Naturally this returned a lot so we have to use common sense before
deleting something. That said, what about these:
/usr/bin/cc
/usr/bin/c++
/usr/bin/c89
/usr/bin/gcc
/usr/bin/gcov
/usr/bin/x86_64-pc-linux-gnu-c++
I think these are created by gcc-config, so don't belong to any package.
If you want to do this regularly, I'd suggest creating a list of
exceptions that you can exclude from find. You don't need to search
everywhere, /{,usr}/{,s}bin, /{,usr}/lib and /opt should be sufficient.
So if they were deleted things would still work? Just curious. This is
a recent install so I wasn't expecting it to find much, just files I
created basically. I just thought it odd that it found so many files
and that qfile/equery didn't know where they came from either.
That gcc one bugs me tho. It's in /usr/bin but doesn't belong to a
package. Just blows my mind, which ain't much right now. lol I got
to get better meds.
/usr/bin/gcc doesn't belong to any package. The gcc packages install
versioned files, like:
/usr/bin/gcc-4.5.2 ->
/usr/x86_64-pc-linux-gnu/gcc-bin/4.5.2/x86_64-pc-linux-gnu-gcc
When you run gcc-config to pick a compiler, it creates and/or updates
/usr/bin/gcc (and the others) to point to whatever version binaries you
selected.
If you deleted /usr/bin/cc, /usr/bin/gcc, etc. things would stop
compiling, but just running gcc-config will make them come back. If
/usr/bin/gcc is missing you will get an error about your GCC_SPECS being
wrong but that's because gcc-config tries to run `/usr/bin/gcc -v` to
check for problems. But the error is harmless -- just re-run gcc-config
again and you will see it finish with no problems.

Ahhhh. So it just links the gcc command to whatever version of gcc is
active. Kewl !! That makes sense.
I learned something today. Given my age, I may forget it tomorrow but
at least I know it today. lol
I do wish there was some way to find files that are not needed or used
tho. I would still go through the files and delete them manually but it
would be nice, especially on my old rig which has a pretty old install.
I bet /etc would have quite a few of them.
Thanks to you and Neil too.
