Hi all, If i have a file with one column of values then a second with three columns, i need to check that the value in column one exits in column one of file two. If this is true then print the line line of file 2. 
file1
1
2
3

file 2
2  43 56 
6  34 56
8  24 48

so 2  43 56  printed

i though of reading both files in to an array then using something like 
if ($file1[0] == $file2[0]) {print @file2}
