Copy files WITH verification process for .sh script

weklica asked
Last Modified: 2012-05-10
I have a directory with many sub-directories.  Each sub-directory contains thousands of files (for a total of 3.5 million).  I want to move each file to a single destination directory (remove from sub-directories).  However, a process runs on files received so I don't want to dump millions of files at once.  I would prefer that it move files from the source to the destination in a bit of a controlled fashion as follows:

Instead of just blasting them through and waiting for 10 seconds to loop as indicated in the script I pasted below, is it possible to have a file move and not have the next file move until the last one is gone from the new destination folder?  The destination folder is a cache folder.  The files there will not remain very long.  Once processed, they are moved again.  So, I would like to move each file from /Users/Shared/Source to /Users/usrnm/Documents/Test as indicated in the script below, but I don't want it to move each next file until it verifies that the file it just moved into /Users/usrnm/Documents/Test is no longer present.  So, sort of a check and balance control.  move all files from A to B, but don't proceed until each last file disappears from B.

Thanks in advance!
while :
cd "/Users/Shared/SOURCE"
sudo mv * /Users/usrnm/Documents/Test
 sleep 10
