Yet another example for you... (not that you need another, though)
I do the following for one of my mod_perl apps in which I use warn to output debugging & status information to Apaches error_log:
$SIG{__WARN__} = sub {
$msg = undef;
foreach (@_) {
$msg =~ s/ at.*$// unless $msg =~ /(uninit|deprec)/;
}
print STDERR 'MyApp...' . $msg;
}
Where I really only want to see the line number if it's an uninitialized or deprecated warning message. One could very easily add a timestamp to this, too.
