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
