I have to analyse a lot of debian and rpm packages. I found command given above for rpm packages. This allows me to get details on content of package without downloading and directly through URI.

For eg. for rpm I can say

rpm -qp --queryformat "[%{FILENAMES} %{FILEMD5S} \n ] "http://somepath.com/examplePackage.rpm

This returns name of files and its checksum for each file in examplePackage.rpm.

Do we have a similar command for debian packages?

I have looked at dpkg-query, apt-file but all of them require *deb file to present locally.

I'd like to avoid downloading and extracting all *deb files.

Thanks for any pointers and help.

apt-cache specificly show and showpkg should meet most of your listed needs. The following code result is for a package that is not installed on my system but is available. apt-cache only reads from the APT's local package cache, and could be inaccurate if not recently updated.

  • Thanks!. I am aware of these but these commands do not solve the issue i am facing. As you said apt-cache is still dependent on the repos configured on the system which could be a problem if repos are not updated. – explorer Dec 23 '17 at 2:41
  • I could not figure out any better way. Choosing this as suitable answer. Thanks – explorer Jan 2 '18 at 1:14
