Question

Which of the following is not a part of job control facilities?

(a) relate a job to the background

(b) bring it back to the foreground

(c) kill a job

(d) create a new job

This question was addressed to me in an interview for job.

The above asked question is from Process Management in chapter The Process of Unix

Answer 1

The correct option is (d) create a new job

Easy explanation: If we are using the C, Korn or Bash shell then we can use their job control facilities to manipulate jobs. Job control in these shells means that we can :

•    Relate a job to the background (bg)

•    bring it back to the foreground (fg)

•    kill a job (kill)

•    list the active jobs (jobs)

•    suspend a foreground job (ctrl-Z)
