If you compare your output with the original, you'll notice that the
"pdftops -level3 -paper match"
part is missing from your command. Also not that you should replace $infile
and $outfile with the
actual filenames you use (or set them as shell variables).

Sample:

infile=myoriginalpdf ; outfile=myconverted.pdf; pdftops -level3 -paper match
"$infile" - | gsc -q -dSAFER -dBATCH -dNOPAUSE -sDEVICE=pdfwrite
-dPDFSETTINGS=/ebook -dAutoRotatePages=/None -dEmbedAllFonts=true
-dSubsetFonts=true -sOutputFile="$outfile" -dCompatibilityLevel=1.4 -c
.setpdfwrite -

Or, create a shellscript for it:
__________
#!/bin/sh
infile=$1
outfile=$2

pdftops -level3 -paper match "$infile" - | gsc -q -dSAFER -dBATCH -dNOPAUSE
-sDEVICE=pdfwrite -dPDFSETTINGS=/ebook -dAutoRotatePages=/None
-dEmbedAllFonts=true -dSubsetFonts=true -sOutputFile="$outfile"
-dCompatibilityLevel=1.4 -c .setpdfwrite -
__________


Put that in a file named "pdfcompress.sh" and run it with 
"sh pdfcompress myoriginal.pdf myconverted.pdf", or make it executable and
put it in your PATH.

HTH,
