Reads a file in reverse until the date is nolonger today. Useful for looking for errors in a log file that uses date stamps like Sun Aug 12 08:00:00 2001. I am using it for looking for oracle errors in my alert log.

my $file;
my @lines;

open FH, 'yourlogfile.log';

@lines = <FH>;
LINE: while ($file = pop @lines) {

    if ( $file =~ m/^ORA*/ ) { 
    print "$file\n";
    }
    last LINE if ($file !~ m/^$today*/ && 
$file =~ m/^(\S+\s+\S+\s+\d+)\s+\d+:\d+:\d+\s+(\d+)/x );
}
