Querying for dpkg package summaries (Ubuntu)
Querying for the summary of a dpkg package is useful when you do not know which product the package belongs to. For instance, it might be useful if you have moved or copied packages from the XL C/C++ DVD or E-Image layout. The dpkg package summary includes a short description of the queried dpkg file.
To query for the summary of a dpkg package that is not installed, issue this command:
dpkg -f pkg_file_namewhere pkg_file_name is the full file name of the dpkg package that you want to query for a summary.
For instance, to query for the summary of the xlc.13.1.2_13.1.2.0-$B_ppc64el.deb file that has not yet been installed, issue the following command:
dpkg -f xlc.13.1.2_13.1.2.0-$B_ppc64el.debThe resulting output depends on the specific file queried, but the following is a typical example:
Package: xlc.13.1.2
Version: 13.1.2.0-$B
Section: Development/Tools/Compilers
Priority: extra
Architecture: ppc64el
