Maybe, redirect output to a file first time then do wc -l <file>?
If awk is running twice -- the second time to get a occurence count from the first awk's output -- it doesn't seem like any parallelism is actually possible. And going to a disk file would actually slow things down a bit---stashing the results of the first awk into an environment variable and echoing that into the second awk would be faster. Plus... you eventually have to clean up those intermediate disk files.

@wikigeek: Deleting your questions and other relevant posts is not acceptable behavior at LQ.

Your questions and reply posts are all part of the public, growing knowledge base which makes the LQ forums useful to yourself and others.

When you post a question you are asking others to volunteer their own time to formulate a response, and to contribute their knowledge for your own benefit and that of future visitors.

Deleting your own questions and posts is disrespectful of the time others have generously given to help you, and removes the context of their replies rendering the thread useless to future visitors.

To help keep the quality of questions and resulting answers useful for everyone, please review the Site FAQ, and in particular the Welcome page and the links it provides when posting questions in future.

This thread is now closed, with thanks to all who contributed usefully.
