in reply to Re: Re: open failure code
in thread open failure code

Though this works, the ternary operator, like the grep and map operators, should not really be use in void context.
if (open(FH,"<".$log) { print "opened\n"; } else { print "unable to open $!\n"; }
is preferred.

    Of course the same could be done just with proper logical short circuit operators. Prefer the low-precedence ones for this sort of thing:

    open FH, "<", $log and print "Success\n" or print "Failure\n";

    That avoids trinaries and if/else's.
