I wrote a program in php which includes the function is_dir() which returns whether the specified path is a directory (1) or a file (0). I now need to translate it into perl, however I have been unable to find the comparable function for PERL. Does anyone know if one exists, and if so, what is it?

Well, in perl you can run it through an "if" statement:

sub is_dir() {
if ( -d $_[0] ) { return 1; } else { return 0; }
}

thank you very much for the reply.

If i read in a directory's contents (currently using perl on OS X) the only items that -d labels as a directory are "." and "..". None of the subfolders are returned as a directory.

If -d doesn't work theres most likely a bug in your script.
