Hello all,

I need help with comparing files.

What I have is 30 files full of Mac Addresses.

I need to find the Mac Addresses that show up in all 30 files and output them to a new file.

The files are listed in an @all. Actually here is what I got so far.

$all=qx/ls \/export\/home\/*_01day
  @all1=split("\n",$all);
for(@all1){push(@all2,(split(' ',$_)));}
  @all3 = reverse(@all2);
@all4 = (@all3[0..29]);

[download]

So what is left is @all4 holds the 30 file names of the files I need to compare. Now im stuck. How do I go about opening and comparing these files to output the Mac addresses that show up in all 30 files to a new file.

Thanks.
