Jacob Tolar commented on OOZIE-2150:
------------------------------------
I agree that this would be a nice feature, but it won't work nicely all the
time - a shell action isn't necessarily running a script (you can ship and run
a binary, or use an interpreter in <exec> and a a script as an argument).
I imagine you could catch many/most cases if you use a library (e.g.
http://tika.apache.org/ ) to guess the type of file in <exec>, and print it if
it doesn't look like an executable.
if this approach makes sense, I could work on this.
