I really meant 'incorrect' in its usage, not the syntax -- he was using it
in a void context.

Yes, that is an incorrect way to use the ?: operator -- the operataor is
handed an expr

Be warned that readdir() returns NAMES, not PATHS.
opendir DIR, "/some/dir";
@files = readdir DIR;
closedir DIR;
@files will contain (".", ".."

Did you chdir to the directory? Otherwise your script might be checking the
wrong directory.
opendir(DIR,"/mydir");
@array = readdir(DIR);
chdir "/mydir";
foreach $dup (@array){
(-d $dup) ? print "yes: $dup \n": print "no: $dup \n";
}
