Generate Installed Packages List

[ShareBuntu]

I'm trying to use "dpkg --get-selections > list.log" to generate a list of installed applications for when I do a clean install. Is there any way I could format this list to be on one line with only the package names and spaces in between the names?

I.e., how do I format list.log so I can simply copy/paste the contents into
"sudo aptitude install "? I don't want to use dselect.

You would just need to save your packages with:

dpkg --get-selections > myselections.txt

Then to restore the list just:

dpkg --set-selections < myselections.txt

Then do:

apt-get update

To refresh the selections then:

apt-get upgrade

Hope this helps.......

Thanks for the reply. I followed the first step, removed a package, added the selections in step two, updated and finally upgraded. However, it simply ignored the removed package - leaving me to assume it won't work. Any ideas?

I think the last command to issue after:

dpkg --set-selections < myselections.txt

would be:

dselect

But as I had read on your post, you don't like to use it.

I haven't used this myself but should work. Did you clean the repository after the removal:

sudo apt-get autoclean && sudo apt-get autoremove

This would clean any left over remnants of the removed package.

just a thought.....
