Post #231,660 by admin 10/31/05 10:18:59 AM Reply	Re: Context Normally, I would just say "No." as I hate reading my own Perl, let alone someone else's. But had I looked at it (shudder) I might have commented that my $output_dir_exists = opendir( OUTPUT, "autocomm_out" );\nmkdir "autocomm_out" unless $output_dir_exists; might work just as well like: mkdir "autocomm_out" unless -d "autocomm_out"; Regards, -scott anderson "Welcome to Rivendell, Mr. Anderson..."

Post #231,668 by ben_tilly 10/31/05 11:30:32 AM Reply	And I would point out that... you really want to check whether mkdir succeeds. Perhaps you don't have permissions to the directory it is in? Perhaps there is a file there of that name? This is somewhat mitigated by the fact that he shortly afterwards tries to create a file in that directory and checks $! there. So he will notice the error. But good habits are good habits.

Post #231,711 by admin 10/31/05 2:21:34 PM Reply	How to do that... mkdir($foo) or die "Unable to make directory!" unless -d $foo; ? Does that need parentheses anywhere? Note that I was just demonstrating using -d, and not actually putting any thought into the answer whatsoever. ;-) Regards, -scott anderson "Welcome to Rivendell, Mr. Anderson..."
Post #231,719 by ben_tilly 10/31/05 3:07:35 PM Reply	That works but... There is a reason why Perl does not let you nest if's directly. It is confusing. Perl allows enough cryptic things, but even Larry drew the line at that one. Create a block for that. They're cheap. \nunless (-d $foo) {\n mkdir($foo) or die "Cannot mkdir '$foo': $!";\n}\n Cheers, Ben I have come to believe that idealism without discipline is a quick road to disaster, while discipline without idealism is pointless. -- Aaron Ward (my brother)
