PowerShell scripts can be created within PowerShell Universal to execute manually, on a scheudle or when events happen within the platform. They are stored on disk and also persisted to a local or remote Git repository.
Script properties are stored in the scripts.ps1 configuration file.
To add a new script, you can click the New Script button within the Automation / Scripts page. There are various settings you can provide for the script.
Name of the script as shown in Universal Automation. This will also be the name used to persist the script to disk. This setting needs to be unique within the current folder.
A description of the script. This is shown in various places within the UA UI and also returned by the Universal cmdlets.
Prevents a script from being run manually. This is enforced in the UI as well as the web server and cmdlets.
This setting is used to track the amount of time saved.
Defaults to 100. It defines the amount of jobs that are stored when running this script. Jobs are also cleaned up based on the server-wide job retention duration setting from within the Settings / General page.
Changes how the script reacts when there is an error within the script. By default, terminating and non-terminating errors are ignored and the script will always be successful. You can change this setting to stop to cause scripts to fail immediately when an error is encountered.
Allows you to define the required PowerShell environment for the script. By default, it uses the server-wide default PowerShell environment. PowerShell environments are automatically located the first the Universal Server starts up or read from the environments.ps1 file. You can also add Environment on the Settings / Environments page.
The number of minutes before the script will timeout. The default value of 0 means the script will run forever. Once a script reaches it's time out, it will be cancelled.
The anonymous setting allows the script to be run when the user is not authenticated. This is useful when using scripts in Pages.
Available in PowerShell Universal 2.8 or later.
When checked, this will disable the storage of pipeline output. This will greatly reduce the CPU and storage overhead of jobs. The script will still write to the information, warning, and error streams.
Defines the maximum concurrent jobs the script can be run. Defaults to 100.
You can run a script in the UI by click the Run button the Automation / Scripts page or by clicking View and then Run. In each case, you will be presented with the Run Dialog that allows you to select various settings for the job.

PowerShell Universal automatically determines the parameters as defined within your scripts. It takes advantage of static code analysis to determine the type, default values and some validation that is then presented within the UI.
For example, you may have a script with the following parameters.
The result is a set of input options that are based on the types of parameters.
The integrated environment does not support running as alternate credentials.
You can run scripts as another user by configuring secret variables. PowerShell Universal uses the Microsoft Secret Management module to integrate with secret providers. See variables for more information on secrets.
To run as another user, simply add or import a PSCredential variable. From there, you can select the credential from within the run dialog.
Note that you can use PowerShell remoting by taking advantage of Invoke-Command . We do not support the use of Enter-PSSession or Import-PSSession.
This feature is available in PowerShell Universal 2.5 or later.
You can use comment-based to define the description, a synopsis, parameter based help, and links for your scripts. These will be displayed within the PowerShell Universal UI.
This above will yield the following user interface. The synopsis will be shown as the short description and a longer description can be shown in the description section. Links will appear under the description.
