[SOLVED] HOWTO obtain stats related to overall installation

[rshetye]

e.g. doing an apt-get install or apt-get remove yields,

(Reading database ... 104905 files and directories currently installed.)

How do I get this information in bold without doing an install or a remove?

thanks.

--- edit ---
wrote a script to do this

dpkg-stats.rb

#!/usr/bin/env ruby

# $DEBUG=true
# $VERBOSE=true

1. Output must list the files and directories installed by apt, and the files/dirs missing (e.g. due to localepurge)
2. Get the info for all installed packages from the dpkg db
3. Add each entry into a hash array for dirs, or a hash array for files, if the entry does not already exist in the corresponding array
4. Multiple references to dirs are ok
5. Multiple references to files are not ok, should be flagged
6. If the listed file/dir does not exist on disk, not ok, should be flagged
7. Print out all the details!!
8. ???
9. Profit!

ps: for testing purposes, use Dir.glob for q*.list rather than *.list, its easier to deal with a much shorter list

sudo synaptic

to see all packages installed.

You can get a list of all installed packages with the command:

dkpg --list > pack.txt
Now using Nautilus go to your home directory and double click on the resulting file pack.txt to view the package list.

thanks guys, but I am specifically looking for the command that will provide the number of installed files and directories, without any install/remove operation.
