Firstly I am no pro at string manipulation but the working examples seems to
have no line feed characters, whereas the "dpkg --get-selections" creates a new
line for every package it prints.
In Unicode (linux)
LF: Line Feed, U+000A
I tried "dpkg --get-selections | grep -v deinstall$ | cut -d'\n' -f1" but
still had not luck though...
