use mysql -e 'sql-command1;sql-command2;' syntax for shell script to dump infomation from a shell script.
for example
Code:
#!/bin/bash
file="/tmp/output.$$"
cat /proc/cpu >$file
mysql -u user -p password db-name -e "sql-command to dump data from $file"
/bin/rm -rf $file
Above is just an example now a working code but it should be used as starting point
you can call about script from a crontab
On a related note I recommend php for all sort of work for getting input from system to dumping data to generating reports. PHP can work from a shell and cron
