Those two should not be related to it, only "cat" is opening the file not 
"bash".

I have difficulty in working out what that script does, but it doesn't seem to 
be opening the media file.  Also on my system the CD-ROM is /dev/hdc so a 
cd-rom script isn't expected to access anything related to /dev/hda.
