used, or if a package has no version tags, the default branch, like "main" or "master", is used.

--nolocal=False
    Do not read information from locally installed packages. Instead read info from remote GitHub.

--include-builtin=False
    Also output packages that Zeek has built-in. By default these are not shown.

--json=False
    Output package information as JSON.

--jsonpretty
    Optional number of spaces to indent for pretty-printed JSON output.

--allvers=False
    When outputting package information as JSON, show metadata for all versions. This option can be slow since remote repositories may be cloned multiple times. Also, installed packages will show metadata only for the installed version unless the --nolocal option is given.

  config

The default output of this command is a valid package manager config file that corresponds to the one currently being used, but also with any defaulted field values filled in. This command also allows for only the value of a specific field to be output if the name of that field is given as an argument to the command.

    usage: zkg config [-h] [{all,sources,user_vars,state_dir,script_dir,plugin_dir,bin_dir,zeek_dist}]

Positional arguments:

config_param
    Name of a specific config file field to output.

    Possible choices: all, sources, user_vars, state_dir, script_dir, plugin_dir, bin_dir, zeek_dist

  autoconfig

The output of this command is a valid package manager config file that is generated by using the zeek-config script that is installed along with Zeek. It is the suggested configuration to use for most Zeek installations. For this command to work, the zeek-config script must be in PATH, unless the --user option is given, in which case this creates a config that does not touch the Zeek installation.

    usage: zkg autoconfig [-h] [--force]

Options:

--force=False
    Skip any confirmation prompt.

  env

This command returns shell commands that, when executed, will correctly set ZEEKPATH and ZEEK_PLUGIN_PATH to use scripts and plugins from packages installed by the package manager. For this command to function properly, either have the zeek-config script (installed by zeek) in PATH, or have the ZEEKPATH and ZEEK_PLUGIN_PATH environment variables already set so this command can append package-specific paths to them.

    usage: zkg env [-h]

  create

This command creates a new Zeek package in the directory provided via --packagedir. If this directory exists, zkg will not modify it unless you provide --force.

    usage: zkg create [-h] --packagedir DIR [--version VERSION] [--features FEATURE [FEATURE ...]] [--template URL] [--force] [--user-var NAME=VAL]

Options:

--packagedir
    Output directory into which to produce the new package. Required.

--version
    The template version to use. A version tag, branch name, or commit hash may be specified here. If --template refers to a local git repo with a working tree, then zkg uses it as-is and the version is ignored. The default for other cases is to use the latest version tag, or if a template has none, the default branch, like "main" or "master".

--features
    Additional features to include in your package. Use the ``template info`` command for information about available features.

--template
    By default, zkg uses its own package template. This makes it select an alternative.

--force=False
    Don't prompt for confirmation or user variables.

--user-var
    A user variable assignment. This avoids prompting for input and lets you provide a value when using --force. Use repeatedly as needed for multiple values.

  template info

This command shows versions and supported features for a given package.

    usage: zkg template info [-h] [--json] [--jsonpretty SPACES] [--version VERSION] [URL]

Positional arguments:

URL URL of a package template repository, or local path to one. When not provided, the configured default template is used.

Options:

--json=False
    Output template information as JSON.

--jsonpretty
    Optional number of spaces to indent for pretty-printed JSON output.

--version
    The template version to report on. A version tag, branch name, or commit hash may be specified here. If the selected template refers to a local git repo, the version is ignored. The default for other cases is to use the latest version tag, or if a template has none, the default branch, like "main" or "master".

CONFIG FILE

The zkg command-line tool uses an INI-format config file to allow users to customize their Package Sources, Package installation paths, Zeek executable/source paths, and other zkg options.

See the default/example config file below for explanations of the available options and how to customize them:

    # This is an example config file for zkg to explain what
    # settings are possible as well as their default values.
    # The order of precedence for how zkg finds/reads config files:
    #
    # (1) zkg --configfile=/path/to/custom/config
    # (2) the ZKG_CONFIG_FILE environment variable
    # (3) a config file located at $HOME/.zkg/config
    # (4) if none of the above exist, then zkg uses builtin/default
    #     values for all settings shown below
    [sources]
    # The default package source repository from which zkg fetches
    # packages.  The default source may be removed, changed, or
    # additional sources may be added as long as they use a unique key
    # and a value that is a valid git URL.  The git URL may also use a
    # suffix like "@branch-name" where "branch-name" is the name of a real
    # branch to checkout (as opposed to the default branch, which is typically
    # "main" or "master"). You can override the package source zkg puts
    # in new config files (e.g. "zkg autoconfig")  by setting the
    # ZKG_DEFAULT_SOURCE environment variable.
    zeek = https://github.com/zeek/packages
