Useful Find Command

TIP: To find out where Reporter is installed on LINUX without using an RPM command (because it was not installed by RPMS):
       Navigate to the root of the file system and execute the following commands:
       Enter [[email protected] /]# find  -type d -name reporter
       NOTE: Substituting -name for -iname in the above command makes the Find Command insensitive to case.
