I know I've done this before, but I'm not sure what I'm doing
differently today. I'm trying to capture a simple command-line option
like so:
my $debug = 0;
if(grep(/--debug=(\d+)/, @ARGV)){
$debug = $1;
print "debug: $debug\n"; # Error here
}
But I keep getting "Use of uninitialized value in concatenation (.) or
string" when I try to do something with the debug variable. How can
$1 not be initialized? If it's matching, then it should have a value,
no?
TIA
Joel
