Manpages FindBinSection: Perl Programmers Reference Guide (3perl)Updated: 2001-02-22 Index Return to Main Contents NAMEFindBin - Locate directory of original perl scriptSYNOPSISuse FindBin; use lib "$FindBin::Bin/../lib"; or use FindBin qw($Bin); use lib "$Bin/../lib"; DESCRIPTIONLocates 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 BUGSif perl is invoked as
perl filenameand 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 AUTHORSFindBin is supported as part of the core perl distribution.
