Hi all
Is there any easy way to get the description of all packages listed in a
file which contains the names of all such packages?
eg.
i used
sudo dpkg --get-selections >installed-software
to make a list of all installed software packages on my system
However I want to remove some of them in batch mode (from the command line)
instead of by using synaptic and deleting them one by one which is a
cumbersome process. So the description of such packages is needed in
another file containing a subset of names of packages likely to be removed.
How can this be done ?

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
/var/tmp/software-dpendencies
It lists down all the dependencies/suggestions/conflicts of packages installed
on your system. If you just want to find out dependencies of few select packages
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:
apt-get autoremove
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."

Xargs looks like a nice command. Thanks!
Very useful in running the same command over a list of lines in a text
file.

As a proper list etiquette...
Please trim your replies.

Yes, though the "cat" there is superfluous:
xargs apt-get remove < pkgs_to_remove.txt
