What specifically did you try that failed? "does not work" can mean a lot of different things. See I know what I mean. Why don't you? and How do I post a question effectively?. If you post code showing us what didn't work, we can do a lot more in showing you what will. I am also unsure what you mean by "using anchor tag".

Assuming you have a variable $str that contains 03:20:21 - PID: 11500 - kernel bitness: 64, you can output the desired string with the line:

print $str =~ /kernel bitness:\s(\d*)/;

If this does not work for you, post code and sample input and output so we can refine the approach. See perlretut for more guidance in constructing regular expressions.
