CompTIA Linux+ Powered by LPI (LX0-103) — Question 13

Which character, added to the end of a command, runs that command in the background as a child process of the current shell?

Answer options

• A. !
• B. +
• C. &
• D. %
• E. #

Correct answer: C

Explanation

The correct answer is C, '&', which is specifically used in shell commands to run processes in the background. The other options do not serve this purpose; '!' is for negation, '+' is not a command operator, '%' is often used for job specification, and '#' denotes comments in shell scripts.
