arrays - Compare two text files in Perl -


i have several strings in 2 .txt file. both of them contain similar strings not arranged on same line number.

for example, file1.txt carmen edison molly jason damon gerard

file2.txt edison jason

i want save similar strings found in both text files (in case: edison jason) array.

without need use additional modules

#!/usr/bin/env perl use strict; use warnings;  @data1 = qw( carmen edison molly jason damon gerard ); @data2 = qw( edison jason ); @data3 = ();  foreach $d1 ( @data1 ) {     chomp $d1;      foreach $d2 ( @data2 )     {         chomp $d2;          if( $d1 eq $d2 )         {             print "match found : $d1, $d2 \n";             push @data3, $d1;         }     } }
