Re: Remove duplicate data from text file

[dragonchild]

1. Read the file into an array
2. Create a hash whose keys are the values in the array
3. Create an array from the keys of the hash
4. Print the array out to a file

The details are left as an exercise for the reader.

Don't go borrowing trouble. For programmers, this means Worry only about what you need to implement.

my $filename = ...;
local $/;
open IN, $filename;
$text = <IN>;
@words{split /\s+/, $text} = undef;
@words = keys %words;
