After a recent bug report I've received [1] I thought to conduct a
survey on all packages available in Fedora to find conflicts between
binary names under /usr/bin but I don't know how exactly do that. Is
there a way to extract the list of all files installed under /usr/bin
from all packages?
I tried with 'dnf repoquery --disablerepo="updates" -l *.x86_64 | grep
"/usr/bin" &> filelist.txt' but it seems to only list files for
packages I've installed on my system.
My suspect is that this survey will result in many packages are using
the same very common binary names.
Ugly way: dnf whatprovides '/usr/bin/*' gives a list of packages that
needs some postprocessing. This reports 554 packages.
Next we do
for a in `cat /tmp/y` ; do dnf repoquery $a -l | grep /usr/bin; done
which results in 1210 files installed in /usr/bin/, of which 137 seem to
be 2,3 or 4-plicates.
The situation isn't quite bad, though, because packages are offered for
different archs and updates:
$ dnf whatprovides /usr/bin/gio

The only one I could see that is really provided by multiple packages is
/usr/bin/stap* : they seem to be provided by both systemtap-client and
systemtap-devel.
WHAT'S UP WITH THAT?
There's also /usr/bin/mailq, but it's legit because it uses 'alternatives':
