you can try this out.. this is not a very good script, just to give you an idea.

the first search sort all files based on time
it's hard to add "1" in the seconds since it will require time calculation.
i have used touch -t to change the timestamp of the file to current time instead.

the time format of touch -t is [[CC]YY]MMDDhhmm[.SS]
if you can calculate the time of the previous timestamp to add just 1 sec then your good to go.


for filename in `ls -lrt | grep \^- | awk '{print $9}'`
	timestamp=`date +"%Y%m%d%H%M.%S"`
	echo "The file name is $filename"
	timestamp_new=`../../tmp/ $filename`
	echo "the timestamp of $filename is $timestamp_new"

	if [ $timestamp_new = $timestamp_old ];then
		touch -t "$timestamp" $filename

Thanks a ton for the idea. changing the timestamp using touch command will definitely help me going forward. Once again thanks a lot for the useful reply.

i think i just found a solution for you.
i use date -r for epoch time, date -d to calculate time. i just added 1 second to modified epoch time of the file and convert the time.


for filename in `ls -lrt | grep \^- | awk '{print $9}'`
	echo "The file name is $filename"
	#timestamp_new=`../../tmp/ $filename`
	timestamp_new=`date +"%s" -r $filename`
	echo "the timestamp of $filename is $timestamp_new seconds pass 1970-01-01"

	if [ $timestamp_new = $timestamp_old ];then
		timestamp_new=`expr $timestamp_new + 1`
		timestamp=`date -d "1970-01-01 $timestamp seconds" +"%Y%m%d%H%M.%S"`
		touch -t "$timestamp" $filename
