This is a bash script based on Ghostscript that can be used to compress/resize a PDF.

This is a version of a script called resample.sh written by OSP.

Script

#! /bin/bash

pdffile=$1;
dpi=$2 

gs \
  -o "${pdffile%.pdf}-resized.pdf" \
  -sDEVICE=pdfwrite \
  -dDownsampleColorImages=true \
  -dDownsampleGrayImages=true \
  -dDownsampleMonoImages=true \
  -dColorImageResolution=$dpi \
  -dGrayImageResolution=$dpi \
  -dMonoImageResolution=$dpi \
  -dColorImageDownsampleThreshold=1.0 \
  -dGrayImageDownsampleThreshold=1.0 \
  -dMonoImageDownsampleThreshold=1.0 \
   "${pdffile}"
