CompTIA Linux+ XK0-006 (V8) Practice Question

A script defines an array that may contain filenames with embedded spaces:

files=( "April Report 2025.pdf" "inventory.csv" "sales summary.txt" )

You must add a for loop that prints each filename on its own line without changing IFS or invoking external commands.
Which loop meets the requirement?

  • for f in ${files[@]}; do echo "$f"; done

  • for f in "${files[*]}"; do echo "$f"; done

  • IFS=$'\n'; for f in $(printf '%s\n' "${files[@]}"); do echo "$f"; done; unset IFS

  • for f in "${files[@]}"; do echo "$f"; done
