What is the logrotate utility and how is it used?
What will be an ideal response?
OpenSUSE includes the logrotate utility that administrators can use to manage large numbers of log files; it offers automatic rotation, compression, removal, and mailing of log files. Typically, you don't use the logrotate command manually; instead, you run the utility as a daily cron job. This utility has its own configuration file in the /etc directory called logrotate.conf. The /etc/logrotate.conf file is well documented with comments that can be viewed with the less /etc/logrotate.conf command.
