Bash Script to Fix Android Pictures and Videos Timestamp

/ Published in: Bash

After copying pictures and videos from my tablet to my PC I noticed that the original timestamp was overriden by the current date.

Fortunatelly the timestamp was still preserved in the files name.

Ex: IMG\_20150214\_202445.jpg or VID\_20140116\_091015.3gp

The script must be executed in the image's folder and voilÃ¡ the original timestamp will be restored.

Please make a backup before executing it!

I'll not bother myself with licensing. This piece of... software... may be used as you wish, and also at your own peril! I don't claim credit neither responsability over it.
