Check dependencies and generate download script before installing by dpkg
Solution 1
You can always try a dry run before the install,
dpkg --dry-run -i *.deb
Solution 2
You can get a list of the packages dependencies with:
find *deb -exec dpkg -f {} Depends \;
Solution 3
You can also try one of these
dpkg -I package
apt-cache rdepends package.deb
apt-cache showpkg package-name
this one is a combination of steps incase it's just a .deb file
ar -x <package-name>.deb
tar -xzf control.tar.gz
grep Depends control
or
apt-cache depends package-name
for example
apt-cache depends mplayer
but i think the last option is what might serve you best

Started using Linux and StackExchange since Ubuntu 12.04 LTS. Then Upgraded to 14.04 LTS. Now I am using Debian GNU/Linux on my Laptop and PureOS on old Desktop computer. I recommend visiting the Philosophy of GNU Project As I've replaced Ubuntu with Debian GNU/Linux, Now my question(s) are became off-topic on AskUbuntu. So, I continue to Unix & Linux. The second reason for my shifting to U & L is I found U & L more interesting than AU since AU is only Ubuntu specific whereas U & L is a broad concept and in my opinion U & L deserves generic questions. (I know why SE has AU & U & L both).

I used to install packages with
dpkg -i *.deb
command for off-line installation. Because all deb files are in one folder.I want to avoid dependency error and stop installing packages as broken.
Ultimately my aim is to check dependencies and generate download script (if all dependencies are not satisfied) for only those package which is missing in mentioned folder. so-that I can first download missing packages and Then confidently install package by
dpkg -i *.deb
apt-cache showpkg $(find -iname '*.deb' -exec dpkg --info '{}' \; | awk '/Package:/ {print $2}')
shows dependencies but long list and not helpful to check whethter it is satisfied (exist) in mentioned folder or not. Alsodpkg -I *.deb
errors following:dpkg-deb: 'cabextract_1.4-4_i386.deb' contains no control component 'chromium-codecs-ffmpeg-extra_34.0.1847.116-0ubuntu2_i386.deb' dpkg-deb: 'cabextract_1.4-4_i386.deb' contains no control component 'flashplugin-installer_11.2.202.350ubuntu1_i386.deb' .. .. so on for each deb
Hence, That commands are not useful for me.
Further Clarification:
- First check all deb dependencies in my folder.
- according to package already installed, check this deb's are able to installed without dependency error or not.
- if yes then execute
dpkg -i *.deb
- else list missing package which not fond installed or in mentioned folder
Thanks.

guntbert about 10 yearsDo I understand correctly that you expect to get a complete script from us? Why don't you use the results and write it yourself?
