And for the record, both littler and Rscript can do that without the need for double quotes, at least under Linux. E.g. both $ r -e 'postscript(file="", command="cat"); plot(0)' | head $ Rscript -e 'postscript(file="", command="cat"); plot(0)' | head provide the same output (of the beginning of the postscript output). Our r is as usual somewhat faster, not that this matters in this non-repeat context.
