I think this is where most are confused with your question.  What do
you mean to pipe the "actual return" to stdout?  A blank line is piped
to stdout (echo "line 1";pidof mysqld;echo "line 2"  will yield line
1, blank line, then line 2 which will really be line 3 of the output)
hence where the confusion lies as to what you mean by the "actual
return". Maybe if you described the bigger picture of what you are
trying to do (vs just that one single line) it would be easier for us
to determine what may help you accomplish that.
