  • @Pratap just to again demonstrate my point that you need to tell us what kind of "pattern matching" you actually want to do, this is doing yet another type of "pattern matching" different from the 2 in my answer (this time it's partial-line regexp matching) which will once again produce the output you show from the input you show in your question. You really should come up with a better example that'll actually test your requirements. Commented Aug 6 at 12:43

    .... and if you add -F then it'll become a partial-record, partial-line string match solution, and if you also add -x it'll become a partial-record, full-line string match solution, etc. - all of which will produce the output in the question but would all behave differently given different input.

    right, I'm not saying there's any issue with your answer, just pointing out to the OP that their requirements aren't clear and their example needs to be updated to really test whatever their requirements are. Commented Aug 6 at 14:35
