Sorry, Wrongly understood the question.
Another approach is read the file2 content and split each line based on ':', and save in a hash, key will be 'enable_pad','c_pad','b_pad',etc and other string as value.
Read file1 and check each line exists in hash or not, if exists print it.
use strict;
use warnings;
open my $FILE2, "<", "file2.txt" or die "Cannot open file2 file: $!";
open my $FILE1, "<", "file1.txt" or die "Cannot open file1 file: $!";
my %hash;
while (my $eachline = <$FILE2>) {
chomp($eachline);
my($key,$value)=split(':',$eachline,2);
$hash{$key}=$value;
}
while (my $line = <$FILE>) {
chomp($line)
if(exists $hash{$line})
{
print $line:$hash{$line}
}
else{print "$line does not exist in file2"}
}
All is well. I learn by answering your questions...

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).
