After I asked this question I found that title and file name are pretty much different, so then I tried changing the pdf document's title to whatever I want to?.
I tried with Okular, but it doesn't let me change the title, I also tried GIMP but it just don't seem to have the option. I even tried verifying the document properties with Dolphin and it does not work either. How to change the title then?.
Solution:
After a deep web search using Google, I found a tool called
pdftk
(Title in the manual: pdftk - A handy tool for manipulating PDF). To install thepdftk
use the below line on the command line;then created a file named
updateTitle.txt
containing the following information:And saved it in the same location the PDF is, then I ran in a terminal (in the PDF’s location):
The PDF’s title is now "New Title".
