in reply to separating two sententences

When you say "doesn't work" it tells us nothing. Try telling us what your expected output and actual output were.

For starters, I would add:

use strict; use warnings;
to your script make coding errors more obvious. and I would hazard a guess that you are not opening the file properly. checking the return code of the open would find that:
open IN,"<","file" or die "error opening file: $!";

      This tells us your ultimate goal, but does not describe what you expect the code of the OP to do and just what is going wrong. dreadpiratepeter was trying to get details of this kind.

      It seems that the OP code is a first attempt at reading the contents of a file and processing and printing the contents. This is a good first step to your final goal. As it stands, I can make a guess at what is happening. The regex  /("/w+/")/ has extraneous / (forward slash) characters in it that are interpreted as premature terminations of the regex (see muba's analysis below). Try something like this (untested):

      use warnings; use strict; my $filename = 'myfile'; open my $fh, '<', $filename or die "opening '$filename': $!"; while (<$fh>) { if (m{ ("\w+") }xms) { print "$1 \n"; } } close $fh;
      and you still have not told us what is not working. What happens when you run it? I spend all day with a QA department that thinks "doesn't work" is a legitimate bug report. I don't need it on the monks too ;)

        i am totally confused with regex here.it doesnt recognize the word after ; and between " " and another question is email address.some of them start with numbers and some with alphabet.oooooooooh!!
