Identify file pattern, take count of pattern, then act

Guys -
Need your ideas on a section of code to finish something up. To make a long story short, I'm parsing a print output file that goes to pre-printed forms. I'm intercepting it, parsing it, formatting it, cutting it up into individual pages, grabbing the text I want in zones, building an .fdf (declares the zones), then populating (pdftk).

All of this is working fine.... In the end, I separate docs that have multiple pages (from those that don't) into a separate directory where I want to slam them together..in order. Single .pdf...for these multipages all with common "ID" name.

No problem getting the concatenation to work manually - I need your help with the code at the end of this bash script.

I've got a directory ($DIRECTORY) that has files that looks like this:
Code:
368363.pdf
368363-2.pdf
368363-3.pdf
368373.pdf
368373-2.pdf
368373-3.pdf
368389.pdf
368389-2.pdf

The beauty is, this directory will ONLY contain files that have other files matching it's first six characters as I move through line by line. And it WILL be in order with the first file being 'filname.pdf' and everything following...by line...being 'filename-2(++).pdf'.

What I want to do is simple...read the directory, take in a file, one at a time, store all it counterparts with the -'X'.pdf into a variable, then slam them all together with pdftk before I get to the next line (i.e - pdftk $ALL $pdform cat output $linem (m to indicate multipage since pdftk is a bitch about using same input and output names. I can put in a line at the end to move it all and cleanup).

Something like:

Code:
for f in $DIRECTORY; do
         FILE=$(echo ${f##*/})         #Cut out the path leaving filename.pdf
        CATEM=$(ls -1f|grep $FILE|sort|uniq|tr '\r\n' ' ') # Gives me each file, separated by space (rather than line) to input to pdftk as a variable...

I'm lost after this. I don't think my plan is going to work because the original file will contain EVERYTHING and won't be re-read as I 'do stuff'....

Need some fresh eyes/ideas on this...this script is HUGE and does a ton of processing and I think I'm just getting tired of looking at it! Lol...

Thanks, fellas.

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 ps2pdf14 - Convert PostScript to PDF 1.4 (Acrobat 5-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|-] ps2pdf14 [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 in a file of the same name with a '.pdf' extension in the current working directory. 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). - ps2pdf14 will always produce PDF 1.4 output (Acrobat 5-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, ps2pdf13 or ps2pdf14, 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. OPTIONS
The ps2pdf scripts use the same options as gs(1). 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
gs(1), ps2pdfwr(1), Ps2pdf.htm in the Ghostscript documentation BUGS
