OK thx guys!

mailog="/tmp/maillog"
last_record="Jul 15 22:09:10"
File.open(mailog, 'r+').each { |line|
     p line if line =~ /^#{last_record}/o
}

But now, what is the diff between

File.open( "maillog" ).each do |line|
and
File.open("mailog").each { |line|

one better, or more ruby standard?  I did not see a diff.
Personally I like "without the do" as there is less to type.
