Re: Compare 2 files and get data

[josera]

Hi:
Perhaps you wold have to use two while nested. In pseudocode, what i've think that you could use is:

while (<file1>){
   $line1=$_
   while(<file2>){
      $line2=$_
      foreach $field1 in $line1
         foreach $field2 in $line2
            if $field1 eq $field2{
               print $field1
            }
         }
      }
   }
}

It compare each field in file1 with each field in file2.
If what you want is that the two fields will be in the same line, then you could use, with only one while:

while (<file1> or <file2>){ #The longest of the two files
   $line1=read ($file1);
   $line2=read ($file2);
   foreach $field1 in $line1
      foreach $field2 in $line2
         if $field1 eq $field2{
            print $field1
         }
      }
   }
}

I hope that this pseudocode will help you
Yours sincerelly,
