Using constantly changing varibles in perl. I have a file that uses tail to count every new line per second in a file. i am trying to change it so the varible $line_ps will not make a newline when printing. right now what im doing is: 
system 'clear';
print "Lines P/s: $line_ps";
print "Average Lp/s: $average";
print "Total lines: $t-lines";

Im trying to make it so i do not need to clear it anymore. Where i can just have that variable printed change every time the variable changes.
