#! /bin/bash
#07/06/18 A BASH script to collect EXIF metadata 
#07/06/18 create metadata directory, create text file output for each file, append basename, place output in metadata directory
#07/06/18 create script.log to verify processing of files and place in metadata directory 
#07/06/18 Author: Sandy Lynn Ortiz - Stanford University Libraries - Born Digital Forensics Lab
#08/21/18 TO RUN: Place the script in the working directory. The script will search sub-dir's.  Open a terminal window (command prompt) and navigate to the working directory i.e. cd /path/to/directory. Type ./SAA.sh and hit enter.  The script will take a few min to run (start with a small set of testing files), depending on the number of files. It will prompt you when it completes. Try different commands in place of EXIFTOOL per your need.  **This is a functioning prototype only - *Not* intended for production**
