Conduct a search or test -f over a path with spaces
I am organizing my music library on a NAS server. I want to print a list of all the directories that are missing the cover art (at least one or more jpeg file). I have successfully created a file with each line containing the path to each occurance of one or more .mp3 files. That path is also expected to have one or more files ending in .jpg or .JPG.

My input file strings look like this:
Code:
/c/mp3/Bad Company/Rough Diamonds
/c/mp3/Bad Company/Burnin' Sky

Most of the directory paths have one or more spaces in the directory, preventing me from testing for files with the .jpg extension, plus I have no idea how to do a case-intensive test. I will probably just have to perform two tests. I get a file not found error if I quote the entire string like:
Code:
"/c/mp3/Bad Company/Rough Diamonds"

After much searching, I decided I need to convert each path to this format"
Code:
/c/mp3/"Bad Company"/"Rough Diamonds"

If I can just get the path in the above format, I should be able to test for a jpg file with:
Code:
[ -f /c/mp3/"Bad Company"/"Rough Diamonds"/*.jpg" ]

I have tried using the IFS="/" with the bash read and also awk with the IFS="/". Both these methods continue to use the space (and /) as an IFS and I end up with 6 fields in the case with the above path.

I am running an old version of linux, 2.6.17.14ReadyNAS, but I could do this over nfs with a modern kernel and tools. Any help would be greatly appreciated.

fatsort

fatsort(1)						      General Commands Manual							fatsort(1)

NAME

       FATSort - FAT filesystem sorting utility

SYNOPSIS

       fatsort [options] device

DESCRIPTION

       FATsort sorts directory structures of FAT filesystems.  Many MP3 hardware players don't sort files automatically but play them in the order
       they were transmitted to the device. FATSort can help here.

OPTIONS

       -c     This option causes FATSort to ignore the case of filenames (e.g. 'example.mp3' is equal to 'EXAMPLE.MP3').

       -f     Force sorting even if the device is mounted or if FATSort cannot determine if the device is mounted.

       -h     Shows some help information.

       -i     Prints some file system information of the specified device.

       -l     FATSort will not sort directory structures, but just print the current order.

       -o type
	      This options specifies how FATSort will sort files and directories.  type can be 'd' for directories  before  files  (which  is  the
	      default), 'f' for files before directories, or 'a' for no differentiation between files and directories.

       -n     Uses natural order to sort directory structures instead of  alphanumeric order.  For example, an alphanumeric order would be
		     file123.mp3
		     file21.mp3
		     file3.mp3
	      and the corresponding natural order would be
		     file3.mp3
		     file21.mp3
		     file123.mp3.

       -q     FATSort will work quietly without printing additional information messages.

       -r     Sorts the directories in reverse order (Z-A).

       -R     Sorts the directories in random order.

       -v     Shows version information only.

       The following options can be specified multiple times:

       -d directory
	      Sort directory only

       -D directory
	      Sort directory and all subdirectories

       -x directory
	      Don't sort directory

       -X directory
	      Don't sort directory and all subdirectories

       -I prefix
	      Ignore  filename	prefix	prefix	during sorting. For example, passing option -I "the " tells FATSort to sort 'The Beatles.mp3' like
	      'Beatles.mp3'.

EXAMPLES

       Sort FAT filesystem on an USB stick:
	      fatsort /dev/sda1

       Sort FAT filesystem in a file:
	      fatsort /home/user/fat16_fs.img

       Sort directory /dir1 and all subdirectories except /dir1/dirA:
	      fatsort /dev/sda1 -D /dir1 -x /dir1/dirA

       Ignore prefixes 'a ' and 'the ' during sorting:
	      fatsort /dev/sda1 -I "a " -I "the "
