How to use the ZeroNorth™ Command-Line Interface (CLI) and download


The steps described in this article assume that you have:

  • ZeroNorth License and Credentials
  • Access to ZeroNorth and the Scanning tools
  • Platform supported by our CLI executable


  • Windows: zn_cli.exe [options] [options] ...
  • Ubuntu: zn_cli [options] [options] ...

To see a complete list of the options, run zn_cli.exe --help :


On some operating systems, it will be necessary to set the following two environment variables:

export LC_ALL=en_US.utf-8
export LANG=en_US.utf-8


export LC_ALL=C.UTF-8
export LANG=C.UTF-8

The CLI will need to use a temporary folder for zipping up the contents of the folder pointed to by the --code_path parameter. Specific to Unix/Linux, the default location for this is /tmp and is irrespective of what value you set for the --results_path parameter. To override the location of the temporary folder, set the environmental variable TMP to the desired location:

export TMP=/home/myhome/tmp


set TMP="C:\Temp"

In PowerShell:



Below are couple of examples:

1) Scanning the WebGoat project using WhiteSource:

zn_cli.exe --api_key <your ZeroNorth API token> --code_path c:\GitHub\WebGoat\ --results_path c:\Temp\ --policy_id <ZeroNorth policy ID>


  • The command syntax for the Linux variants of CLI is identical, except for the use of the forward slashes ("/") in the paths.
  • The Windows command syntax can also accept forward slashes in the paths, assuming you are running the executable from the same drive (e.g. “C:”) as where the scan target is.
  • In Windows, you should always use the trailing [back] slash for the code_path parameter value. For example: c:\myworkdir\myproject\ , not c:\myworkdir\myproject .
  • We always recommend the use of the api_key option instead of username and password. See the article Obtaining your ZeroNorth API Token for information on obtaining your API token.

2) Scanning the WebGoat project using SonarQube

SonarQube scans require additional parameters when the target project is a Java project:

zn_cli.exe --api_key <your ZeroNorth api token> --code_path c:\GitHub\WebGoat\ --results_path c:\Temp\ --scenario sonarqube-agent --sonar_java_library_dir "webgoat-container/target/classes/static/js/libs,webgoat-container/src/main/resources/static/js/libs" --sonar_java_binary_dir "webwolf,webgoat-container,webgoat-lessons,webgoat-server" --policy_name WebGoat-SQ-Scan


  • sonar_java_library_dir is a comma-separated list of folders within the project that contain all of the project’s library files (e.g. .jar files). These paths must be specified using forward slashes ("/’) relative to the project root.
  • sonar_java_binary_dir is a comma-separated list of folders within the project that contain all of the project’s compiled binaries (e.g. .class files). These paths must be specified using forward slashes ("/’) relative to the project root
  • policy_name when specified, will be used in naming the auto-created policy. Alternatively, use policy_id to specify an existing policy. See the article Manage Security Policies for instructions on obtaining a policy_id.

3) Using the CLI to dynamically auto-create the Target and the Policy for an upload/scan use case

In this use case, you let the CLI to automatically create the necessary Target and the appropriate Policy for you. This is useful when you are integrating the CLI into many similar CI/CD pipelines and you want to eliminate the need to manually create the Target and the Policy in advance.

We use the WebGoat / WhiteSource example from above, but with modifications:

zn_cli.exe --api_key ..... --code_path c:\GitHub\WebGoat\ --results_path c:\Temp\ --scenario MyWSScenarioName --target_name WebGoatBuild --policy_name WebGoatBuild_WS


  • The named Scenario must already exist in your ZeroNorth account.
  • The named Target and Policy will be dynamically created using the following rules:
    1. IF no match THEN create the object using the specified name
    2. IF more than one match THEN die
    3. IF exactly one match THEN (re)use that object
  • By default, the CLI will perform a build artifact upload/scan.

Viewing Results

  • Use ZeroNorth’s web UI to view your scan results.
  • You can also see the raw output in the scan.out file within the folder specified via the results_path parameter.
