Assistance with using quotes in shellscript programming

I am using a Linux command that shrinks a pdf using ghostscript from 100% zoom to 90% zoom. This command works properly from the Linux prompt:

Code:
 gs -dBATCH -dNOPAUSE -q -sDEVICE=pdfwrite -sOutputFile=sam1.pdf -c "<< /BeginPage{0.9 0.9 scale 30.6 39.6 translate}>> setpagedevice" -sPAPERSIZE=letter -dCompatibilityLevel="1.3" -dPDFSETTINGS="/printer" -dSubsetFonts=true -dEmbedAllFonts=true -f 2138WH.pdf

However, I'm trying to code this into a call from their ERP software (running on a SCO box) that needs to run the code on the Linux box. I'm struggling with the quotes, double quotes, etc. I've tried putting a \" in front of each quote with no luck. I think I need to use the eval command but I'm not sure. Any ideas on what needs to be done? Here is the latest change I've made:

Code:
eval ssh root@linux \""cd /submittals;gs -dBATCH -dNOPAUSE -q -sDEVICE=pdfwrite -sOutputFile=/submittals/012606-003e.pdf -c \""<</BeginPage{0.9 0.9 scale 30.6 39.6 translate}>> setpagedevice\"" -sPAPERSIZE=letter -dCompatibilityLevel=\""1.3\"" -dPDFSETTINGS=\""/printer\"" -dSubsetFonts=true -dEmbedAllFonts=true -f /submittals/012606-003b.pdf\""

NAME
ps2pdf - Convert PostScript to PDF using ghostscript ps2pdf12 - Convert PostScript to PDF 1.2 (Acrobat 3-and-later compatible) using ghostscript ps2pdf13 - Convert PostScript to PDF 1.3 (Acrobat 4-and-later compatible) using ghostscript SYNOPSIS
ps2pdf [options...] {input.[e]ps|-} [output.pdf|-] ps2pdf12 [options...] {input.[e]ps|-} [output.pdf|-] ps2pdf13 [options...] {input.[e]ps|-} [output.pdf|-] DESCRIPTION
The ps2pdf scripts are work-alikes for nearly all the functionality (but not the user interface) of Adobe's Acrobat(TM) Distiller(TM) prod- uct: they convert PostScript files to Portable Document Format (PDF) files. If the output filename is not specified, the output is placed is a file of the same name with a '.pdf' extension. Either the input filename or the output filename can be '-' to request reading from stdin or writing to stdout, respectively, when used as a filter. The three scripts differ as follows: - ps2pdf12 will always produce PDF 1.2 output (Acrobat 3-and-later compatible). - ps2pdf13 will always produce PDF 1.3 output (Acrobat 4-and-later compatible). - ps2pdf per se currently produces PDF 1.4 output. However, this may change in the future. If you care about the compatibility level of the output, use ps2pdf12 or ps2pdf13, or use the -dCompatibility=1.x switch in the command line. There are some limitations in ps2pdf's conversion. See the HTML documentation for more information. A large number of Adobe Distiller(TM) parameters which can be used to control the conversion are also documented there, including instructions for generating PDF/X and PDF/A documents. EXAMPLES
Converting a figure.ps to figure.pdf: ps2pdf figure.ps A conversion with more specifics: ps2pdf -dPDFSETTINGS=/prepress figure.ps proof.pdf Converting as part of a pipe: make_report.pl -t ps | ps2pdf -dCompatibility=1.3 - - | lpr SEE ALSO
