Code:
perl -ne '$"=qq{\n}; @mail = $_=~/saw:user name="(.*?)"/g and print "@mail\n"' dir1/inputfile{1,2,3} > output.result

What you are asking, now, changes the command radically.

I do not like how messy is becoming as a one-liner. Here's a proper Perl script.
Code:
#!/usr/bin/perl

use strict;
use warnings;

my %emails;
while(my $line = <>) {
    $emails{$_}++ for my @mail = $line =~ m/saw:user name="(.*?)"/g;
}

for my $email (sort keys %emails) {
    print "$email\n";
}

Save as extract_emails.pl
Run as
Code:
perl extract_emails.pl dir1/inputfile{1,2,3} > output.result

I did this way in one command and its working great ...

Code:
perl -ne '$"=qq{\n}; @mail = $_=~/saw:user name="(.*?)"/g and print "@mail\n"' demand360+alerts/* rate360+alerts/* | sort | uniq > /home/orabi/abc.txt

I guess you changed your mind. Smilie
My post #15 script will do what you asked previously. It would keep unique ones and it will sort it in Perl.

And, if you going to use sort | uniq (after explicitly saying you didn't want to do that in post #14 in this thread), you could at least replace those two commands in your pipeline with just sort -u.
