I stumbled over a domain name called "betterthangrep.com and thought "wow, bold statement". But i liked the testimonials as well as the featurelist so i played a round a bit and you really get the feeling ack is doing better then grep in the metter of "output what you search for".
I will go on with my investigation, lets see if i find something i can add to this entry.
Easy task, you want to listen to some files in your audio directory. You can list the files via ls and also grep them by piping the output of ls. But how do you get this result to the mplayer? By using xargs.
ls | grep '$mynameschema' | xargs mplayer
