PDF Batch Compressor

Functionality

This nifty utility compresses PDF files via Ghostscript in the folder where this script resides:

Create a sub-folder, ./compressed, and put the resultant compressed ones in it,
Compress files with any PDF extentions i.e., .pdf, .PDF, .pDf and so on,
Optional compression parameter to be supplied, namely, prepress, ebook (default) and screen - in the descending order of quality, and
Log output with the compressed file names and any error message in the sub-folder

N.B. Make sure to make this script excutable via chmod +x or chmod 755, after downloading!
