Yes, but this still highlights the final question as "sudo dnf download

How do I find where the source has been installed to when under dnfdragora
when I search for symlinks in either names or descriptions I only get a
reference to the binary package even though I have installed the source
package as shown by "dnf info symlinks" which shows both the binary and
source packages as being installed? Especially when I would have thought the
source would have been installed to a sub_folder of /usr/src, but there
isn't a symlinks sub_folder of /usr/src, it only has akmods, annobin, debug
and kernels sub_folders.
You shouldn't be using dnf to work with source rpm packages
(other than downloading them, but even that isn't really
required or optimal in most cases).  If `dnf install` for a
source can even be made to work, it's very, very far from
the intended use of dnf.

Rather, if you want to explore the corresponding source for
a Fedora package, use the fedpkg command.  For example, to
get the expanded source for the symlinks package:

    $ sudo dnf install fedpkg
    $ fedpkg clone -a symlinks
    $ cd symlinks
    $ fedpkg switch-branch f41
    $ fedpkg prep
    $ cd symlinks-1.7
    $ : ...
    $ : profit!

This downloads the source code, extracts it into the current
directory, and applies any patches (of which there are none
for this package, at this time).  That leaves you with a
symlinks-1.7 directory to explore.

If you don't want to use fedpkg, the next best thing, IMO,
would be `rpm -ivh symlinks-1.7-11.fc41.src.rpm` to
"install" it (as a normal user -- NOT as root).

That creates an ~/rpmbuild directory which contains SOURCES
& SPECS directories.  To expand the source, you'd run
`rpmbuild -bp --nodeps SPECS/symlinks.spec` (from the
~/rpmbuild directory).  That would put the expanded source
in ~/rpmbuild/BUILD/symlinks-1.7-build/symlinks-1.7.

Using fedpkg is much easier and I'd highly recommend that
instead of using rpmbuild, unless you have a strong desire
to first learn a lot about rpmbuild rather than just poking
at the symlinks source code. :)
I have used rpm to build the rpmbuild folder with the symlinks source in the sources sub_folder of that folder. I have run the rpmbuild command yet as what is in the sources sub_folder is enough for me to do the changes to the symlinks functionality that I want to do, which is only display the symlinks that exist and what they are if there is no option or the only option is -r, if any other options are specified then action those option without display the symlinks list as well.

regards,
Steve
