cd {extracted_plugin_directory} rsync -av --dry-run --delete ../{extracted_plugin_directory}/ theHost:/volumes/www/theSite/wordpress/wp-content/plugins/{extracted_plugin_directory}/ |

gs -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -dPDFSETTINGS="/ebook" -sOutputFile=output.pdf input.pdf |
-dPDFSETTINGS={value} where {value} is one of: /screen – the lowest resolution and lowest file size, fine for viewing on a screen /ebook – mid-range resolution and file size /printer – high-quality setting used for printing PDFs /prepress – high-quality setting used for printing PDFs As always, YMMV…
