If you want to find from which rpm package a file is installed, try following command:
repoquery -f <path/filename>
Example: if you want to find perl
[root@srv /]# whereis -b perl perl: /usr/bin/perl
[root@srv /]# repoquery -f /usr/bin/perl perl-4:5.8.8-42.el5.i386 perl-4:5.8.8-43.el5_11.i386 perl-4:5.8.8-42.el5.x86_64 perl-4:5.8.8-41.el5.i386 perl-4:5.8.8-43.el5_11.x86_64 perl-4:5.8.8-43.el5_11.x86_64
rpm -qf <file>
Example:
rpm -qf /usr/bin/implantisomd5 isomd5sum-1.0.10-5.el7.x86_64
