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.

Hi shirish,

The backslash avoids that zsh tries to lookup the home directory of
the user "o". Think of e.g. "cd ~o".

I've no experience with omz, but it seems to change quite a bunch of
zsh default settings...

The first letter is the current state (i = installed), the second
letter is planned state in aptitude (and only aptitude) and the p
means "purged".

Means that if you run aptitude to install or upgrade packages, it
would remove these two packages -- maybe because they have been purged
once with aptitude but then installed with apt-get or dpkg again. Or
because they have been schedule interactively for purging but the
scheduled actions have never been executed with aptitude, e.g. by
exiting aptitude with "q" after having made changes to the wanted
package states interactively or with --schedule-only.

That should not make a difference here.

		Kind regards, Axel
