The bpxtrace command provides details on job activity. It enables you to start a job with tracing activated, or enables you to dynamically activate tracing for a job that is already running. For example, to activate job tracing for the echo command, enter:

 bpxtrace -c -f format "echo hello"

This command produces tracing output (to stdout) and formats the output in one line per trace record format. For more information about the bpxtrace command, see z/OS UNIX System Services Command Reference.
