Odd behavior with mv - "Directory not empty'

[Masterkeedu]

I have a bash script, listed in crontab that archives my junk drawer.

THe problem is that for about half a dozen files it gave trying to mv saying

mv: cannot move `/home/eddie/junk/logs' to `/home/eddie/junk/archive/2009_Feb/logs': Directory not empty

If I copy the exact paths printed above (which are correct) and manually enter

mv /home/eddie/junk/logs /home/eddie/junk/archive/2009_Feb/logs

and it does as you would expect no trouble.

So why is it different in my script? The obvious different is the IFS, but I am doing this to allow files with spaces, and it works fine if the destination directory doesn't exist.

#!/bin/bash
 

#change IFS so we can handle files with spaces
RETURNIFS=$IFS
#IN case we blow, trap for exit so we can restore IFS
trap `IFS=$RETURNIFS` 0 1 2 6 9

# copy in place, trap set, change IFS
IFS=$(echo -en "\v")


OLDFILES=$ACTIVE_DIR/*
set -- $OLDFILES



# run thoughm, compare time and move out or in.
for ITEM in $OLDFILES 
do	

		mv $ITEM $DPATH
		if [ $? -ne 0 ]
		then	
			echo "Error while moving last file" | tee -a $LOGFILE
			exit 2
		else
			printf "\tSuccess\n" | tee -a $LOGFILE
		fi
	fi
done 

IFS=$RETURNIFS

If you are 100% sure that the folder you want to move to doesn't exist,
then add a rm -fr before the mv command?
