pdftk isn't all that friendly towards scripting...I'll say that much.
I am going to work on this tomorrow...but to give you some feedback -
and I appreciate all of the thinking that you did on this..
$ cat I-A-files.txt | sed 's/ /\\ /g' | xargs cat | pdftk - output
I-A.pdf verbose
result, only last pdf in list was inserted in output file
$ cat I-A-files.txt |xargs -i pdftk "{}" cat output I-A.pdf verbose
-sh-3.2$ FILES=`cat file.txt | sed 's/ /\\ /g' |xargs`; pdftk $FILES cat
output I-a.pdf
cat: file.txt: No such file or directory
Error: No input files. Exiting.
Errors encountered. No output created.
Done. Input errors, so no output created.
$ mkdir temp; IFS=$'\n'; for file in `cat I-A-files.txt | sed
's/ /\ /g'`; do cp -v "$file" temp; done; cd temp; pdftk *.pdf cat
output ../I-a.pdf verbose ; unset IFS
This last one sort of worked...It's fixable/workable anyway.
Imagine publishing a book that is 400+ pages all separate Microsoft Word
documents (now being converted to OpenOffice, adding form elements and
then exporting into single page PDF documents...and I'm trying to script
the collection into a single PDF book. Nothing about this has been easy.
Thanks Charles
