Shouldn't following snippet throw error message when
it is called without any parameter?
Because this didn't have an error.
If you want it to quit, force it to quit.
die "No output specified" unless defined $output;
Oh, my understanding is that when I specify
"output=s"
its a mandatory parameter and if not specified on command line,
GetOptions should return error.
Am i missing something?
Yes. What the documentation means is that the ARGUMENT to the parameter
is mandatory, not the parameter itself.
myprog --output
will cause an error, but
myprog
and
myprog --output=file
will not.
