Hi Axel,
I was using the default shell (bash) and using .bashrc . After using
the '\' character (denoting space I guess) it works perfectly. I am
using oh-my-zsh alongwith it.

One question though what does ip stand for ?

ip  pidgin-whatsapp                                                 -
WhatsApp plugin for Pidgin
ip  urw                                                             -
UrW is a unique graphical roguelike RPG taking place in ancient
Finland during the late Iron Age.

As far as my understanding goes, p in debian stands for packages not installed.

Both these packages are not in Debian and don't think they will ever
come into debian.
