8.115. FindBin

Finds the
full path to a script's bin
directory, letting you use relative paths to that directory without
needing to know the actual location:

use FindBin;
use lib "$FindBin::Bin/../lib";

or:

use FindBin qw($Bin);
use lib "$Bin/../lib";

FindBin exports the following variables:

$Bin
Path to bin directory from which script was
invoked

$Script
Basename of script from which Perl was invoked

$RealBin
$Bin with all links resolved

$RealScript
$Script with all links resolved

If you invoke Perl with the -e option or read
the Perl script from STDIN, then FindBin sets both
$Bin and $RealBin to the
current directory.
