The following example shows how a complicated string, such as the date / time string from the unix "date" command, can be matched against a regular expression defined as a constant. The original regular expression is 5 lines long. use Regexp::Constant; my $date = "Mon Oct 25 11:59:13 EDT 2004"; print $1 if $date =~ /@{[REGEX_SHELL_DATE]}/; exit();
