CompTIA Linux+ (XK0-005) — Question 92

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?

Answer options

• A. fg
• B. su
• C. bg
• D. ed

Correct answer: A

Explanation

The correct answer is 'fg', which brings the foreground process back to an active state. The 'su' command is used to switch users, 'bg' runs a job in the background, and 'ed' is a text editor, none of which will resume the suspended program.
