How I installed arabtex latex package on ubuntu 13.10

While compiling a latex project, the compiler complained it could not locate the package arabtex. This latex package is used to render Arabic script in pdf. A useful post "Easy installation/removal of a LaTeX package" suggested searching for the package using the command

apt-file -x search '/arabtex.sty$'

The command line prompted "The program 'apt-file' is currently not installed. You can install it by typing: sudo apt-get install apt-file"
Thus I installed apt-file first by

sudo apt-get install apt-file 

after installing the apt-file I again issued the command

 apt-file -x search '/arabtex.sty$' 

This time the terminal responded by

 texlive-lang-arabic: /usr/share/texlive/texmf-dist/tex/latex/arabtex/arabtex.sty

where the part before : i.e. texlive-lang-arabic indicates the name of the package required. Finally I issued the command

 sudo apt-get install texlive-lang-arabic 

to successfully install the package.
