Alternative to Adobe Reader in Ubuntu 14.04 for Anottation, Text Hightlighting etc...

I found this wonderful alternative to Adobe Reader for Ubuntu/Linux and it's called Okular which is a free software PDF reader.

What is it?

Here what there website says:

Okular is a universal document viewer based on KPDF for KDE 4. This means Okular works on multiple platforms, including but not limited to Linux, Windows, Mac OS X, *BSD, etc.

Okular combines the excellent functionalities of KPDF with the versatility of supporting different kind of documents, like PDF, Postscript, DjVu, CHM, XPS, ePub and others.

The document format handlers page has a chart describing in more detail the supported formats and the features supported in each of them.

 Okular gives you various options such as annotation, text highlighting, text extraction etc.

To install Okular in your Ubuntu:

 sudo apt-get update  
 sudo apt-get install okular
