A systems administrator pressed Ctrl+Z after starting a program using the command line, and the shell prompt was presented. In order to go back to the program, which of the following commands can the administrator use?
The command the administrator can use to go back to the program is fg.
A. fg - This command brings a job to the foreground. In this case, the job is the program that was suspended using Ctrl+Z.
B. su - This command is used to switch to another user account.
C. bg - This command starts a suspended job in the background. It is not useful in this case because the administrator wants to bring the job to the foreground.
D. ed - This command starts the ed text editor. It is not useful in this case because the administrator wants to resume the program that was suspended.
Answer is A. Ctrl+Z suspended the process, and "fg" will bring it back into the foreground of the shell
