Rename image files using the EXIF date and time stamp
This little script is a simple tool to rename one or more files in a folder using the EXIF date and time stamp. Name collision is handled with a unique sequence number as needed.
#!/bin/bash#
# rename one or more images based on the date/time exif information
#
# the "exif" program must be instale for this to work. (sudo apt-get install exif)
#

help=0
count=0
err=0
