    Done bash while loops for years but im used to seeing the following to read a file line by line
    while read line
  #code
done < file

    But have come across this
    while read section file_path; do
    # code...
 done < file

    What is this doing?

    section will be the first token from the line, file_path will be the rest

    input is probably something like

    A /mnt/cheezburger
    B /mnt/whatever
    C /mnt/lalalal
