Use this to re-arp all IPs currently on the interface. Change eth0 to eth1 or whatever as needed.

Use this when you are trying to delete 100s of thousands of files in a single directory, and can not do so using rm.
perl -e 'chdir "problem_dir" or die; opendir D, "."; while ($n = readdir D) { unlink $n }'

Modified version of the php script from https://www.zabbix.com/wiki/howto/monitor/db/mysql/extensive_mysql_monitoring_including_replication The regex wasn't matching anything for me. It now matches Server= and Hostname= correctly
