I'm thinking that I don't entirely trust what I 'exported' from my iPod and want to check it against the music data from my Windows What I want to compare is the entirety of the music data - though the file names and folder names are different, the data within them should be entirely unchanged. so I thought I could md5sum a directory tree but it only works on files. ;-( The data amount should be slightly over 3 Gb in both cases... [root@srv1 home]# du -s /home/music 18759612 /home/music [root@srv1 home]# du -s /home/samba/profiles/craig/My\ Documents/My\ Music/iTunes/iTunes\ Music 18776304 /home/samba/profiles/craig/My Documents/My Music/iTunes/iTunes Music Not the same ;-( probably indicates a problem Is there some absolute way to computer a checksum on a directory tree to compare the binary contents?
