I dont know much about bash. I want to do command line parsing. The following is for ex a ping result. I just want to parse some part from the statistcs. lets say just just rtt min. How to do that?
If some one can give me a link to some page how to understand this, that would be great too.. my google search have given me nothing. (Actually this topic is very new to me so most probably my keywords were not correct).

You can pipe answer to tail, set tail params to get last line, and then use sed to extract value you need
