Hi All, I have a variable I'm reading off of the command line:
my $option = shift; That variable should hold a number between 1 and 31 (yes, a day of the month) I am checking to make sure that the number does indeed lie in that range. However, I need to pass that variable to another system command which expects any "day" value less than 10 to have a leading zero, so 7th day of the month should say '07'. How can I check for that leading zero? If it's missing, I know I could easily: $option = "0".$option; But I can't seem to figure out an easy, clean way to check for it. --Thanks, --Errin -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] <http://learn.perl.org/> <http://learn.perl.org/first-response>
