Is it possible to execute one script which reads through a file containing a list of packages/applications, tests if each entry is already installed and if not, proceed to install?
I'm trying to find an approach which I can use in installing applications on a number of virgin servers autonomously.
dpkg --get-selections > selectionson one computer thendpkg --set-selections < selectionson the other servers. Also, check unix.stackexchange.com/questions/7364/… unix.stackexchange.com/questions/79125/… unix.stackexchange.com/questions/8272/… etc.)
