Be aware that $0 doesn't always contains the full path of your script
Example: myhost:> ./myscript.pl
Running a script with above command line, $0 will be ./myscript.pl
So File::Basename will no longer help.
So I suggest you using FindBin module instead:
C:\>perldoc FindBin
NAME
FindBin - Locate directory of original perl script
SYNOPSIS
use FindBin;
use lib "$FindBin::Bin/../lib";
or
use FindBin qw($Bin);
use lib "$Bin/../lib";
DESCRIPTION
Locates the full path to the script bin directory to allow the use of
paths relative to the bin directory.
This allows a user to setup a directory tree for some software with
directories <root>/bin and <root>/lib and then the above example will
allow the use of modules in the lib directory without knowing where the
software tree is installed.
If perl is invoked using the -e option or the perl script is read from
"STDIN" then FindBin sets both "$Bin" and "$RealBin" to the current
directory.
EXPORTABLE VARIABLES
$Bin - path to bin directory from where script was invoked
$Script - basename of script from which perl was invoked
$RealBin - $Bin with all links resolved
$RealScript - $Script with all links resolved
KNOWN BUGS
if perl is invoked as
perl filename
and *filename* does not have executable rights and a program called
*filename* exists in the users "$ENV{PATH}" which satisfies both -x and
-T then FindBin assumes that it was invoked via the "$ENV{PATH}".
Workaround is to invoke perl as
perl ./filename

FindBin is supported as part of the core perl distribution. Please send
bug reports to <[EMAIL PROTECTED]> using the perlbug program included
with perl.
