<p>Although there are several solutions for your task, consider the following:</p>
<c>
use warnings;
use strict;
my $names = 'names.txt';
my ( $found, $name );
print 'Enter a name: ';
chomp( my $input = <STDIN> );
open my $fh, '<', $names or die "Cannot open $names: $!\n";
while ( $name = <$fh> ) {
chomp $name;
if ( $input eq $name ) {
$found++;
last;
}
}
close $fh;
if ($found) {
print qq{The name "$input" was found.\n};
}
else {
print qq{The name "$input" was not found.\n};
}
</c>
<p>Note that:</p>
<ul>
<li>The name to search for is requested first.</li>
<li><c>chomp</c> is used to remove the trailing input record separator (usually <c>\n</c>), from both the entered name and the names from the file.</li>
<li>The names' file is read once; no hash or array is necessary to 'hold' the names (Why process the list twice?). A flag's set and the <c>while</c> loop is immediately exited if the name is found.</li>
<li>Appropriate responses are given depending upon the value of <c>$found</c>.</li>
</ul>
<p>Hope this helps!</p>
