• download deskew tool (http://galfar.vevb.net/wp/2014/deskew-tool-version-1-10/) and copy from the Bin folder the binary corresponding to your platform to the parent directory of your images directory
• download/copy the bash script of this gist and put it in the parent directory of your images directory
• rename your images directory to input (or change that in the script ! :)
• make sure there is no output directory in your parent folder, because the script is going to overwrite it if it exists
• if on linux change rights of the script : chmod +x deskew_folder.sh
• run the script : ./deskew_folder.sh
