Why don't you check the length of the string as well .. ie
if (length($word) == 5 $word =~ /^(un|in|non).+$/) {
## Do something

Hello everyone...
if you are looking for the regex only solution, then you may try this
$word =~ /^((un|in).{3}|non.{2})$/

The problem with eval in Perl 5 is that it catches any and all thrown exceptions
. I.e: by default, it doesn't do Object-Oriented exceptions like Java, Ruby,
Python

You should not use exceptions for normal code flow.
Read the DBI docs (perldoc DBI).
If a failed connection must be an exception, set RaiseError to true.
But if it isn't an exception, leave it false, and test $dbh-err (or the
I enabled RaiserError, then script die.

my %attr = (
PrintError = 0,
RaiseError = 1
);
my $dbh = DBI-connect($dsn, $user, $pass, \%attr); # or die Can't
connect to the DB: $DBI::errstr\n;
my $query = SHOW DATABASES;
my $sth = $dbh-prepare($query) or die Can't prepare SQL statement:

Use:
RaiseError = 0
instead so that your script will not raise an exception and die. Then
check $dbh-err.

You should use the matching operator on the right hand side of the
binding operator

Hi Guys,
I know there are modules for parsing tab delimited files, but I am trying to
develop a script as a learning exercise to learn the better, so any help would
be appreciated.
Let's say I have two columns and two rows:
Joe \t Doe
Jane \t Doe
So here is what I got:
#!usr/bin/perl
use
replace @array = split (/\t/, $_); with
@array = split;

I advise to not do that, because when you add more data - like
Joe Bob \t Briggs
@array will have three elements.
