Like command files, job files free you from having to perform the same sequence of tasks over and over again.
You might think of a running a job as a little like delegating your work to someone else who goes off into another room and works quietly, without supervision, until the work is finished. If you are confident about the work that this other person will do--about the job that you design--the savings in time and effort on your part can be considerable.
At the same time, jobs offer advantages--and disadvantages--over using a command file.
The first advantage of using jobs is that they can save you time when you need to
perform a series of tasks that is complex or time-consuming.
The second advantage of using jobs is that you can instruct the computer to execute
the job at a later time, perhaps after you have gone home for the day.
The chief disadvantage of using jobs is that it takes a little more time and effort
to create the job.
When an error--or something unexpected--occurs in a job, it can take a little time to determine exactly why something went amiss.
