Read barcodes in a PDF and save files with a named based on barcode

We need a script that can run on Linux/ubuntu/redhat that can read a single PDF ( in a folder) and then pull that apart and saved lots of PDF's based on the barcode that it finds. An example of the flow 1) read [login to view URL] (from a input folder) Page 1 must be saved as [login to view URL] Page 2 has the same Barcode so merged to the end of [login to view URL] page 3 must be saved as [login to view URL] Page 4 has the same Barcode so merged to the end of [login to view URL] page 5 to 7 have no bar code so much be merged to the last pdf that was created - in this case [login to view URL] Page 8, 9 merged to the end [login to view URL] Page 10 must be saved as [login to view URL] Page 11 has the same Barcode so merged to the end of [login to view URL] Page 12 must be saved as [login to view URL] Page 13 has the same Barcode so merged to the end of [login to view URL] Page 14 must be saved as [login to view URL] Page 15 has the same Barcode so merged to the end of [login to view URL] once completed reading the [login to view URL] the following 2 options may need to happen Human required 1) A simple webpage will need to list all the PDF that have been processed 2) A select all for approval - eg So a human can confrim that it has the correct number of pdfs and not linked some to others as it has been unable to read the barcode. 3) once human has ok'd the pdf's then save them to a folder ( should be configureable) Human NOT required 1) A simple webpage will need to list all the PDF that have been processed 2) the pdf's then save them to a folder ( should be configureable)
