I've never been able figure out how to properly use printf. I've got the following line of code: 
printf %s18 %s18 %s18, ($ip_date_time[$i]{ip}, $ip_date_time[$i]{date}
+, $ip_date_time[$i]{time}, "\n");

which, in case you can't tell, is trying to print out three columns, one for each field, with a minimum width of 18. I just get some weird errors. The perldoc on sprintf and printf seems just about useless unless you are familiar with Cs sprintf function. Can someone point me to a tutorial on this function?
