CompTIA Server+ SK0-005 Practice Question

A Linux administrator is writing a Bash script to archive several log directories each night. The directories are stored in an indexed array:

dirs=(/var/log/httpd /var/log/mysql /var/log/app)

The first attempt uses the loop below, but only one directory is processed:

for d in $dirs; do
  tar -czf "$d-$(date +%F).tgz" "$d"
done

Which array expansion should replace $dirs so that the loop iterates over every array element even if a path contains spaces?

  • Replace \(dirs with "\){dirs[*]}" in the for loop

  • Replace \(dirs with "\)" in the for loop

  • Keep the loop but quote $dirs as "$dirs"

  • Replace \(dirs with "\){dirs[@]}" in the for loop
