FindBin(3) Perl Programmers Reference Guide 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 AUTHORS FindBin is supported as part of the core perl distribu tion. Please send bug reports to <perlbug@perl.org> using the perlbug program included with perl.
