I have a list of log files that I create as part of a video encoding script that I wrote.

I would like to search all of them and print out certain statistics from the encode - how fast they were encoded, what settings were used, etc.

I can search for the average framerate in one file via this 1 liner:

cat ${filename} | grep average

which outputs:

 work: average encoding speed for job is 23.211176 fps

and search for the ratefactor:

cat ${filename} | grep RF

I would like to search all files in the directory and print off one, or prefereably both pieces of information along with the filename. Is there any way I can use find or grep to get this in a one-liner, or do I need to write a script?

I would like output like this:

/home/javanix/filename.log
    <RF line>
    <average line>

I would like this to either work using FreeBSD 9 or Ubuntu 12.04.
