Thanks for the response Mansur and Henrik - much appreciated. Mansur - Great, this looks much better!
Henrik - I have been looking ath the articles on ProDevTips and some of the libs on bitbucket - very helpful as well. What I'm really trying to do is have an easy way to invoke arbitrary shell commands that may be piped, process the result in pico and maybe use that as the input for another command. I haven't found a generic example yet that doesn't specify the command specifically that allows arbitrary piping and still gives you access to intermediary results. Feel free to point me to any additional examples that go beyond calling one hardcoded command. Thanks again and I'm sure I'll be back with more questions!
