# Since filenames have spaces, first need to run these two statements to prevent delimiter errors:

# Back up default IFS to be restored later
SAVEIFS=$IFS

# Set IFS variable to account for spaces in filenames
IFS=$(echo -en "\n\b")

# Main Loop - For each jpg, use perl stat() to extract the file's create-time attribute and if within bounds, move to new folder

# For each element f in "*.jpg"
for f in *.jpg
do
	
	# Make $f available in perl shell ( interface between bash <-> perl )
	export f;

	# Use the perl stat() function to obtain file created-time attribute:
	  # 1. Use wrapper $ENV{f} so $f it can be resolved in Perl, then use it in the stat() function:  stat ( $ENV{f} );
	  # 2. Stat() returns an array of file attribute values which is stored in @temp:  @temp = stat (...);
	  # 3. Output the 10th element of array temp:  print @temp[10];
	  # 4. Output from perl script is saved as variable ctime:  ctime=$(...)

	ctime=$( perl -e '@temp = stat ( $ENV{f} ); print @temp[10];' );

	# If $ctime is > May 30th and < Jun 2nd
	if [ $ctime -gt 1306713600 ] && [ $ctime -lt 1306972800 ]
	then
	
		# Move the file named $f to folder
		mv "$f" newfolder
	fi

# Restore IFS variable back to default
