I have a file entitled numbers.txt. It comprises the numbers listed above. Using perl, how would place leading zero in front of each line; so the length of each line will not be greater than 10. I tried using scalars in perl, but the value of the scalar only returns the numbers of elements in the file when the file is assigned to an array. 
The following is the need output:
0000020188     
0000018350     
0000004005     
0000127736
