Finding which package provided a file on a CentOS Linux system

If you wish to know which package provided a file on a CentOS Linux system, you can use the RPM command

rpm
-qf

followed by the location and name of the file. E.g., to find which package provided the geopiplookup utility, which allows one to determine which country a particular IP address is associated with, I could determine the file's location and then use the RPM query.

[root@localhost ~]# which /usr/bin/geoiplookup
/usr/bin/geoiplookup
[root@localhost ~]# rpm -qf /usr/bin/geoiplookup
GeoIP-1.5.0-13.el7.x86_64
[root@localhost ~]#

If you want information on the package, you can use the

rpm -qi
packagename

command. E.g.:

[root@localhost ~]# rpm -qi GeoIP

Summary     : Library for country/city/organization to IP address or hostname mapping
Description :
GeoIP is a C library that enables the user to find the country that any IP
address or hostname originates from. It uses a file based database that is
accurate as of June 2007 and can optionally be updated on a weekly
basis by installing the GeoIP-update package. This database simply contains IP
blocks as keys, and countries as values. This database should be more complete
and accurate than using reverse DNS lookups.

This package includes GeoLite data created by MaxMind, available from
http://www.maxmind.com/

Alternatively, you can use yum to determine which package contains a file and which repository provides the package. E.g.:

[root@localhost ~]# yum whatprovides /usr/bin/geoiplookup
