Save output PDF as original PDF File

[erodriguezseda]

First, this tool is awesome! I am starting to like Google Docs as it facilitates collaboration, but I hate that Google Docs doesn't translate the TOC when saving it as a PDF, and making the doc --> docx --> pdf messes with the format.

Anyway: I would like to automatically save the output file (with the TOC) as the original file. That is, I do not want to have two files (keeping the original without the TOC).

I tried:
pdftocio -o original.pdf original.pdf < toc
but I get an error: save to original must be incremental

Is there an easy way to automatically saved the TOC in the original file? Thanks!

I think this is a general "problem" with command-line utilities, they don't allow redirecting output to the same file used as input. Although it may seem obvious, the easiest thing to do is just do something like this:
pdftocio original.pdf < toc; mv original_out.pdf original.pdf
