compress_pdf_script.sh

# Instructions: You should pass the name of file and the compress quality
# Usage example: ./compress_pdf_script.sh filename.pdf printer

#From the Ghostscript manual it can be seen that there are several qualities to choose from:

#screen – selects low-resolution output similar to the Acrobat Distiller “Screen Optimized” setting.
#ebook – selects medium-resolution output similar to the Acrobat Distiller “eBook” setting.
#printer – selects output similar to the Acrobat Distiller “Print Optimized” setting.
#prepress – selects output similar to Acrobat Distiller “Prepress Optimized” setting.
#default – selects output intended to be useful across a wide variety of uses, possibly at the expense of a larger output file.
