Using Zypper or the RPM command line, is it possible to list all packages (and/or all locally-installed packages) that specify SomePackage as a dependency?
There is an option in the yast software manage search
Here you go…
https://en.opensuse.org/Libzypp/Dependencies
$ zypper help search
$ echo "An example"
$ zypper se --requires-pkg libzypp
The --requires-pkg option is just what I needed, thank you!
The man pages are a good reference…
From ‘man zypper’…
–requires-pkg
Search for all packages that require any of the provides of the package(s) matched by the input parameters.
