my ($file1,$file2,@cols) = @ARGV;
open( my ($fh2), $file2 ) or die $!;
#just the file2 operations
while ( my $row = <$fh2> ) {
chomp $row;
#print "$row\n";
next if $row =~ /^\s*$/;
$row =~ s/^\s+|\s+$//g;
my (@fields) = split( /\|/, $row );
# print "$fields[0]\n ";
for my $fieldnum (@cols) {
if ( exists $hash{ $fields[$fieldnum] } ) {
print $fh "$row\n";
next;
}
}
}
is this correct because i have to pass array variables in CL.
i was able to print but then how do i deal with arrays

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
