Ubuntu 9.04
Is there a way of producing a list of all applications and utilities
installed by me post-installation from the Ubuntu CD?
Hello, Gordon.
I've got a script that compares the packages installed on two different
machines, or between one machine and a list of packages. I create the
reference list immediately after installation using:
dpkg --get-selections >distribution_name.sel
Then later run my script e.g.:
dpkg-dsel localhost distribution_name.sel
Bye,
Tony.
