DSXchange

I want to transfer set of files from one directory to another what is the process to do so.

Welcome aboard.

Why use DataStage? You can use ordinary operating system utilities with a great deal less effort. Unless it is as a learning exercise, why would you spend so much money on a mv command? (Or cp if your UNIX does not permit mv across file systems.)

If this is part of some larger scheme, have DataStage execute the command, either from a job sequence or from a job.

As noted, how would you do this without DataStage? The answer is the same with it.

As replied by other members for this task you don't need DS, but if you are eager to do that the easiest option is to use BeforeSubroutine or AftersubRoutine with ExechSh option.
