Hi, Excuse me for posting to this old threat, but I run in a similar situation where IPC::Run and Log::Log4perl were combined. I must remark that the title is actually misleading because no one has mentioned log4perl in his/her solution. Thus I will:

use IPC::Run qw(run new_chunker);
# snip-snap-snip
# ...

my @cmd = qw(find /usr/bin -type f);

run(\@cmd, "1>", new_chunker, \&logSdtout, "2>", new_chunker, \&logSdt
+err);

sub logSdtout
{
 $logger->info(@_);
}

sub logSdterr
{
  $logger->error(@_);
}

edit: you need to pass the filter "new_chunker" to IPC::Run to break the output from your external program into newlines. Otherwise you will run into strange exceptions (undefined values) causing IPC::Run to fail. Cheers, Daniel
