karthikm897 you are correct that you don't need to tie the file handle with IO::Callback. The trick there is to use the select command. On the other hand for STDERR there is a fair amount going on in the background with perl so I would reccomend either looking at the perl documentation for sigtrap or working with the special %SIG variable to target specific error message types rather than redirecting STDERR wholesale.
