A Job script is another way to create a data integration process with Talend Studio. You can either:
write a script with the properties of each element of your process.
For more information, see How to create a Job script.
create a Job and display its script through the Jobscript tab to edit it if necessary.
You can create your Job script in any text editor and name your file with the .jobscript extension, or you can create it with the Integration perspective of Talend Studio. When you create it with the Job script API Editor of Talend Studio, the use of the auto-completion (Ctrl+Space) will ease the writing process of the script. Moreover, in the Studio, the code displays in color to be easily identified and you can create template in Talend Studio's preferences.
For more information on Job script preferences, see Job script preferences (JobScript).
To access Job scripts API Editor in the Studio, expand the Code node in the Repository of the Integration perspective.
