I'm using bash on Linux, and that doesn't like single quotes. in particular, 
the following command does NOT work:
gs -q -dSAFER -dDEVICEWIDTHPOINTS=595.28 -dDEVICEHEIGHTPOINTS=841.89 \
- -dCompatibilityLevel=1.4 -dNOPAUSE -dBATCH -r1200 -sDEVICE=pdfwrite \
- -sOutputFile='z\'x.pdf' -c .setpdfwrite -f 'z\'x.ps'

Hmm, doesn't the -sOutputFile=.... argument still need some thought about 
wrapping in quotes and escaping quotes?
Cheers,
