Thanks for your solution IPC::Run is probably the best way to go. If you set $|++ in timestamp.pl we have it.
perl -MIPC::Run=run -e ' run( [ "perl", "timestamp.pl" ], "1>", sub { print "out " . time() . " " , @_ }, "2>", sub { print "err ". time() . " " , @_} ) ' out 1215247029 1215247029 info err 1215247029 1215247029 warn err 1215247029 1215247029 warn out 1215247029 1215247029 info err 1215247029 1215247029 warn err 1215247029 1215247029 warn out 1215247030 1215247030 info err 1215247030 1215247030 warn err 1215247030 1215247030 warn err 1215247030 1215247030 warn err 1215247030 1215247030 warn out 1215247030 1215247030 info err 1215247030 1215247030 warn out 1215247030 1215247030 info out 1215247030 1215247030 info out 1215247031 1215247030 info out 1215247031 1215247031 info err 1215247031 1215247031 warn err 1215247031 1215247031 warn out 1215247031 1215247031 info err 1215247031 1215247031 warn out 1215247031 1215247031 info out 1215247031 1215247031 info err 1215247031 1215247031 warn err 1215247031 1215247031 warn

    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
