Scan to PDF in Ubuntu, with Beagle Searchable Meta Data

This bash script lets you scan directly to a PDF and then search your scanned PDF's using beagle, not just by file name, but by the information (meta data), that you can save with your PDF.

I developed this script because I really want to have a paperless desk and I could not find an easy way to scan documents to PDF, (and find them again!).

A picture's worth a thousand words...

I have a "launcher" on my desktop called "scan", I just click it and....

Select colour or Grey (color or Gray) for the Americans!





Then press OK for each page of the PDF you want to make. (Cancel to finish)



Then give the PDF a file name... (jam recipe!)



Then some meta data so beagle can find it... jam, recipe, grannys, yum.



Thats all !

Now search for "grannys jam" in Beagle.....



And there it is !!



Here is the script, it was made pretty fast so......

Please feel free to mess about with it. And post improvements back here !

Programs you'll need..
zenity
ps2pdf
pdftk
scanimage

Copy the script into its own directory, chmod u+rxw. Thats all!.
