Hi,
Can someone explain what's the difference between rpm, pkg and debian installer and what is the advantage of one above the other?
Thanks
Different operating systems / derivatives have different software package management systems.
rpm is the Red Hat Package manager which is widely spread. It's also used additionally on other Linux'es, AIX, etc.
pkg is afaik the SUN software package management tool.
For debian there are different. alien for installing RPMs, dpkg is down below all of them and on top are some like apt, aptitude and synaptic for example.
So there is not usually the question "which is better", since 1st there is the question, which OS do I use and so which is package manager is available.
