You can start a job from step one or from an intermediate step. The tbuild -s command option allows you to specify the step from which the job should start, identifying it by either the step name, as specified in the job STEP syntax, or by the implicit step number, such as 1, 2, 3, and so on. Job execution begins at the specified job step, skipping the job steps that precede it in the script.
For information on using tbuild -s command, see Launching a Job.
