how to redirect STDERR and STDOUT to a file when running as a windows service?

toadi has asked for the wisdom of the Perl Monks concerning the following question:

Hello,

I have a perl script as a service in windows:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\daemon\Parameter
+s]
"Application"="C:\\perl\\bin\\perl.exe"
"AppParameters"="c:\\server\\server.pl"
[download]

I installed it wit srvany.

Now I have a debug switch I can turn on and then all the print statements get printed. Also there are some issues throwing perl warnings. I tried to redirect with >> and 2>>, but this doesn't work while running as a service.

I tried to create a bat file, but then I can't stop the service anymore.

So I need some guidance how to redirect the STDERR AND STDOUT to a file when running as a windows service.

redirect your standard output and error by opening the log file , this way : `open ( STDOUT, ">>$logfilename" ) or die "aargh... $!"; open ( STDERR, ">>$errorfilename" ) or die "aargh... $!";` [download] In case you'd rather use only one file, you could do : `open ( STDERR , '>>$logfilename' ) or die "aaaagh... $!"; open ( STDOUT , ">&STDERR" ) or die "aaaagh... $!";` [download]	[reply] [d/l] [select]

I tried to redirect with >> and 2>> Instead of doing that, just pass a parameter to the script (eg: "-d") and then in the script, check the presence of that parameter (Getopt::Std, Getopt::Long) and open the necessary files. -- David Serrano	[reply]
