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.
