I'm making assumptions but I guess you mean that errors and warnings generated by
warn or
die go to STDERR whereas normal messages generated by a plain
print without a filehandle go to STDOUT. On a *nix system you can run a script from the shell (Bourne, Korn, Bash) like this
script_name > output_file 2>&1
which directs STDOUT of the script into the "output_file" and also directs STDERR (file descriptor 2) into STDOUT (file descriptor 1). That way, you can get both STDOUT and STDERR into one file. I'm not sure what you would do in a MS Windows environment, perhaps other Monks can tell you (and me) what to do there.
I hope this is of use.
Cheers,
