Simple perl script

I need perl script that will do following: 1. Get database name and password from system variables (for example $DBNAME and $DBPASS) 2. Select from that database from specific table list of parameters to array (for example select name from users) 3. Then for each element in array run system command using value from array as parameters of that command. e.g. test -u <parameter from database> 4. Output from that command should be redirected to file with name: <parameter value>.<timestamp> 5. Also there should be csv report that will contain each filename generated, data and time of running this command and output file name with full patch Please use intuitional variables - because probably I will have to change for example variable name or db table etc. Regards, M
