A dpkg trick for fresh installations

After every fresh install, I used to download all the necessary packages that I had in the previous installation. This was definitely not easy, I could hardly remember half of them and it used to take a lot of time. But by using using dpkg we can do it in a few commands. Chk it out.

Before doing a fresh install, run this command to save a list of all package selections. This is a list of the packages that you had in your previous system.

[shredder12]$ sudo dpkg --get-selections > packages.list

Now, in the freshly installed system run this command to replicate all the packages that you had in ur previous installation.

[shredder12]$ sudo dpkg --set-selections < packages.list  &&  sudo apt-get dselect-upgrade
