From your description, I haven't understood your requirement very well.
Though I suspect you might be looking at something like this:
dpkg --get-selections | sed -es'![ \t]\+.\+$!!' | tee
/var/tmp/installed-software | xargs apt-cache depends
It lists down all the dependencies/suggestions/conflicts of packages
on your system. If you just want to find out dependencies of few select
you want to remove, then put their names (one per line) in a file, (say
packages-to-remove) and run the following:
cat packages-to-remove | xargs apt-cache depends>/var/tmp/pkg-dpendencies
Thank you for the info.
I was thinking of removing certain packages in one go that were tried out
but were not found suitable in a new installation--so description of all
packages installed earlier was needed.
Thank you for your response. I guess I will have to go thru the apt
documentation fairly rigorously in order to get the description of each
package in one go.
That would be easy. Just list down such packages in a file, say
pkgs_to_remove.txt; one per line. Then run the following:
cat pkgs_to_remove.txt | xargs apt-get remove
It will remove all such packages in one go. Then there could be some
packages/libraries which were installed as part of some of the packages
you had just removed. To remove all those packages which are no longer
needed in the system, run the following:
From the man page of apt-get:
"autoremove is used to remove packages that were automatically installed
to satisfy dependencies for some package and that are no more needed."
