Noob question here, trying to wean myself off of IDEs. In editors/ides such as eclipse and textmate, there are shortcuts to quickly find a particular file in a project directory.

I have a binary program* which takes the contents of a supplied file, processes it, and prints the result on the screen through stdout. For an automation script, I would like to use a named pipe to send data to this program and process the output myself.

But in modern scripting environments like Bash, I have always prefered the convention ...
