   [root@serverX ~]# updatedb

2. Locate the configuration file logrotate.conf on serverX.

   [root@serverX ~]# locate logrotate.conf
   /etc/logrotate.conf
   /usr/share/man/man5/logrotate.conf.5.gz

3. Locate the configuration file networkmanager.conf, ignoring case, on serverX.

   [root@serverX ~]# locate -i networkmanager.conf
   /etc/NetworkManager/NetworkManager.conf
   /etc/dbus-1/system.d/org.freedesktop.NetworkManager.conf
   /usr/share/man/man5/NetworkManager.conf.5.gz
