Actually lets make this more clear, let's say I have an text file like this : 
w1
w2
w3
[t4 w4]
w5
w6

[download]
and I want to process it to have something like this in output : 
w1
w2
w3
w4 t4
w5
w6

[download]
each w is a token and t is a lable for some tokens. I've tried this but it dosnt work and I get the same output. 
use strict;
  my $file = $ARGV[0];
  open IN, $file or die "Can't open";
  my @file =<IN>;
  close IN;
m/\[(\S+)\s(\S+)\]/ ? print qq[$2 $1\n] :print qq[$_] for @file;

while my file is a text with my data as below. 
w1
w2
w3
[t4 w4]
w5
w6
