I have a dir and sub-dirs underneath it.Inside subdirs, i have files with extension *.mat( and may be some other dirs).

I am performing a recursive fn.

sub readFiles {
    my $ipath = $_[0];
    my $afile;
    opendir(sDir, $ipath) || die "unable to open sDir: $!";
    my @files = grep { /\.mat$/ } readdir(sDir);

    foreach (@files){
        print FILE "$ipath\\$_"."\n";
    }
    closedir(sDir);
}

But I need to say, based on a dir (argument to readFiles), check if there is any other dir, if so readFiles again. My question is, what is the command in perl that "checks if there is a directory in a given path). Thanks.
