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:
$BinPath to bin directory from which script was invoked
$ScriptBasename 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.
