If you are just going to print the day number and you have other dates in a
similar format why not just use:
print +(split /\s+/, $date)[2];
Well, in this particular instance, I am. However, there have been at
least a few times in the past that I've wanted to achieve the same thing
and it always ends up looking like comic book curse words. Also, I
prefer to validate the input. This example would match even if the third
column weren't digits (more specifically, digits in the range of 1 to
31).
Thanks.
OK, how about this.
This however does not check whether the month can have 31 days.
#!/usr/bin/perl
use strict;
use warnings;
my @dates = (
"Wed Jun 7 14:27:38 2006",
"Wed Jun 47 14:27:38 2006",
);
foreach my $date ( @dates ) {
my $day_number = ( split /\s+/, $date )[2];
if ( $day_number =~ m/
^(?:
[12]?[1-9] | # 1-9, 11-19, 21-29 or
[1-3]0 | # 10, 20, 30 or
31 # 31
)$
/x ) {
print $day_number, "\n";
# Or whatever you want to do with the day number
}
}
