Oops!

I should have made it clear!

Code:
#! /opt/third-party/bin/perl

open(FILE, "<", secondfile) || die ("Unable to open secondfile. <$!>\n");

while( <FILE> ) {
  chomp;
  @split_arr = split(/ /, $_);
  my $dump;
  for( my $i = 1; $i < $#split_arr + 1; $i++ ) {
    $dump .= $split_arr[$i];
  }
  $fileHash{$split_arr[0]} = $dump;
}

close(FILE);

open(FILE, "<", firstfile) || die ("Unable to open firstfile. <$!>\n");

while( <FILE> ) {
  chomp;
  @split_arr = split(/ /, $_);
  my $dump;
  for( my $i = 1; $i < $#split_arr + 1; $i++ ) {
    $dump .= $split_arr[$i];
  }
  print "$split_arr[0] ";
  foreach my $key ( keys %fileHash ) {
    if( $fileHash{$key} =~ m/$dump/ ) {
      print "$key ";
    }
  }
  print "\n";
}

close(FILE);

exit 0

matrixmadhan -
I find some minor problem on the code. It should search for the exact file pattern.

In my example below:

record1
mary MI_AP
anne MI_RC

record2
role1 MI_AP_REC
role2 MI_AP MI_RC

output of the current code:
mary role1 role2
anne role2

Is it possible that it should only search for exact word so the output will be (below) ..?

mary role2
anne role2

if it has to match exact string change the above to

Code:
 if( $fileHash{$key} =~ $dump ) {

Try that! Smilie

run the below as such and let us know the results

I have modified the code

Code:
#! /opt/third-party/bin/perl

open(FILE, "<", secondfile) || die ("Unable to open secondfile. <$!>\n");

while( <FILE> ) {
  chomp;
  @split_arr = split(/ /, $_);
  my $dump;
  for( my $i = 1; $i <= $#split_arr; $i++ ) {
    $dump .= ( $split_arr[$i] . ":");
  }
  $dump =~ s/:$//;
  $fileHash{$split_arr[0]} = $dump;
}

close(FILE);

open(FILE, "<", firstfile) || die ("Unable to open firstfile. <$!>\n");

while( <FILE> ) {
  chomp;
  @split_arr = split(/ /, $_);
  my $dump;
  for( my $i = 1; $i < $#split_arr + 1; $i++ ) {
    $dump .= $split_arr[$i];
  }
  print "$split_arr[0] ";
  foreach my $key ( keys %fileHash ) {
    @diff_arr = split(/:/, $fileHash{$key});
    for( my $i = 0; $i <= $#diff_arr; $i++ ) {
      if( $dump =~ $diff_arr[$i] ) {
        print "$key ";
      }
    }
  }
  print "\n";
}

close(FILE);

exit 0
