LPIC-1 Exam 101 (Linux Administrator) — Question 40

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 '&', which is used in Unix and Linux systems to run a command in the background. The other options do not serve this purpose; '!' is used for history expansion, '+' represents the current directory in certain contexts, '%' refers to job control, and '#' is used for comments.
