Who work longer hours with an Ubuntu or Debian system, of course, who knows to appreciate the package management. She is one of the arguments pro Linux, if not THE argument. Who does not have only one computer, but in addition to the desktop or a notebook, a netbook so often wants to have installed the same packages on all its computers.So you can seamlessly handle all the tasks on all computers. There have been around for some time tricks, how to create a package list on a system, and these grossed then on another computer.

How can you let

Addressed issue the command dpkg installed packages. With a bit of shell magic can be created from this list for a file that can then use on another computer to install the same packages. The bottom line is that the whole thing so …

# Package list on machine A create …$ Dpkg – get-selections | '! / Deinstall | purge | hold / {print $ 1}' awk>Packages.list# Install packages from the list on machine B.$ Xargs-a “packages.list” sudo apt-get installNow this approach works
