FindBin(3) FindBin(3)
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
