I have 4 files in my /lib/ directory (Raspbian Buster)... 3 of them seem to be symlinks
1. cpp
2. ld-linux.so.3
3. ld-linux-armhf.so.3
and one file that, while trying to exit a black video played via omxplayer, I accidentally seemed to have renamed:
4. klibc-fAGGTaZfOmYXUytsXgfSuL5MT48.so
I have many directories in /lib/ as well that seem unharmed.
I've tried many different things at this point, could someone please look in their /lib/ folder and tell me what the filename is supposed to be?

Thanks,
E
