Greetings all,
Is there a way to query the database to list the packages
that depend on a given package?
I checked the man page, and I do not see such an option.
I see the option --requires, which is great - but would like the
converse of --requires, such as: --required_by
rpm -q --whatrequires pkgname will tell you what specifically requires
that pkg name - but not all the things that pkg provides.
For that, you would do:
% rpm --quiet -q --whatrequires $(rpm -q --provides pkgname) | sort -u
The uniquifying step being because rpm will print the list of consumers
for _each_ thing provided by pkgname.
but you'll need to do every file in the pkg, too.
b/c of file-requires.
One possibility is "abusing" --test with erasure, eg:
$ rpm -e --test <pkg>
To get just the depending package names something like this works:
$ rpm -e --test <pkg> 2>&1 | tail -n +2 |awk '{print $NF'}
- Panu -
Yes - that works nicely
rpm -e --test libguestfs 2>&1 | tail -n +2 |awk '{print $NF'}

But why is the name slighly mangled with the insertion of 1:
into the name? What's the usefulness of that?
