How do I actually use the script?
I cd'd into the dir where the pdf is and executed your script and got this error message:

nigel at laptop:~/Hamaayan/Example$  "$infile" - | gsc -q -dSAFER -dBATCH -dNOPAUSE 
-sDEVICE=pdfwrite -dPDFSETTINGS=/ebook -dAutoRotatePages=/None -dEmbedAllFonts=true 
-dSubsetFonts=true -sOutputFile="$outfile" -dCompatibilityLevel=1.4 -c .setpdfwrite -
