open FILE1,"out.prod" or die "Cannot open file $!";
@rec=<FILE1>;
%save=();
foreach $x (@rec) {
if ( $x =~ /2005/ ) {
chomp($first=$x);
$save{$first}=undef;
}
if ( $x =~ /time/ ) {
chomp($lat= $x);
$lat =~ s/.*?time=(\d+)\.\sms$/$1/;
if( $lat > "10" ) {
$save{$first}=$lat;
#print "Hash value is $save{$first}\n";
}
}
}
foreach $first (sort keys %save) {
if ($save{$first}) {
print "hash value is $save{$first} ms.\n";
}
}
If $x !~ /2005/ you have no $first.... thus $first is undef, meaning during the loop it prints out fine, but inside the hash, you're overwriting the same key everytime.
Also, why not just chomp $x at the start and get it over with there instead of chomping twice?

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).
