I put pages 1,35 , but I see only produces two pages. How can I indicate to print from page 1 to page 35 both included ?
again, you need to make sure you understand the PDFTK syntax - short answer is that the source files are aliased, ie
where file1 is referenced using the alias of 'A', file2 of 'B', and file3 of 'C' (note they MUST be upper case, but the script does this for you)
When inserting pages you use the alias's as follows
concatenate page 1 from file1 AND pages 1-5 from file2 AND all pages >= 10 from file3 in a new file
if you just want to concatenate the entire files leave the page number field blank and the files should be concatenated in the sort order
