How do I direct the messages destined for STDERR and redirect them to
STDOUT?
I have a perl script A that calls another program B. If there is bad input,
Program B dumps out a lot of error messages through STDERR. I want to be
able to stop my perl script when it detects messages coming from program B.
What is the best way to do that? One way I thought of is by redirecting
error messages to STDOUT and capture it in my perl program and TERMINATE the
perl program if it detects anything. (when program B runs normally, there
is no output)
