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\""

pdfconcat

PDFCONCAT(1)						      General Commands Manual						      PDFCONCAT(1)

NAME

       pdfconcat - program to concatenate several PDF files.

SYNOPSIS

       pdfconcat -o outfile.pdf input1.pdf [inputN.pdf ...]

DESCRIPTION

       This manual page documents briefly the pdfconcat command.

       pdfconcat  is  a small and fast command-line utility written in ANSI C that can concatenate (merge) several PDF files into a long PDF docu-
       ment. External libraries are not required, only ANSI C functions are used.  Several features of the output file are taken  from	the  first
       input  file  only. For example, outlines (also known as hierarchical bookmarks) in subsequent input files are ignored. pdfconcat compresses
       its input a little bit by removing whitespace and unused file parts.  This program has been tested on various huge PDFs downloaded from the
       Adobe  web  site,  plus	an  1200-pages	long mathematics manual typeset by LaTeX, emitted by pdflatex, dvipdfm and `gs -sDEVICE=pdfwrite',
       totalling 5981 pages in a single PDF file.

OPTIONS

       -o output.pdf
	      Place output in file output.pdf

SEE ALSO

       imgmerge(1), xpaint(1).
