Programming :: Exit My Script W/o Leaving An Orphan Process Running

It's called TextRipper and it creates indexable and editable text files from any image. Feel free to copy TextRipper; it's licenced under GPL. My troubles are with cracking passworded pdf's. (As you can see, I meant any when I said any image.)

I can't find a way for the user to cancel the decryption process by exiting the script without pdfcrack orphaning. Line 349 works the rest of the time; the concerned process is line 228. I believe it's a piping/subshell problem. At least that's how I've been going at it in vain.

I've made portability a priority and that the comments still require updating.

Code:

If the result is one output file, TextRipper will open it for you in OpenOffice Writer.

Otherwise all txt output files (editable and indexable) will be in the original file's directory." 0 0
