Hi, $1 is reset on each attempted match, so if a failed match occurs after your last match, $1 will be unset. 

perl -ne '$string=$_ if /Successfully sent/;  $match = $1 if $string =
+~ /^(.*) INFO.*$/; END{print $match}' $logfile

Hope this helps!


The way forward always starts with a minimal test.
