in reply to Avoiding Hardcoded path of Perl.exe in coding

On Mac OS X v10.6 $^X does not give an absolute path, Instead I just get "perl". On linux I get "/usr/bin/perl" for $^X, on windows I get "C:\Perl\bin\perl.exe" for $^X.

If you happen to need the full path, and you want it to work cross platform, this should always give a full path, regardless of platform:

use Config; print $Config{perlpath}
