#! /bin/bash
# Script:    ImageNames.sh
# Purpose:   Transfer image and video files from any camera and rename them according to the date taken.

#
# Workflow:
#   The first time, put this script in an empty directory and start it from there.
#   Set the camera to [Usb Mass Storage] mode and connect it. Change the line below accordingly.
#   Run the present script from a bash window or from a bat file containing 
#     SET PATH="/usr/local/bin:/usr/bin:/bin"
#     c:\cygwin\bin\bash ImageNames.sh
#     PAUSE
#   It will move the files from the camera to the present directory 
#   and then move and rename them to YYYYMMDD\YYYYMMDD-HHMMSS.ext
#   You can then rename the directories and files to something more meaningful
#   For instance I use YYYYMMDD_PlaceOrEventName\YYYYMMDD-HHMMSS_SomeKeywords.ext
#   Next time you run it, new files are added.
#
# Make sure you have a backup of the whole directory the first few times you run this
# I take no responsability if you wipe out 2000 images or your camera catches fire.
#
# You need cygwin to run this on Windows: http://www.cygwin.com/
 
 
# This is the directory where the camera files are found 
# when you connect the USB cable OR use a card reader (faster)
# MAKE SURE THIS IS CORRECT.
## This is specific to a given camera
#PathCamera=$( cygpath "E:\DCIM\100RICOH" )
# This looks for any kind of card reader or USB-mounted camera drive
PathCamera=/media/dcam/*
 
 
# You shouldn't have anything to change below here
