You've received excellent suggestions on how to split on whitespace to get the words out of lines.

The following is more than requested, but perhaps it will assist your scripting:

  • Always begin your scripts with use strict; use warnings;
  • Use lexically-scoped variables (my), including as file handles
  • Use the three-argument form of open
  • You can omit the parentheses when using chomp in your script (but not in all scripts)
  • The second chomp isn't necessary, since you'll be splitting on whitespace
  • You need to enclose your if(!exists $dict{$word}) ... within a for loop that iterates through the words in @words

Given the above, consider the following (it's been run through perltidy):

use strict; use warnings; my %dict; open my $infile, '<', 'words.txt' or die "can't open file $!"; while ( my $word = <$infile> ) { chomp $word; $dict{$word} = 1; } close $infile; while ( my $line = <> ) { my @words = split /\s+/, $line; for my $word (@words) { if ( !exists $dict{$word} ) { print "$word is mispelled\n"; } } }

I hope this is helpful.
