Hai friend,
What is meant by the job control and non job control
in unix.I think the foreground and background jobs are controlled by
the shell then it has the job control,but in non job control while we
run the job in background what it will do ? Please explain.

Job control refers to shell commands that allow you to deal with jobs as
a unit, and move them between foreground and background status on the
fly (e.g. typing Control-z to suspend a foreground job and then type
"bg" to move it to background).
In a shell without job control, you can run processes in the background,
but you can't then move them to the foreground. They just run
concurrently with the shell.
