Batch renaming of files with a modified timestamp on Linux

Question

As part of a personal project I have generated a large number of frames.

I want to rename around 6000 png image files in terminal so that within the name they have the time that the frame represents.

eg

Frame_0001.png to Frame_DDMMYY_HHMMSS.png

Frame_0001.png to Frame_201114_134612.png Frame_0002.png to Frame_201114_134613.png and so on...

The first frame starts at 13:46:12 on the 20th November 2014. I want the rest of the images to be renamed sequentially so that they are all named after the date and time they represent.

Any help is greatly appreciated.

Answer 1

用perl的（p）重命名：

rename -n "s/\d+/$(date +%d%m%Y_%H%M%S)/" Frame_0001.png

Answer 2

The way I understand your description is that each frame represents one second of a contiguous sequence.

start='13:46:12 20 November 2014'
for i in `ls Frame_????.png|sed 's/Frame_\(....\).png/\1/'`
do  time=`date -d "$start - 1 second + $i seconds" +%d%m%y_%H%M%S`
    mv Frame_$i.png Frame_$time.png
done
