Accidentally i removed files from /usr/local/bin in a custom OS based on Centos 6.4 release, then i tried to figure out which package used the files (python scripts):
/bin/rpm -qa | while read f;do /bin/rpm -ql $f | grep "usr/local/bin"&&echo -e" $f";done
/usr/local/bin
filesystem-2.4.30-3.el6.x86_64
So, no luck. Then installed a minimal centos in a Virtual Box but /usr/local/bin it was empty, how do i get some clue what files where there?
