Re: Is readdir ever deterministic?

I'm not qualified to comment on the variations among systems or the lack of determinism, but as far as coding defensively, you could just put a filter on the files with grep :

foreach my $file ( grep { !/^\.{1,2}$/ } readdir DIR ) {
    munge($file);
}

perl -e 'print "How sweet does a rose smell? "; chomp ($n = <STDIN>); 
+$rose = "smells sweet to degree $n"; *other_name = *rose; print "$oth
+er_name\n"'

Well, being truly defensive, you should have written: `foreach my $file ( grep { !/\A\.{1,2}\z/ } readdir DIR ) { munge($file); }` [download] Or else the day someone creates a file named dot-newline or dotdot-newline, you'll be very angry. -- Randal L. Schwartz, Perl hacker	[reply] [d/l]
