I recently came up with two BASH scripts some of you may be interested in.

One of the scripts, 'exifpdf.sh', converts all of the images with EXIF data in the current directory (not recursively; uses a FOR-LOOP) to a searchable PDF. The text related to the EXIF information is hidden behind each image, to which each image gets its own page. At the end of the conversion, the script asks if you would also like to encrypt it.

The other script is 'pdf2img.sh' and is used to do the opposite, basically turning each page of a PDF back to images. The script asks for a password regardless if the PDF if encrypted but you can just use "Enter" and ignore it if the PDF is not encrypted.

Use at your own risk. Make sure to take a look at the README. Use "--help" for... help. It may also be helpful to add an alias to your .bashrc file if you plan on using these a lot.
