Create a Universal Template, which includes selecting the type of Agent(s) on which Universal Tasks based on this Universal Template can be run, and a variable prefix used for script variables that you want resolved when a Universal Task executes the script in this Universal Template.

Enter a script in the Universal Template that all Universal Tasks based on this Universal Template will execute when they are run.

After you have entered/selected any other desired values in the Universal Template Details, save the Universal Template.

For each parameter in the script that you want to replace with a variable, create a Universal Template Field of an appropriate Field type. The Controller automatically assigns a variable (format: ops_<Variable Prefix>_<Field Name>) to each Field, using the variable prefix that you specified in Step 1, and - in the Details of all Universal Tasks based on this Universal Template - will place fields that match these Universal Template Fields (see Step 7).

Replace the appropriate parameters in the script with the system-assigned variables.

Update the Universal Template. Now that the Universal Template has one or more defined Fields, the Controller creates a Universal Task type for it and adds the Universal Task type to the Automation Center navigation pane. (You must refresh the Automation Center navigation pane in order to see the new Universal Task type.)

Create a Universal Task for that Universal Task type. The Universal Task Details will contain fields that match the Fields you created in the Universal Template (Step 4) for that Universal Task type.

Enter/change values in the Universal Task fields that match the Universal Template Fields, based on how you want their matching variables in the script to be resolved.

Run the task, which executes the script. The variables in the script are resolved to the values of their matching fields in the Universal Task.
