[ILUG] shell pipeline error

[ILUG] shell pipeline error

*bzzst*
Command 2 still run => command 3 still run.
The problem is I can't find a way to combine a pipe (|)
and logical and (&&). Alternatively is there a way
to get a pipeline to return the error code of the first
command and not the last. Even better would be for
a pipeline to return the error code if any command in
the pipeline returns "error".
