To merge (concatenate) pdfs:
|
|
|
|
$ pdftk inputs cat output newfile.pdf
|
|
|
|
|
|
To merge all pdfs:
|
|
|
|
$ pdftk *.pdf cat output newfile.pdf
|
|
|
|
|
|
To break a pdf into single page files:
|
|
|
|
$ pdftk input.pdf burst
|
|
|
|
|
|
To combine parts of two or more files, use handles:
|
|
|
|
$ pdftk A=firstfile.pdf B=secondfile.pdf cat A1-7 B1-5 A8 output newfile.pdf
|
|
|
|
========================================================================

|
|
To edit metadata is a multistep process:
|
|
|
|
1) Dump the pdf metadata:
|
|
|
|
$ pdftk input.pdf dump_data metadata.txt
|
|
|
|
2) Edit the metadata (Geany appears to work), adding:
|
|
|
|
InfoBegin
|
|
InfoKey: Author
|
|
InfoValue: Kenneth John Odle
|
|
InfoBegin
|
|
InfoKey: Title
|
|
InfoValue: Journal #42
|
|
|
|
(For "Title" enter whatever you want to see in the document's title bar as you read it.)
|
|
|
|
3) Update the metadata in the pdf file:
|
|
|
|
$ pdft input.pdf update_info metadata.txt output.pdf
|
|
|
|
Note that you must write to another file, as pdftk cannot overwrite the original file.
|
|
Thus, make the file you save the scan as different than what you want the final file to be named.

To shuffle pages (interleave double-sided originals):
|
|
|
|
Scan the front sides: 001a.pdf
|
|
This gives you pages 1 3 5 7 9
|
|
|
|
Scan the reverse sides: 001b.pdf
|
|
This gives you pages 10 8 6 4 2
|
|
|
|
$ pdftk A=001a.pdf B=001b.pdf shuffle A1-5 B5-1 output 001.pdf
|
|
|
|
001.pdf should now be in the order:
|
|
1 2 3 4 5 6 7 8 9 10
